Lead-acid batteries have been widely used in various fields. Batteries are generally used after a number of batteries are in series. Even if the consistency of the batteries is better after screening before a group, differences will appear after a period of use. To ensure battery voltage consistency, an equalizer must be used to improve battery performance and service life.

There's active equilibrium and passive equilibrium, what's the difference between the two?

Active equilibrium (lossless equilibrium)

Active balancing is carried out in the way of energy transfer, which transfers the high energy of a single cell to the low energy of a single cell, so as to realize the balance of the whole group of voltage. In the process of transfer, almost no energy loss is involved.

Passive equilibrium

Passive balancing usually discharges batteries with a high voltage by means of resistance discharge to release electricity in the form of heat to balance the whole group of voltages and obtain more charging time for other batteries.

The necessity of battery equalizer

When two batteries with different voltages are connected in series, the current does not change due to the addition of voltages after being connected in series. Therefore, when discharging, the battery with low voltage will preferentially finish discharging, and because the total voltage of the battery pack is still too high, there will be excessive discharge of the low-voltage battery, and eventually damage. When we add an equalizer, the high-voltage battery will charge the low-voltage battery in reverse, so that the voltage of the two batteries is the same. When the battery string is discharging, keep the two batteries discharging simultaneously to maximize the battery capacity and extend the service life.

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 guaranteed. As a result, the running of the entire battery string system is affected, and the battery service life is damaged prematurely.

A battery equipped with an equalizer transfers the power from a battery with a high voltage to a battery with a low voltage to compensate through active equalization to achieve charge balance so that each battery is fully charged, and finally realizes energy transfer to extend the battery mileage and the service life of the battery pack.

How does a battery Equalizer improve battery life?

Lham battery equalizer is a kind of electronic protection system to prevent the voltage imbalance between the battery cells in the battery from reducing the service life. 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%.

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.
