Battery temperature detecting device for a charger
First Claim
Patent Images
1. A battery temperature detecting device for use on a charger, comprising:
- a case having an upper shell and a bottom lid;
said bottom lid in abutment against said battery being made of material having good thermal conductivity;
said upper shell being made of material having low thermal conductivity;
a heat sensitive sensor disposed in said case being connected by wire to an inner circuit of said charger so as to transmit detected temperature to said inner circuit of said charger;
a fixing means being associated with said case or fixed to said charger for securing said case to said battery with said bottom lid having good thermal conductivity in abutment against the surface of said battery whereby said heat sensitive sensor can detect the temperature of said battery which is then transmitted to said inner circuit of said charger so as to cause said charger to continue or stop the charge operation according to the charging state detected by the temperature of said battery.

Abstract
A battery temperature detecting device adapted particularly for a charger can monitor the variation of temperature of a charged battery and the detected is transmitted immediatedly to an internal circuit of the charger. The present detecting device is equipped with a shell, a heat sensitive sensor disposed is the shell and coupled to the internal circuit of the charger, and a fixing member which can firmly attach the detecting device to the surface of a charged battery whereby the heat sensitive sensor can pick up the variation of temperature of the battery and the same is delivered by wire to the internal circuit of the charger.
