For vehicles with CO2 reduction technologies, hybrid vehicles and electric vehicles
GS YUASA offers Auxiliary and Back-up Automotive Batteries for modern vehicles with CO2 reduction technologies as well as hybrid vehicles and electric vehicles.
GS YUASA Auxiliary VRLA batteries vary in size and specification dependent on the demands placed on it by the vehicle electrical system. They can be used as a safety back-up to support the main battery when required or to provide voltage for specific vehicle systems all of the time. They are normally installed in the inside of the car such as a trunk room or under a back seat. Therefore, the structure which discharges harmful gasses of a battery into the outside of a car is required. GS YUASA Auxiliary VRLA battery series perfectly install it. The alloy of the Auxiliary VRLA battery can absorb oxigen gas. In case of overcharging, exhaust valves discharge gasses into the outside of the car. They also have a full sealed cover, vent and special separators for the alloys.
Application Areas of Auxiliary VRLA batteries
1. IC Dual Battery Systems: The dual battery system isolates all power supply sensitive electrical components which may be affected by low voltage from the primary battery during the engine starting phase. Two contact switches are used to change the power supply into two separate circuits when an engine start is required. Electrical power is then supplied to the sensitive electrical components from the secondary battery when an engine start is in progress. The primary battery supplies power to the starter motor and maintains essential power to the Engine Management System (EMS) which is essential for engine starting.
2. Hybrid Vehicle Auxiliary Battery: Most Hybrid vehicles feature a conventional 12 Volt auxiliary battery in addition to the high voltage hybrid system battery. The 12 Volt battery is not used for engine starting or to power the traction motors but is used to supply power to accessory systems, headlights, audio systems and computer controls.
3. Electric Vehicle Auxiliary Battery: Electric vehicles feature a conventional 12 Volt auxiliary battery in addition to the high voltage traction battery. The auxiliary battery is not used by the traction motor but is charged by the traction battery and is used to support all of the electrical systems on the vehicle with the exception of air conditioning and heating system.
