Best dash cam for electric vehicles UK 2025, EV-specific considerations explained
Installing a dashcam in an electric vehicle requires awareness of the EV’s specific electrical architecture. The 12V auxiliary battery, high-voltage safety systems, and regenerative braking circuits all affect installation approach. LockCar manufactures dashcam and immobiliser systems fully compatible with all major EV platforms and installed by engineers trained in EV-specific procedures.
Installing a dashcam in an electric vehicle requires awareness of the EV’s specific electrical architecture. The 12V auxiliary battery, high-voltage safety systems, and regenerative braking circuits all affect installation approach. LockCar manufactures dashcam and immobiliser systems fully compatible with all major EV platforms and installed by engineers trained in EV-specific procedures.
EV electrical architecture and dashcam installation
Electric vehicles use a 12V auxiliary battery for low-voltage systems including infotainment, lighting, and the dashcam circuit, alongside the high-voltage traction battery for the drive motor. The 12V auxiliary battery is the correct power source for dashcam installation in most EVs, providing the continuous live circuit needed for always-on parking mode without drawing from the traction battery.
Tesla Model 3 and Model Y, BMW i4 and iX, Kia EV6, Hyundai Ioniq 5, and VW ID.4 all use 12V auxiliary batteries that support standard dashcam installation procedures. LockCar engineers follow EV-specific wiring procedures for each platform to avoid any interaction with BMS, OBC, or high-voltage safety circuits.
Parking mode considerations for EVs
EV parking mode has specific considerations. Many EVs enter a low-power standby state when the 12V auxiliary battery charge drops below a threshold, which can cause a dashcam in parking mode to drain the auxiliary battery if left for extended periods. LockCar dashcam systems include power management that limits parking mode current draw to avoid auxiliary battery drain issues on EV platforms.
For Tesla owners, the built-in TeslaCam USB dashcam function records to a USB drive using the vehicle’s traction battery. LockCar provides an additional forward-facing professional dashcam channel alongside the TeslaCam system, with the added benefit of a hardwired relay immobiliser that TeslaCam does not include.
LockCar relay immobiliser for EVs
LockCar’s EV-adapted immobiliser installation integrates with the drive circuit rather than a conventional fuel pump or ignition circuit. The relay break prevents the drive motor from engaging regardless of whether the keyless entry authentication has been completed by relay attack or BLE relay. The installation does not affect charging capability, regenerative braking, or any driver assistance feature on any supported EV platform.
