Charging Modern VehiclesFitting Start/Stop and Hybrid batteries. With modern vehicles it is important to ensure that only a battery with the correct specification is being used.
SUITING START/STOP TECHNOLOGY Vehicles equipped with Start/Stop technology are becoming increasingly common, making it important for technicians and factors to be well informed on the complexities and time required for their replacement.
On vehicles with advanced technology, it is essential that the battery is replaced with one of the correct specification. If a vehicle is fitted with an AGM Start/Stop battery then the replacement must also be AGM Start/Stop. The same applies to EFB products.
On vehicles fitted with Battery Management Systems (BMS), it is essential to reprogram the unit via the on-board diagnostics (OBD) port to validate the newly fitted battery. Failure to do so can cause battery failure, system faults and in-car error messages or even a complete loss of Start/Stop functionality.
AUXILIARY/BACK-UP BATTERIES - AIDING ADVANCED SYSTEMS Modern vehicles with CO2 reduction technologies, higher specifications and new electronic driver aids may feature an auxiliary battery alongside the main vehicle starter battery or the high voltage system battery on hybrid and electric vehicles.
Auxiliary batteries vary in size and specification and can be used either as a safety back-up to the main battery, or to provide voltage for specific vehicle systems all of the time.
Case Studies Mercedes E and S Class vehicles feature an advanced brake by wire system: Sensotronic Brake Control (SBC), that relies on electrical power and a minimum system voltage; in the event of the main starter battery becoming too low or a charging system failure, the vehicles are equipped with an auxiliary battery as a safety back-up
Hybrid vehicles like Toyota Prius feature an additional, conventional 12 Volt auxiliary battery, which is not used for engine starting or to power the traction motors but to supply power to accessory systems, headlights, entertainment systems and computer controls
Electric vehicles like Mitsubishi i-miev feature an additional, conventional 12 Volt auxiliary battery that is not used by the traction motor but is charged by the traction battery and used to support all the electrical systems on the vehicle, except the air conditioning and heating systems |
