Abstract:

Electrical vehicles are future of auto mobile industry. Lot of conversion happen form ICE vehicles to electric vehicles since few years. IC engine are well proven and still running without any fails. But electric vehicles face lot of problems especially from battery fire accidents. EV batteries have density energy storage chemicals and causes fire while charge and discharge. Some kind of EV batteries getting fire when external environment is high temperature. Also there are several reasons to cause battery getting fire. To avoid and suppress this problem, we suggest smart BMS that will protect battery from fire and charge monitoring. The proposed project title is EV BMS fire protection and charge monitoring. Two buttons for selecting fast and slow charging of battery. Based on selection, battery will charge fast and slow by current control. If more current allow then battery will charge fast and vice versa. Third button is for discharging battery by enabling load. Here we used motor as load. If battery gets fully charged then charging will disconnected automatically. While charging or discharging if battery temperature increased then load will disconnect automatically. All this operation information like voltage, current and temperature values will be displayed on 16×2 LCD display.
