Batteries that every vehicle is keen on.
The essential role of the 12V lead-acid battery.
The job description of the 12V battery does not fit on a business card. It is responsible for so many things; nothing works without it. It provides the necessary energy to activate the safety relay and connect the high-voltage battery to the board net and electric engine.

Main electrical loads are on the 12V battery
  • Standby power for security systems (alarm system, sensors, cameras)
  • Standby power to several ECUs and memory
  • Door locking (+ possibly BT or WiFi for hands-free access via mobile, or remote access/ control via app etc.)

Main electrical loads are on the 12V battery
  • When the lead-acid battery is discharged, the car can’t start
  • Provide power to the relays/ safety contactors to activate the HV battery
Main electrical loads on the DC/DC converter, 12V battery as backup
  • Backup system capable of directly powering specific secondary loads
  • Stabilizes overall electrical system voltage
System failure
Main electrical loads are shifted from DC/DC to 12V battery
  • Power support to safety-critical loads such as power steering, ABS and brake boosting, door locks, emergency lights and e-call system (if installed) as the main power unit
  • Critical function in case of system failure
