Battery Insulation Performance Analysis in Electric Vehicles for the Improvement of Battery Lifetime

The battery is the main component both as an energy provider and interface for several systems in electric vehicle. It has three important parameters: current, voltage, temperature that must be maintained can have a harmful reaction lead to overcurrent. also not overcharging or discharging too long because it cause damage affect its lifetime. Another error arise sensor failure due interference noise data reading. To prevent this problem, needs protection by means of isolation operating battery. In research, planning optimizing work was conducted designing process detection faults occurred batteries, particularly lithium polymer reach their more optimal good performance. Battery modeling needed parameter identification, Kalman Filter algorithm applied help reduce rate fault isolation. results overcurrent using were found quite accurate. isolation, discharge current 6A obtained from maximum limit 10 A, succeeded improving previous
