Battery power system for a vehicle
First Claim
1. A battery power system for a vehicle having an internal combustion engine with an alternator, an engine starting system, and electrical devices which are operable when the engine is off, the battery power system comprising:
- a battery pack having at least one high cold-cranking-ampere (CCA) battery having a first voltage coupled to the engine starting system and at least two deep-cycle batteries each having a second voltage different from the first voltage and connected in series to provide an output at the first voltage for powering the electrical devices when the internal combustion engine is off, said at least one high-CCA battery having a first voltage and providing sufficient cold cranking current for starting the internal combustion engine of the vehicle; and
a switch coupled to said serially connected deep-cycle batteries and said at least one high-CCA battery, said switch being operable to connect said deep-cycle batteries and said at least one high-CCA battery in parallel for charging by the alternator when the internal combustion engine is operating and to isolate said deep-cycle batteries from said at least one high-CCA battery when the internal combustion engine is not operating.

Abstract
A battery pack for providing electrical power to a commercial tractor/trailer vehicle has two 12-volt high-CCA batteries connected in parallel and two 6-volt deep-cycle batteries connected in series to power 12-volt electrical accessories such as devices for creature comforts. The two 12-volt high-CCA batteries provide sufficient cold cranking current for starting the engine of the vehicle. The two 6-volt deep-cycle batteries connected in series are used to power electrical accessories such as devices for creature comforts when the engine is not operating. A switch connects the serially connected 6-volt deep-cycle batteries in parallel with the 12-volt batteries for charging when the engine is running and isolates the 6-volt deep-cycle batteries from the 12-volt high-CCA batteries when the engine is off.
