EV Charging Infrastructure Security: 9 Best Practices for India

India’s EV charging ecosystem is expanding rapidly. According to the Ministry of Heavy Industries’ official public charging station data, India had 52,718 public charging stations as of 21 July 2026, including 16,561 public charging stations equipped with fast EV chargers for cars.

As charging networks become larger, they also become more digitally connected. Modern charging stations can communicate with vehicles, Charging Station Management Systems (CSMS), mobile applications, payment gateways, cloud services and remote-maintenance platforms. This means EV charging infrastructure security must be considered during charger procurement, network design, installation and long-term operations rather than being added after deployment.

The cyber risk is not hypothetical. In its official Safety of EV Charging Stations response, the Government of India stated that EV charging stations are susceptible to cyber-attacks and cybersecurity incidents. It also confirmed that CERT-In had received reports of vulnerabilities in products and applications related to EV charging stations and issued alerts and vulnerability notes recommending remedial measures.

For operators that need deeper background on threats, charger vulnerabilities and CSMS risks, SpeedCharge’s EV Charging Station Security: Cybersecurity Guide for India 2026 provides a detailed foundation before implementing the nine practices below.

Why EV Charging Cybersecurity Needs a Multi-Layered Approach

An EV charger should no longer be viewed as only an electrical appliance.

A connected charging ecosystem can include:

• EVSE hardware

• Embedded firmware

• Communication modem

• OCPP connection

• CSMS platform

• Administrator dashboard

• Mobile app

• Customer account

• APIs

• RFID or QR authentication

• Payment gateway

• Cloud database

• Remote-support tools

• Energy-management systems

A weakness in any of these layers can affect the wider charging service.

The Ministry of Power’s Guidelines for Installation and Operation of Electric Vehicle Charging Infrastructure-2024 apply across private, semi-restricted and public charging infrastructure and aim to support safe, reliable and accessible charging networks.

For CPOs, EV charging infrastructure security therefore needs a defence-in-depth strategy covering hardware, software, communications, identities, vendors and operational processes.

1. Maintain a Complete Inventory of Chargers and Digital Assets

The first security rule is simple: you cannot secure infrastructure you do not know exists.

A Charge Point Operator should maintain an accurate inventory of every deployed asset.

For each charger, record:

• Manufacturer

• Charger model

• Serial number

• Physical location

• AC/DC classification

• Power rating

• OCPP version

• Firmware version

• CSMS connection

• Communication method

• IP/network configuration where relevant

• Certificates

• Vendor-support status

• Last firmware update

• Remote-access configuration

The inventory should extend beyond physical chargers.

CPOs should also document:

• CSMS platforms

• Production servers

• APIs

• Customer applications

• Administrator accounts

• Payment integrations

• Cloud infrastructure

• Certificate-management systems

• Vendor accounts

• Support tools

Create a Risk Register

After building an inventory, classify assets according to their potential impact.

A high-power public DC hub managed through a central backend has a different risk profile from a private AC charger inside a controlled parking area.

Critical systems may include:

• CSMS administrator accounts

• Production databases

• Payment systems

• Fleet-wide remote commands

• Certificate-management services

• Firmware-management infrastructure

An updated asset register gives EV charging infrastructure security teams the visibility needed to identify vulnerable equipment, prioritise patches and respond quickly when a supplier reports a security issue.

Businesses still planning a deployment should also read SpeedCharge’s EV Charging Station Setup Guide before selecting chargers, electrical infrastructure and backend systems.

2. Secure the Physical EV Charger

Cybersecurity begins at the physical charging station.

Public chargers may be accessible 24×7, which means an attacker may have direct physical access to the equipment.

Operators should assess:

• Service-panel security

• Maintenance ports

• Communication modules

• Local administrator interfaces

• USB or diagnostic interfaces

• Network connections

• Charger enclosure

• Firmware-access mechanisms

Recommended measures include:

• Locking service compartments

• Restricting maintenance interfaces

• Removing unnecessary open ports

• Changing factory-default credentials

• Using tamper-resistant hardware where appropriate

• Restricting technician access

• Monitoring physical tampering where supported

• Protecting communication equipment

• Using verified firmware

Electrical Safety Still Matters

Cybersecurity does not replace electrical safety.

