Title: Protection systems for rechargeable elements
Inventor: GOZLAN GILLES
IPC: H02J7/00
Filed: 1999-04-15
Granted: 2003-01-01
Abstract: The present invention provides a protection system that prevents a rechargeable battery from being overcharged into a dangerous operating mode. The protection system may generally be used as a backup system in conjunction with a smart electronic circuit which, when functioning in its normal mode, protects the battery cells against being overcharged. Typically, this protection system should preferably integrated into the battery cells. It could also be used as part of the battery pack electronics or part of the charger. The protection system will be activated before the battery voltage reaches a dangerous threshold value. According to one embodiment of the present invention, a rechargeable battery is coupled, in parallel, to a voltage dependent resistive element, such as a zener diode or a diac, having a threshold voltage just below the threshold operating voltage of the battery. A protection element, such as a positive temperature coefficient (PTC) device, a thermal fuse, or a bimetallic breaker, etc., is coupled, in series, to the battery or to the parallel circuit of the battery and the voltage dependent resistive element. When overcharging starts to occur and the smart circuit fails to function, the current flowing in the voltage dependent resistive element will activate the protection element to thereby halt the charging operation. According to another embodiment of the invention, a rechargeable battery is coupled in series with a fuse and in parallel with a power MOSFET transistor which is preferably thermally coupled to an overcharge detection device. The overcharge detection device will drive the power MOSFET. As soon as the battery voltage exceeds a predetermined level, the power MOSFET will be activated to short the battery cells, causing the fuse to blow up, thus isolating the battery. Either a thermal fuse or a regular fuse may be used in this embodiment. If a PTC device is used instead of a fuse, it will trip and limit the fault current to a low leakage current. By connecting a protection element in series with the battery, the battery is also protected from external shorting during transportation, for example. A protection method of the present invention is also disclosed.
