As with gasoline vehicles, electric vehicles require an accessory 12v battery. Mainly, it is used to power all the accessories such as door locks, radio, windshield wiper. It is also used to turn on the system needed to start the car. The high voltage battery is switched off when the car is switched off. It is therefore essential that the 12V battery is in good condition or you may need a battery replacement.
A car battery has an average life of about 5 years, however, a battery that is discharged too deeply or discharged too often will have a shorter life.