The Bureau of Indian Standards currently highlights IS 17017 (Part 23):2026 for DC Electric Vehicle Supply Equipment. The standard covers areas including EVSE functions, vehicle communication, electrical protection, cable requirements and emergency disconnection.

A professionally deployed charging station therefore needs both electrical protection and appropriate digital security controls.

3. Implement Strong Identity and Access Management

A secure charging network should never give every employee, technician or vendor unrestricted access to every system.

Permissions should match actual responsibilities.

A field technician may need to:

• Check charger status

• Review diagnostics

• Restart equipment

That technician does not necessarily need permission to:

• Export customer information

• Modify tariffs

• Add administrators

• Change payment settings

• Push fleet-wide firmware

• Access every charger in the network

Use:

• Unique employee accounts

• Role-based access control

• Least privilege

• Multi-factor authentication for sensitive accounts

• Strong credential policies

• Regular access reviews

• Immediate revocation when an employee leaves

• Controlled vendor accounts

• Logged administrator actions

Shared administrator usernames should be avoided wherever possible.

Control Third-Party Access

Charging networks often depend on:

• Charger manufacturers

• CSMS vendors

• Maintenance contractors

• Payment providers

• Connectivity vendors

• Software developers

Any permanent remote-access route can become a potential security exposure.

Vendor access should ideally be:

• Authorised

• Limited

• Logged

• Time-bound where practical

• Revocable

Strong access control is one of the most important foundations of EV charging infrastructure security, particularly because one privileged backend account may control many chargers simultaneously.

4. Secure OCPP Communication Between Chargers and the CSMS

Open Charge Point Protocol is widely used for communication between charging stations and backend platforms.

OCPP can support functions including:

• Charger status

• Authentication

• Transactions

• Meter values

• Configuration

• Diagnostics

• Remote start

• Remote stop

• Firmware management

However, “OCPP compatible” does not automatically mean “secure.”

Operators should verify:

• Which OCPP version is supported

• Which security profile is implemented

• Whether TLS is correctly configured

• How chargers authenticate

• How certificates are created

• How certificates are renewed

• What happens when certificates expire

• How remote commands are authorised

• Whether security events are logged

• How firmware updates are validated

The Open Charge Alliance’s Security Operations Guide provides practical guidance for secure implementation and operation of OCPP charging stations and CSMS platforms.

The Open Charge Alliance also explains that OCPP 2.x contains security functionality and that additional security enhancements can be applied to OCPP 1.6-J deployments.

For SpeedCharge readers evaluating protocol choices, internally link the OCPP vs OCPI guide here.

CPOs planning newer deployments should also review OCPP 2.0.1 for Indian CPOs, which covers device management, TLS, certificates, firmware, security logs and backend interoperability.

5. Segment EV Chargers From Other Business Networks

One compromised charging station should not automatically provide access to unrelated corporate systems.

Charging infrastructure should be appropriately separated from:

• Employee laptops

• Finance systems

• HR applications

• Internal databases

• Development environments

• Guest Wi-Fi

• Building-management systems where unnecessary

Depending on the architecture, organisations may use:

• Separate VLANs

• Firewalls

• Network access-control rules

• Restricted inbound connectivity

• Approved outbound destinations

• VPN-based administrative access

• DNS monitoring

• Traffic monitoring

Apply Zero-Trust Principles Where Practical

A device should not be trusted merely because it is connected to the company network.

Every critical connection should be evaluated according to:

• Identity

• Authentication

• Authorisation

• Device status

• Required access

This approach reduces lateral movement after a compromise.

For mixed charger fleets, segmentation becomes even more important because different manufacturers can use different firmware, communication modules and security-update processes.

6. Create a Formal Firmware, Patch and Supply-Chain Security Process

EV charging hardware can remain deployed for many years.

