Charging ahead with GS Start/Stop & Hybrid Batteries

GS batteries offer a market overview of the latest technology of Start/Stop and Hybrid batteries charging modern vehicles.

Whilst vehicle battery sales typically thrive during winter, modern vehicle batteries require a little more attention. It is important to ensure that only a product with the correct specification, suitability and quality is being used. The replacement is not a straightforward fit-and-forget task for modern vehicles with latest the technologies.

Suiting Start/Stop Technology

Vehicles equipped with Start/Stop technology are becoming increasingly common. It is, therefore, important for technicians and factors to be well informed on the complexities and time required for the battery replacements.

A standard ignition vehicle will typically be started two or three times a day. However, with Start/Stop vehicles this can rise to over 50 times.

Two New Types of Batteries

To cope with the higher demand placed on the battery, GS introduced two new types. Firstly the absorbed glass mat (AGM) which is suitable for high specification vehicles and secondly the enhanced flooded batteries (EFB) suitable for lower specification vehicles. The technology used in these batteries offers much higher cyclic capability and durability to cope with the demands of repeated cranking cycles.

Like-for-Like 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. The GS AGM range includes 6 references while the EFB range has 13. These are fully maintenance free, built to OE standards and include advanced safety features.

Battery Configuration

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. This can be done quickly using the GS Yu-Fit configuration tool (pictured to the right). 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

Modern vehicles with CO2 reduction technologies, higher specifications and new electronic driver aids may feature an auxiliary battery alongside the main vehicle starter battery. Alternatively hybrid and electric vehicles feature a high-voltage system battery. Auxiliary batteries vary in size and specification and can be used as a safety back-up to the main battery. They can also be used 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). This 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. This 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. This 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.
