About This Product
■Maintains cell voltage balance to extend battery life Suitable for 24V140Ah / 200Ah / 300Ah packs Active cell balancer for 8-cell battery packs
A cell balancer is a device that only has the cell balance function of BMS (battery management system). Without using an expensive BMS, it maintains the voltage balance of each cell at all times (during charging, discharging, and standing still) in a battery pack with two or more cells connected in series, preventing overcharging and overdischarging of the cells and increasing durability. This improves the performance and enables longer-term use.
There are two types, one for 4 cells and one for 8 cells.For 8 cells or more, multiple cell balancers can be connected to work together to maintain balance.
・The upper and lower voltage limits of the entire battery pack are managed by the connected charging/discharging equipment.
- Does not support parallel connection of 2 battery cells
・3 cell balancer performs balance function independently without connecting to charger or discharge equipment
■If used for a long time without cell balance
A slight voltage difference may be amplified and the balance may be disrupted, leading to overcharging or overdischarging.
■Active cell balance
The voltage difference between cells is constantly corrected to maintain the balance of each cell voltage.
Here's the great thing: Benefits of active cell balance
■Passive cell balance method
In the case of the passive cell balance method, the power of cells that reach a voltage higher than the reference value during charging is released as heat to achieve balance, which results in power loss and balances only during charging. Therefore, at the end of discharge, there is a risk that the cell balance will be greatly disrupted and overdischarge will occur.
Furthermore, if they are connected in parallel, the balance will be further disrupted, and there is a risk that some cells will over-discharge and begin to deteriorate very early in the discharge process. (In order to make this situation more difficult to understand, some sales companies go out of their way to package battery packs in cases that make it difficult to measure cell voltage.)
■Active cell balance method
Active cell balancing is a balancing method in which power flows from cells with high voltage to cells with low voltage, so there is little power loss, and the balance function is maintained not only during charging but also during discharging and while standing still without charging or discharging. I will.
