With the repeated use of electric vehicles for a long time, battery parameters will inevitably change. When the parameters of all batteries in the battery pack are different, there will be a phenomenon that one battery is fully charged while the other battery is not, which will only accelerate the aging speed of the battery for a long time. Therefore, it is necessary to set a voltage equalizer to balance the battery voltage, the following is a detailed introduction.
Does electric car battery Equalizer work?
Battery equalizer itself is a typical current and voltage balancing device. When charging, the equalizer detects the voltage difference and compensates by the mutual energy transfer of current and voltage. To achieve the battery voltage convergence of the balance purpose, prevent the battery overcharge and undercharge! The battery equalizer protects the battery and prolonging its service life.
Can electric vehicle battery do balance to extend endurance?
This problem should be divided into several aspects to talk about, one is that the protection board in the identification of a series of voltage to reach the rating, will let the charging stop, so that the total number of battery charging after the completion of the total voltage up to the rating. Second, when the discharge reaches the lowest value, it will also stop discharging, affecting the time or mileage of the electric vehicle. Third, the equilibrium is a finite equilibrium, if the difference exceeds its set equilibrium value also has no effect. Finally, I would like to say that it is best to check the voltage and internal resistance before production, and make a group of batteries with the same voltage and internal resistance. The best error is within the range of equilibrium.
The battery equalizer is still useful. If the battery voltage is not balanced, it will cause your battery to have high voltage and low voltage. A low-voltage battery will quickly run out of energy. So we use an equalizer to average their voltages. To increase the range.
Battery equalizer function
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%.
In addition to voltage balancing function, battery equalizer also provides undervoltage alarm and power display function, so that users can intuitively observe the battery status. The product is mainly used for lead-acid battery (VRLA) series environment, equalizer is not affected by battery connection mode, can work in series or parallel.
Lham battery equalizer is a lead-acid battery active balancing system dedicated to research and development for many years. It solves the problem of balanced charging and discharge of electric forklifts, electric vehicles, electric tractors and other battery packs, and effectively extends the range of battery life and battery packs.
