Title: Apparatus for determining battery pack temperature and identity
Inventor: BROTTO DANIELE C
IPC: H01M10/42
Filed: 1999-07-07
Granted: 2001-04-01
Abstract: A battery monitor system that determines battery pack temperature and battery pack identification. The battery pack includes a battery pack circuit having a thermistor and an AC circuit component. The battery monitoring system determines the battery pack temperature by measuring the resistance of the thermistor when the battery pack circuit is in a steady-state condition, and determines the value of the AC component based on a changing or dynamic electrical condition of the battery pack circuit. In one embodiment, to determine battery pack identification, an identification capacitor is connected in circuit with the thermistor. One terminal of a comparator is switched to a low reference voltage potential once the identification capacitor has been charged, and the output of the comparator gives an indication of the discharge rate of the capacitor, and thus its identification. In an alternate embodiment, the battery monitor circuit determines the identity of the battery pack by determining whether a thermistor does or doesn't exist, and if so, whether an identification capacitor does or doesn't exist.
