Abstract :
Lithium batteries are the main energy source of choice for electric vehicles in the future. However, when the battery is not used for a long time and is charged, there is a decrease in battery life when used due to a self-discharge current, due to a potential difference in voltage causing current to flow and energy being transferred to each battery. In this study, a method is proposed to protect the self-discharging of the battery by using a bypass diode that functions to transmit current and block the reverse direction by testing the battery connected to the load and not connected to the load using 4 batteries arranged in parallel, each battery connected to a multimeter to see the voltage and current. measured between batteries. The test results show the condition of the battery is not connected to the bypass diode, the current flowing between the batteries is measured because it has a voltage difference and when the battery is connected to the bypass diode, the current is 0 mA. So lithium battery protection can work well, namely to eliminate selfdischarge can work properly so as to maintain battery life when you want to use it and slow down the battery charging cycle.
