As we all know, the battery as the core part of the electric vehicle, after a long time of use, there will be battery pack imbalance, mainly the usual charging needs to pay attention to, as far as possible after a one-time full use, avoid repeated cycle charge and discharge, or a long time without charging, resulting in voltage imbalance. How to solve the problem of electric vehicle battery voltage unbalance? Take a look!
How to deal with electric vehicle battery voltage imbalance?
First of all, we need to know that our electric vehicle battery is used in series, in the repair of the battery will always find a lot of friends there will always be some, the battery is a single “backward” battery exists. There are many reasons for this situation, including production reasons, raw material reasons and use reasons.
Battery equalizer can solve the problem of unbalanced discharge of battery.
1. The battery equalizer can compensate the battery bidirectional. When the voltage difference of the series battery exceeds 50mV, the battery equalizer starts to work.
2. When charging batteries in series, the battery equalizer reversely charges the low-voltage battery from the high-voltage battery string to ensure that the voltage of the two battery strings is consistent. When the battery strings discharge, the two batteries discharge simultaneously.
This section describes battery Equalizer
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 battery charging and discharging speed is different. When a battery cell is charged, other battery cells are in the state of overcharge or undercharge, and overcharge or undercharge will damage the capacity of the battery and shorten the life. The battery equalizer ensures the power balance among battery cells in real time, extending the battery service life by 5-30%.
What are the advantages of installing a battery equalizer?
A battery equalizer is an energy transfer equalizer that compensates both batteries. When the voltage difference between batteries connected in series exceeds 10 millivolts, the battery equalizer starts to work. Current flows from the battery with a higher voltage to the battery with a lower voltage, and the battery finally reaches balance. Can be connected in series connected battery for a long time, automatically maintain the balance state of the battery, no maintenance.
If an equalizer is not installed on the battery, the good battery will be charged, the capacity will decrease, and the electrolyte will dry up. As a result, the stability and reliability of the battery cannot be ensured. As a result, the running of the entire battery string system is affected, and the battery service life is damaged prematurely.
The battery equipped with Lianhong equalizer transfers the power of the battery with high voltage to the battery with low voltage to compensate through active balancing so as to achieve the charging balance and make each battery full, and finally realize the energy transfer to extend the battery mileage and the service life of the battery pack.
Lianhong battery equalizer is a lead-acid battery active balancing system devoted to research and development for many years to solve the problem of balanced charging, balanced discharge of battery packs such as electric forklift, electric vehicle, electric tractor, effectively extend the range of battery life and battery packs.
