More sluggish function.Equally, temperature of the temperature sensor RT1 in Fig. 4 close to battery, in real time detection battery.Temperature sensor
RT1 characteristic is, when temperature rises, temperature sensor RT1 resistance reduces.
The operation principle of Fig. 4 circuits is：When temperature than it is relatively low when, temperature sensor RT1 detects temperature than relatively low,
Its resistance is bigger, causes operational amplifier chip U1 in-phase end higher than the voltage of end of oppisite phase, and the 1 of operational amplifier chip U1
Pin exports high level, enters logical AND gate U2A 1 input.Control module 20 detects low temperature simultaneously, sends open signal
Into logical AND gate U2A 2 input pins, from logical AND gate U2A phase and characteristic, logical AND gate U2A output and open
Open that signal is identical, the open signal driving switch module Q1 of logical AND gate U2A outputs makes heating module 40 generate heat, and heats battery.
Control module 20 constantly detects battery temperature by temperature sensor RT1 simultaneously, to adjust the pulsewidth of open signal, finally adds

Disturb, or control module 20 detects that temperature has exception error, the pin for causing to export open signal is high level always, logic
Two inputs with door U2A are all high level, and logical AND gate U2A exports high level, driving switch module Q1 conductings, heated mould
Block 40 heats, and causes the rise of battery core temperature to be even more than the temperature of its normal use.Now protection circuit works, and closes circuit
And stop heating.It is implemented as, when battery core temperature is too high, temperature sensor RT1 detects that temperature is too high, and its resistance subtracts
It is small to arrive smaller value, cause operational amplifier chip U1 in-phase ends voltage to be less than end of oppisite phase, operational amplifier chip U1 1 pin
Export low level and give logical AND gate U2A, now no matter logical AND gate U2A open signal input pin input is any level,
Logical AND gate U2A exports low level, turns off switch module Q1, stops heating.Control module 20 can be so effectively prevent to go out
