MULTIPLE BATTERY SYSTEM FOR A MOTOR VEHICLE

摘要

An electrical system for a motor vehicle includes first (54) and second (56) battery sets. The first battery set generally supplies power to vehicle electrical loads while the second battery set is used to energize the engine starter system (64, 66). The vehicle's engine driven alternator (28) is connected to recharge the first battery set. Recharging of the second battery set is provided by a charger (60) connected to draw power from the first set and to transfer the power to the second set.
