3BHB003688R0101 is a voltage stabilizing power supply consisting of LM317 and transistor 2SA1186. The output voltage is continuously adjustable from 2-30V, and the load current can reach 5A. If several more 2SA1186 are connected in parallel, the output current can be higher, provided that there are sufficient heat sinks or fans.
R21 is an NTC thermistor with a resistance value of 18K.
M1 Fan Motor
RLY1 12V relay current 10A

3BHB003688R0101 can analyze the working principle of this circuit diagram
A battery repairer for electric vehicles sold in the market, but its effectiveness is not significant after use. After analyzing its circuit composition, it was found that its repair uses high-voltage and high-frequency pulses through oscillation circuits and self induction boost coils. Due to frequency limitations, it is not possible for the self inductance boost coil to be very large, but for 3BHB003688R0101 with small internal resistance, the amplitude of the high-voltage pulse that can be generated under static conditions becomes very low when applied to the battery. So the repair effect on the battery is not significant.
