In this paper, we propose an auxiliary battery discharge prevention algorithm for semi-permanent use of auxiliary batteries for electric two-wheelers. The market for electric two-wheelers is growing due to the recent increase in delivery demand due to the COVID-19 and eco-friendly policies in India and Southeast Asian countries. In order to be competitive in the growing electric two-wheeler market, it is necessary not only to improve driving performance but also to develop various additional functions, so the use of auxiliary batteries in electric two-wheelers is essential and important. To prevent the auxiliary battery from being discharged, when the vehicle is not in use, the VCU wakes up periodically to check the auxiliary battery voltage. If necessary, it turns on the high voltage system to charge the auxiliary battery using the main batteries as a charging source. For this purpose, the ADC and RTC alarm wakeup functions of the VCU are utilized. In addition, data was calibrated considering the parasitic current of the entire system and the capacity and charge/discharge characteristics of the auxiliary battery. Finally, the effectiveness of the algorithm was validated through repeated charging and discharging tests in an actual vehicle.
