Abstract
An electrical system for a motor vehicle includes first and second 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. The vehicle's engine driven alternator is connected to recharge the first battery set. Recharging of the second battery set is provided by a charger connected to draw power from the first set and to transfer the power to the second set.
Claims13
An electrical system for a motor vehicle comprising:
- a first electrical power storage sub-system;
- a second electrical power storage sub-system;
- electrical power generation means for charging the first electrical power storage sub-system;
- means responsive to a state of charge for the second electrical power storage sub-system for transferring charge from the first electrical power storage sub-system to the second electrical power storage sub-system;
- and
- an internal combustion engine starter system connected to the second electrical power storage sub-system for energization of the internal combustion engine starter system.
A motor vehicle comprising:
- an internal combustion engine;
- an electrical starter system for the internal combustion engine;
- a starter battery system connected to supply power on demand to the electrical starter system;
- an electrical generator driven by the internal combustion engine;
- an electrical systems battery system connected to be charged from the electrical generator;
- electrical consumers connected to draw power from the electrical systems battery system and the electrical generator;
- and
- means responsive to a state of charge of the starter battery system for transferring charge from the electrical systems battery system to the starter battery system.
A multiple battery system comprising:
- a high cycle battery set having a nominal output voltage;
- means for charging the high cycle battery set;
- a power outlet for connection to electrical consumers from the high cycle battery set and the means for charging;
- an isolated battery set having a nominal output voltage;
- and
- means responsive to deviation from the nominal output voltage of the isolated battery set for transferring charge from the high cycle battery set to the isolated battery set and controlling rate of transfer.
