What is passive and active cell balancing?
Passive and active cell balancing are two battery balancing methods used to address this issue based on the battery’s state of charge (SOC). To illustrate this, let’s take the example of a battery pack with four cells connected in series, namely Cell 1, Cell 2, Cell 3, and Cell 4.
What is a passive charge balancing system?
The resistive method is called passive, and the capacitive or inductive methods are called active charge balancing systems. The passive method removes excess energy of the higher voltage cell using heat dissipation on the resistors or MOSFETs as a load . The active balancing circuit equalizes the battery cells at an average level.
What are the different types of battery balancing methods?
