Abstract
A rechargeable battery, module or a pack, having different levels of internal resistance that operate at different temperatures are disclosed. In a subfreezing environment, the battery can exhibit high resistance which once operated or activated, generates heat internally to warm up the battery quickly. Once the batter reaches normal operating temperatures, the battery can switch to a low resistance operating mode, thereby delivering superior power and energy despite operating in a very low ambient temperature.
