Abstract
A battery such as, but not limited to, electric vehicle battery packs and cells, lithium iron phosphate batteries, lead acid batteries, gel batteries, and absorbed gel mat batteries, may include a battery management system for engine start applications. The battery may include a first power port configured to receive power from a first power source and a second power port configured to received power from a second power source, whereby the first and second power sources are different.
Claims29
A battery, comprising:
- at least one battery housing;
- at least one battery cell positioned in the at least one battery housing;
- at least one battery management system configured to control aspects of use of the battery;
- at least one set of external electrical terminals configured to output electrical energy from the at least one battery cell to an external load;
- an input interface configured to receive electrical energy from an external energy source;
- and
- a conversion circuit positioned within the at least one battery housing and coupled to the input interface and the at least one battery cell, wherein the conversion circuit is configured to convert electrical energy received from an external power source, via the input interface, into charging energy suitable for the at least one battery cell.
4 more elements
A battery, comprising:
- at least one battery housing;
- at least one battery cell positioned in the at least one battery housing;
- at least one battery management system configured to control aspects of use of the battery;
- at least one set of externally accessible electrical terminals configured as bi-directional terminals configured to be coupled to a nominal 12-volt electrical system for both delivering and receiving electrical energy;
- at least one set of output-only terminals configured to deliver power for powering auxiliary loads distinct from the nominal 12-volt electrical system, wherein the power is delivered through the at least one set of output-only terminals at a second voltage that differs from the nominal 12-volt electrical system;
- a conversion circuit positioned within the at least one battery housing and coupled to the at least one battery cell;
- wherein the conversion circuit is configured to maintain simultaneous availability of nominal 12-volt electrical energy in the at the at least one set of externally accessible electrical terminals of the nominal 12-volt electrical system and availability of the power at the second voltage at the at least one set of output-only terminals;
- and
- wherein the power at the second voltage is electrically isolated from the nominal 12-volt electrical system.
