Information

The 100ah battery pack balance active balancing method uses an active reciprocating charge component, a voltage or current converter to make the power from one battery cell to another. These devices can be controlled by analog or digital. The two main categories of 100ah battery pack balance active balancing methods are charge shutting and energy conversion.

100ah battery pack balance

The 100ah battery pack balance method of charge shuttle includes a device that allows power to be discharged from a specific battery cell, stored, and then transferred to another battery cell.

Through the power conversion device, the battery balance uses an inductance or a transformer to transfer power from one or part of the battery cells to another or another part of the battery cells. There are currently two power converter modes: switching transformer method and shared transformer method.

The switching transformer method shares a switching topology as the flying capacitor method. The current I is taken from the entire battery pack and converted at the transformer T. The output of the transformer is corrected by the diode D and then transferred to the battery cell B. , And which battery unit is transferred to is determined by the setting of switch S. In this way, the whole device needs a set of electronic control device to select the target battery unit and set the switch S.

This method quickly equalizes low-power battery cells at the expense of consuming the energy of the entire battery pack. The disadvantages of this method are: complex structure, large number of components, and low efficiency due to magnetic loss and switching loss.

The only control part of the shared transformer 100ah battery pack balance is the conversion transistor of the main transformer, which does not require additional closed-loop control. The shared transformer device can quickly balance a group of multi-cell battery packs with minimal power loss. The disadvantages of this 100ah battery pack balance method are the complicated magnetic induction involved and the need for a large number of secondary loop rectifiers.
