Protection circuit of high -temperature battery group

The utility model provides a protection circuit of high -temperature battery group, include: a plurality of battery cell to and electricity insurance and the line switching the same with battery cell quantity, battery cell is high -temperature battery, be connected with the consumer after a plurality of battery cell establish ties and be used for supplying power for the consumer, every battery cell and an electricity insurance are established ties to at battery cell and the parallelly connected line switching in the both ends of electricity insurance, the electricity insurance fuses when the battery cell of series connection with it trouble, and the circuit switch switches on when fusing in the electricity insurance rather than parallelly connected simultaneously. Because battery cell short circuit or when taking place other abnormal conditions, the electricity insurance fusing of series connection with it stops the current output of battery, can prevent the emergence of the dangerous accident of battery, and
