Analyze the balance of two kinds of charges in lithium-ion batteries Actively balance the existing literature describes several active charge balance methods that use energy storage elements to transfer energy. If a capacitor is used as a storage element, many switching elements are required to connect the storage capacitor to all batteries. It is more effective to use a magnetic field to store energy. The core of the circuit is the transformer. Passive balancing In traditional battery management systems, each battery is connected to a load resistor through a switch. The passive balancing circuit can individually discharge the specified battery, but this will only suppress the voltage increase of the highest voltage battery in the charging mode. In order to limit power consumption, a small current within 100 mA is usually used, which may lead to a charge balance for several hours.
