Circuit Description
Current detectION Circuit : R14, R15, R16,
U4
Battery charging current is changed voltage
through R14, R15, R16. This voltage inputed
u-COM to 16 times amplifiered through U4.
Voltage detectION circuit : U4
u-COM A/D through U4 pin 15 detected voltage.
BATTERY TEMPERATURE DETECTION CIR-
CUIT : U4
Battery temperature detection determined temper-
ature by ues of thermistor resistor variation of bat-
tery by U4.