Its software cannot safely remain unchanged for the same period.

Before purchasing equipment, ask the charger manufacturer:

• How are vulnerabilities disclosed?

• How are operators notified?

• Are firmware packages signed?

• How is update authenticity verified?

• How quickly are critical vulnerabilities patched?

• How long will security updates be supplied?

• Can operators schedule deployments?

• Is rollback supported?

• How is end-of-support handled?

A recommended patch process is:

1. Identify the vulnerability.

2. Identify affected assets.

3. Assess severity.

4. Check actual exposure.

5. Obtain a trusted update.

6. Test it.

7. Deploy gradually.

8. Verify installation.

9. Monitor performance.

10. Update the asset register.

Evaluate Supply-Chain Risk

A charging system may depend on multiple external components:

• Operating systems

• Embedded libraries

• Modems

• Payment services

• Cloud providers

• API providers

• Firmware components

• Third-party applications

Cybersecurity clauses should therefore be included in vendor evaluation and commercial agreements where appropriate.

A charger with good electrical specifications but weak long-term security support may become difficult to operate safely before the hardware reaches the end of its useful life.

7. Protect APIs, Payments and Personal Data

Charging networks increasingly depend on APIs.

APIs may connect:

• Mobile apps

• Chargers

• CSMS platforms

• Payment systems

• Fleet applications

• Roaming partners

• Analytics systems

• Customer-support tools

Important API protections include:

• Strong authentication

• Object-level authorisation

• Rate limiting

• Secure token management

• Input validation

• API-key protection

• Logging

• Secret rotation

For example, logging into an application should not automatically allow a user to retrieve another customer’s transaction simply by modifying an ID in an API request.

Protect Payment Workflows

Charging transactions combine:

User Identity + Energy Consumption + Charging Session + Billing + Payment

This makes transaction integrity critical.

Payment systems should be appropriately isolated, and sensitive credentials or payment information should not be unnecessarily stored on charging hardware.

Protect Personal Data

The Ministry of Electronics and Information Technology published the Digital Personal Data Protection Rules 2025 on 14 November 2025 together with the enforcement timeline for the DPDP framework.

Charging businesses should understand:

• What customer information they collect

• Why they collect it

• Where it is stored

• Who can access it

• Which vendors process it

• How long it is retained

• How security incidents are handled

Privacy controls are part of EV charging infrastructure security because even a physically secure charger can be part of a wider data breach if a vulnerable app, API or cloud database exposes customer information.

8. Monitor the Network and Prepare an Incident-Response Plan

Security controls are much less useful if operators cannot detect suspicious activity.

CPOs should monitor events such as:

• Repeated failed administrator logins

• Unexpected remote start commands

• Unexpected remote stop commands

• Configuration changes

• Certificate errors

• New administrator accounts

• Abnormal API requests

• Firmware changes

• Suspicious communication destinations

• Repeated payment anomalies

• Large groups of chargers going offline unexpectedly

Logs from critical systems should be centralised where appropriate and protected from unauthorised alteration.

Follow CERT-In Requirements

CERT-In maintains the CERT-In Cyber Security Directions under Section 70B of the Information Technology Act concerning information-security practices and cyber-incident prevention, response and reporting.

Charging businesses should establish a process to determine:

• What happened

• Which systems were affected

• Whether customer data was involved

• Whether charging operations were disrupted

• How to contain the incident

• How evidence will be preserved

• Whether regulatory reporting applies

• How systems will be restored

A documented incident-response plan should identify who can:

• Disable accounts

• Isolate chargers

• Contact vendors

• Preserve logs

• Communicate with customers

• Approve recovery

• Assess reporting obligations

Incident readiness is a critical component of EV charging infrastructure security because decisions made during the first hours of a breach can determine whether the problem remains contained or spreads across the network.

Consider the Power-Sector Cybersecurity Context

The Central Electricity Authority publishes the CEA Cyber Security in Power Sector Guidelines, 2021 as part of India’s wider power-sector cybersecurity framework.

