With the repeated use of electric vehicles for a long time, the battery parameters will inevitably change. When the parameters of the batteries in the battery pack are different, there will be a phenomenon that some batteries are fully charged first while the other batteries are not yet fully charged. It will accelerate the speed of battery aging. Therefore, it is necessary to set up a voltage equalizer to equalize the battery voltage, which will be introduced in detail below.
Do Electric Vehicle Battery Equalizers Work?
The battery equalizer itself is a typical current and voltage type balancing device. When charging, the equalizer detects the voltage, finds the voltage difference, and compensates through the mutual energy transfer of current and voltage. To achieve the balance purpose of the convergence of each battery voltage, to prevent the overcharge and undercharge of each battery! The battery equalizer plays a very good role in protecting the battery and can prolong the service life of the battery.
Can EV battery balancing prolong battery life?
This problem should be discussed in several aspects. One is that if a series of voltages of the protection board reach the rated value, the charging will be stopped, so that the total voltage of the entire battery will not reach the rated value after charging. The second is that when a string reaches the minimum value during discharge, the discharge will also stop, which will affect the running time or mileage of the electric vehicle. The third is that the equilibrium is a limited equilibrium, and if the difference exceeds its set equilibrium value, it will have no effect. The last thing I want to say is that it is best to sort and inspect before production, and make a set of batteries with basically the same voltage and internal resistance, and the error should be within a balanced range.
Battery equalizers are still useful. If the battery voltage is unbalanced, it will cause your batteries to have high and low voltages. A battery with a low voltage will drain its energy very quickly. So use an equalizer to average their voltages. to increase mileage.
Battery equalizer function
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 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%.
In addition to the voltage equalization function, the battery equalizer also has the function design of undervoltage alarm and power display, allowing users to intuitively observe the battery status. The product is mainly used in the series environment of lead-acid batteries (VRLA). The equalizer is not affected by the battery connection mode, and can work in series or parallel.
Our equalizer is an active equalization system for lead-acid batteries that has been researched and developed for many years. It solves the problem of balanced charging and balanced discharge of battery packs such as electric forklifts, electric vehicles, and electric tractors, and effectively prolongs the mileage of batteries and battery packs. service life.
