With the cumulative use of electric vehicles over time, battery parameters and functions may change. When the parameters of each battery in the battery pack are not consistent, there will be a phenomenon that one battery is fully charged while the other battery is not fully charged, which will only accelerate the aging speed of the battery in the long run. Therefore, it is necessary to set up a voltage equalizer to balance the battery voltage. The following is a detailed introduction to the role of battery equalizer.
The function of battery equalizer is introduced
Battery equalizer, also known as a battery balancer, is an electronic protection device that prevents voltage imbalance among battery cells from reducing the service life of a battery. When the voltage imbalance between battery cells, different cell charging and discharging speed is different. When a cell is charged, other cells are in the state of overcharge or undercharge, and overcharge or undercharge will damage the battery, resulting in reduced battery capacity and shortened battery life. The battery equalizer ensures the power balance among battery cells in real time, extending the battery service life by 5-30%.
The equalizer itself is a typical current/voltage balancing device. When charging, the equalizer is through the detection of voltage, found pressure difference through the current/voltage mutual energy transfer compensation. To achieve the battery voltage convergence of the balance purpose, prevent the battery overcharge and undercharge!
Installing a battery balancer has the following advantages:
(1) The performance and life of a battery pack with balanced voltage of each single cell is similar to that of a single cell, and there will be no huge difference;
(2) It can get rid of the battery failure caused by the battery imbalance. It is common for some batteries to be in a state of undercharge for a long time under plate vulcanization failure and overcharging resulting in battery water loss;
(3) the active balanced battery pack no longer needs the passive balanced high voltage overcharge, which can reduce the maximum charging voltage, which can make the battery lose less water, prolong the battery life, and greatly reduce the possibility of the battery thermal runaway;
(4) When a battery in the battery pack is damaged, it only needs to be replaced instead of the whole battery, which can save considerable costs. The equalizer will keep the old and new battery voltages in line and work properly.