The precise applicability of particular obligations depends on the entity and infrastructure involved, but principles around access management, cyber hygiene and incident preparedness are increasingly relevant as charging infrastructure integrates more closely with electricity systems.

9. Test Security Regularly and Train Employees

Security should be continuously validated.

Useful activities can include:

• Vulnerability assessments

• Penetration testing

• API security testing

• Administrator-access reviews

• Firewall-rule reviews

• Firmware audits

• Backup restoration tests

• Vendor-access reviews

• Incident-response exercises

Test Recovery, Not Just Prevention

Operators should ask:

• What happens if the CSMS becomes unavailable?

• Can affected chargers be isolated?

• Are configuration backups available?

• Are customer-facing services recoverable?

• Can operations continue safely during limited connectivity?

• Is a clean recovery environment available?

High-utilisation locations should also consider redundancy.

If one compromised component can make an entire charging hub unavailable, the architecture may need stronger resilience.

Train People According to Their Roles

Cybersecurity training should differ by responsibility.

Technicians should understand:

• Secure maintenance access

• Credential handling

• Approved firmware

• Suspicious hardware modifications

Customer-support teams should understand:

• Account-verification procedures

• Social-engineering attacks

• Escalation procedures

Administrators should understand:

• Privileged-access risks

• MFA

• Security monitoring

• Incident escalation

Developers should understand:

• Secure APIs

• Secret management

• Authentication

• Dependency security

• Secure coding

People, technology and processes have to work together.

Common EV Charging Cybersecurity Mistakes

CPOs should avoid several common mistakes.

Assuming OCPP Compatibility Means Security

Compatibility only confirms protocol support. Security depends on implementation, configuration and operational practices.

Leaving Factory Credentials Active

Default credentials make infrastructure unnecessarily vulnerable.

Sharing Administrator Accounts

Shared accounts reduce accountability and make access revocation difficult.

Ignoring Firmware Support

A charger without security-update support can become a long-term operational liability.

Giving Vendors Unlimited Access

Third-party access should be restricted according to business need.

Treating Cybersecurity as an Annual Audit

Security needs continuous monitoring and maintenance.

Keeping Chargers on Flat Networks

Segmentation limits how far an attacker can move if a device is compromised.

Collecting More Customer Data Than Required

Unnecessary data increases breach impact and compliance burden.

How SpeedCharge Approaches Connected Charging Infrastructure

Reliable public charging requires more than installing EVSE hardware.

Charging hardware must work together with:

• Electrical infrastructure

• Network connectivity

• Charger-management software

• Remote monitoring

• Payment systems

• Maintenance

• Customer support

SpeedCharge provides commercial EV charging solutions for businesses and properties covering offices, hotels, malls, commercial properties, parking facilities and fleet applications.

For entrepreneurs planning a managed public charging business, SpeedCharge’s EV charging station franchise in India explains its charging-station partnership and franchise structure.

For broader company and network information, readers can also explore SpeedCharge’s connected EV charging infrastructure.

The key principle is that cybersecurity should be considered across the complete charging lifecycle:

Planning → Procurement → Installation → Commissioning → Operations → Updates → Decommissioning

Conclusion

India’s public charging network is expanding quickly, but every connected charger adds another digital asset that must be managed and protected.

Strong EV charging infrastructure security does not depend on one firewall, one antivirus product or one communication protocol. It requires multiple layers working together:

• Accurate asset inventories

• Secure charger hardware

• Strong authentication

• Controlled privileges

• Secure OCPP communication

• Network segmentation

• Firmware management

• API security

• Data protection

• Continuous monitoring

• Incident response

• Regular testing

• Employee training

The Government has already recognised cybersecurity risks affecting EV charging products and applications. As charging networks scale and become more integrated with apps, cloud platforms, fleets and electricity systems, security needs to be built into infrastructure from the beginning.

For Indian CPOs, manufacturers and infrastructure operators, the safest approach is to make cybersecurity a continuous operational discipline rather than a one-time compliance exercise.
