In recent years, lead-acid batteries have been widely used in industries such as railways, electric power, and communications. Lead-acid batteries have the advantages of convenient use, stable performance, and less maintenance, and are welcomed by users. However, during use, lead-acid batteries are used as backup Most of the power supply is unbalanced. How to solve the phenomenon of unbalanced charging of the battery? Please listen to the explanation by the editor of Lham!
Floating charging state is the mode in which the charger and the battery pack run side by side on the DC bus. During normal operation, the charging equipment mainly supplies the normal DC load. At the same time, it also supplements the self-discharge of the battery with a small current. Power supply, when the DC power supply equipment fails, the battery will provide power to the load to ensure the normal operation of the load.
However, when the battery pack is working on float charge, the voltage of the single battery cells is unbalanced due to some reasons, which leads to the deterioration of the battery pack. If the battery pack is not treated in time, it will directly affect the life of the whole pack of battery packs. In order to avoid the continuous deterioration of the battery, the manufacturer of Lham has launched a battery equalizer to keep the unbalanced battery in balance, which is a necessary product for extending the service life of the battery pack.
How to solve the unbalanced battery voltage of electric vehicles?
Aiming at the phenomenon of unbalanced battery discharge, the battery equalizer can solve this problem very well.
1.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
2.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 is also called the battery balancer, which 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 the battery compartments is unbalanced, the charging and discharging speeds of different battery compartments are different. When one battery compartment is fully charged, the other battery compartments are in the state of overcharging or undercharging, and overcharging or undercharging will damage the battery and cause the battery capacity to drop. Shortened lifespan. 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%.
