Abstract
A lithium battery pack is described. The lithium battery pack includes a lithium battery having a plurality of battery units connected together in a series configuration, and an environmental management circuit in parallel with the plurality of battery units of the lithium battery. The environmental management circuit has a load distributed through the lithium battery, and circuitry operable to block energy directed to the lithium battery when a temperature of the lithium battery is below a predetermined threshold; and direct the energy to the load distributed through the lithium battery to warm the lithium battery.
