Abstract
A system and method to disconnect a battery from a load circuit when the battery temperature is outside a selected high threshold or a low threshold. A plurality of temperature sensors are provided for sensing a high battery temperature and a low battery temperature. If the either the high temperature sensor or the low temperature sensor outputs an error signal, the battery is disconnected from the load circuits. The disconnection from the load circuits is carried out by disabling at least four different circuits, any one of which alone will disconnect the battery from the load circuits. These four circuits include a battery switch circuit, a power control circuit, a charge control logic circuit and a voltage regulator circuit. The plurality of temperature sensors provides a backup system in the event any one of the temperature sensors is defective.
