Conventionally, it was popular way that the charge-and-discharge protection circuit for rechargeable Li-ion battery of electric vehicles only breaks circuit against the over-heating, overcharging and over-discharging. So, in this study, the authors proposed simple and convenient method of a protection circuit by using of PIC microcontroller, MOS FETs and power relays. Proposal protection control circuit surveys above mentioned electric failures simultaneously with A/D converter, voltage-dividing circuit and watch-and-control program. In the 16 series Li-ion modules, we made individual voltage checker per single Li-ion module. And we also attached detour circuit with power relay for each 4 series Li-ion modules in the 16 series Li-ion modules. As a result, proposal protection control of operating Li-ion battery system was confirmed from the bench-test.
