![]() ![]() The 12 Volt battery is not used for engine starting or to power the traction motors but is used to supply power to:Įlectric vehicles such as the Mitsubishi i-miev feature a conventional 12 Volt auxiliary battery in addition to the high voltage traction battery. Since Ive installed this I havent had to jump start my truck. Most Hybrid vehicles such as the Toyota Prius feature a conventional 12 Volt auxiliary battery in addition to the high voltage hybrid system battery. Visit Schumacher Electric for portable jump starters, battery starters, EV chargers. Once the auxiliary battery is fully charged contact 2 will open to prevent damage to the axuiliary battery and reduce alternator and consequently engine loads to save fuel and reduce emissions. If the system detects a low auxiliary battery voltage contact 2 will remain closed once the engine is running to enable the auxiliary battery to be fully charged by the alternator. The primary battery is being charged by the alternator and the secondary battery is isolated from the circuit. The primary battey supplies the starter motor and the secondary battery supports power supply sensitive components System Conditions – Engine Running Alternatively, you can attach the battery tender/charger terminals to hook directly to the. IC Dual Battery System Operation System Conditions – Start Required The charger comes with the usual red and black clamps. IC Dual Battery System Components System components: Primary and secondary battery voltages are monitored to ensure sufficient voltage is available for the next start event and charge can be supplied to the secondary battery when required. 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. Two contact switches are used to change the power supply into two separate circuits when an engine start is required.Įlectrical power is then supplied to the sensitive electrical components from the secondary battery when an engine start is in progress. 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. ![]() The battery was a bit drained and the car had a hard time getting. Auxiliary batteries vary in size and specification dependent on the demands placed on it by the vehicle electrical system and 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. I bought this to keep a battery charged on a classic car with an Optima Redtop battery (gel). Maintains towed vehicle's battery charge while in tow. Universal and can be used with all braking systems. This dual rate battery charger handles all your 6V and 12V battery charging needs automotive, RV and other applications. Make sure this fits by entering your model number. ![]() Modern vehicles with CO2 reduction technologies, high levels of specification, and new electronic driver aids may feature an auxiliary battery alongside the main vehicle starter battery or high voltage system battery on Hybrid and electric vehicles. Available at a lower price from other sellers that may not offer free Prime shipping. ![]()
