6 FAQs about [Bypass Charge Equalizer for Series Battery Pack]

How does a bypass equalizer work?

The bypass equalizer relies on a series of switches, which only needs to change the energy flow path in a battery pack. Definitely, the switch modes of the bypass equalizer should be carefully designed to manage the weak or strong cells. All possible switch modes compose the balancing strategy for the bypass equalizer.

What is a series battery pack equalizer?

Despite a reduction on the voltage stress on the electronic devices, the proposed equalizer requires a multi-winding transformer for each fly-back DC-DC converter. Therefore, the equalizer has a large volume and complex topology. A series battery pack equalizer is developed in using the PWM control and C2C.

Why does a battery pack need an equalizer?
