As we all know, batteries are the core components of electric vehicles. After a long period of use, there will be unbalanced battery packs. The main reason is that you need to pay attention to normal charging. Not charging, resulting in voltage imbalance. How to solve the problem of unbalanced battery voltage of electric vehicles? Let’s take a look together!
How to deal with the unbalanced voltage of electric vehicle battery pack?
First of all, we need to know that our electric vehicle batteries are used in series. When repairing the battery, we will always find many friends. The battery is a single “backward” battery. There are many reasons for this situation, including production reasons, raw materials and usage.
Aiming at the phenomenon of unbalanced battery discharge, the battery equalizer can solve this problem very well.
The battery balancer can compensate the battery in both directions. When the voltage difference of the battery in series exceeds 50mV, the battery balancer starts to work
When the battery equalizer is connected in series to charge the battery, it will reversely charge the high-voltage battery pack to the low-voltage battery, which has achieved the effect of the same voltage of the two battery packs, and keeps the two batteries discharged synchronously when the battery pack is discharged.
The battery balancer, also known as the battery balancer, is an electronic protection device that prevents the voltage imbalance between the cells inside the battery from reducing the service life. When the voltage between cells is unbalanced, different batteries charge and discharge at different speeds. When one cell is fully charged, the other cells are in an overcharge or undercharge state, and overcharge or undercharge will damage the battery capacity and shorten its life. The battery balancer can ensure the power balance between each battery compartment in real time, thereby prolonging the service life of the battery by 5-30%.
What are the advantages of installing a battery equalizer?
The battery equalizer is an energy transfer equalizer that can compensate the battery in both directions. When the voltage difference between the batteries connected in series exceeds 10 millivolts, the battery equalizer starts to work, and the current will flow from the battery with higher voltage to the battery with lower voltage. battery, eventually bringing the battery into balance. It can be connected to batteries connected in series for a long time, automatically maintains the balance state of the batteries, and requires no maintenance.
A battery without an equalizer will overcharge a good battery, cause capacity drop, electrolyte dry-up, etc., so that the stability and reliability of the battery cannot be guaranteed, and ultimately affect the operation of the entire battery pack system, resulting in excessive battery life. early damage.
The battery installed with the Lham equalizer, through active equalization, the battery with high voltage is transferred to the battery with low voltage for compensation, so as to achieve charging balance and make each battery fully charged, and finally realize energy transfer to extend the mileage of the battery and the battery pack. service life.
