Abstract

As of right now the development of electric vehicles is very rapid. This is supported by the transition from vehicles with fuel oil to electricity, the development of increasingly widespread electric vehicles, and the production of increasingly cheap batteries. Generally the battery used is a lithium-ion battery. But over time, the quality of the lithium-ion battery will be degraded so that the battery quality is not as early as its use. The causes of battery degradation are unbalanced cell in the battery pack. To overcome this problem, a reliable battery management system (BMS) is needed. In the design of the BMS to prevent the imbalance of the proposed battery voltage using the active method from cell to cell battery. BMS uses a microprocessor to process battery data, a microcontroller to control battery connecting switches, and a DC-DC converter circuit as well as a switched capacitor (SC). From the proposed design BMS is able to monitor the voltage of each battery directly, able to store automatic data on the database in the microprocessor, able to set the switch connected between the highest voltage battery to the lowest voltage battery, able to balance the battery with a voltage difference between batteries up to 0.0032 V, able to increase the capacity of the battery pack compared to the system without a balancing system up to 130 mAh , and the balancing system can increase the energy of the battery pack compared to the system without a balancing system to 10.363 Wh or 6.88%
