Cyber security warning for EV chargers

Experts say the EV network is vulnerable and, as it grows, will become a tempting target for cyber criminals. 

 

The main risk is from unauthorised access through unprotected devices connected to the EV charger network. For example, attacks could change voltage settings, potentially causing major damage. 

 

The UK Electric Vehicles (Smart Charge Points) Regulations say the design, manufacture and set up of charge points should provide protection. This includes risks to the electricity system, charge points and personal data of vehicle owners and users. This applies both before chargers are installed and for their lifetime. 

 

Proposals include thorough pre-installation inspections for allowed passwords, software updates, communication, data security and use. Once installed, secure updates for the chargers should protect against cyber-attacks. Sensitive information including login details shouldn’t be recorded in the system but stored securely. To prevent potential security vulnerabilities data that can’t be verified shouldn’t be kept. 

 

However, responsibility for regular security checks during setup and updates will still fall to charger owners. 

 

Despite these concerns, government grants are still available to encourage home owners, businesses and others to install EV chargers. Many of these schemes involve the installer applying for the grants. 

 

Most schemes come from the Office for Zero Emission Vehicles (OZEV) but will close on 31 March 2025. They include: 

 

The Workplace Charging Scheme. Businesses, charities and public sector employers can claim up to £350 per charging socket for up to 40 sockets across all their sites. 

 

Infrastructure grant for staff and fleets. Up to £350 per charge point socket installed and up to £500 per parking space enabled to a maximum of £15,000. 

 

Grants for landlords. Up to £350 per socket for up to 200 each year for residential properties and 100 commercial properties and for wider work. 

 

For renters or flat owners. Up to £350 to install a charge point at a dedicated off-street parking space. 

 

Households with On-Street Parking. Up to £350 to install EV charge points at residential properties with cross-pavement charging.
