Picture 9 is charger circuit of BP2002.When the longest charging time is 160 minutes,the timer acts.Thermistors RT is used to test the temperature of the battery charging and it is close to the surface of charging batteries. When the temperature of the battery is 60 ℃,the battery stops charging.When it is fast charging, the current flows through the Rs is 490 mA. It produces 98 mV voltage drop and produces 0.2V voltage drop on VD1.After fast charging,it compensates for the charging for 16O minutes and then it continuously supplements the charging in C/64 rate.
