High-efficiency energy transfer battery equalizer technology

(Summary description)At present, a high-power, high-efficiency, real-time, dynamic transfer energy transfer battery equalizer technology has been successfully developed after many years.

Information

At present, a high-power, high-efficiency, real-time, dynamic transfer energy transfer battery equalizer technology has been successfully developed after many years. Incorporating the self-invented two-way synchronous rectification technology, which is a two-way synchronous rectification technology that does not require a synchronous rectification chip, not only the equipment cost is greatly reduced, but also the equalization current and equalization efficiency are greatly improved. A breakthrough in balanced technical indicators has been achieved, with the following characteristics:
  energy transfer battery equalizer
   1. The energy transfer battery equalizer has a large balance current range. A large equalization current means that the equalization speed is very fast. At present, the enhanced lithium energy transfer battery equalizer has realized that the relationship between equalizing current and voltage difference is about 1A/13mV. For example, when the voltage difference reaches 130mV, the equalizing current can reach about 10A, which is particularly conducive to high-speed equalization.
  
  2. The energy transfer battery equalizer has high equalization efficiency. High equalization efficiency means less power loss, higher utilization, and lower temperature rise of equipment.
  
  3. The energy transfer battery equalizer is dynamically balanced in real time. When the battery pack is in a static state, the voltage difference within the group can be controlled within 10mV or even smaller (depending on the setting of the reference voltage difference), and enters the micro-power standby detection state, whether the battery pack is in the charging state or discharging Status, once the voltage difference is detected to be greater than the reference voltage difference, it will immediately enter the high-speed equalization state. The advantages of real-time dynamic equalization are that the effective equalization time is long, the efficiency of the equalizer is high, and its unique pulse technology has good maintenance and capacity improvement effects on the battery , Has been tested by the application.
  
  Using a high-current, high-efficiency energy transfer battery equalizer can largely prevent overcharge, overdischarge and thermal runaway faults of the attenuated battery. Even if the capacity decay of the battery pack has formed the fact that the consistency has deteriorated, its decay speed can be reduced very well. By automatically forcing the voltage to maintain consistency, it can also increase the effective capacity of the battery pack to a certain extent and extend the battery pack’s The cycle life, in particular, significantly reduces repair and maintenance costs.
  
  The actual use effect of the energy transfer battery equalizer: use on the lead-acid battery pack returned to the factory by the customer of 24 strings of monomer 2V170Ah. Charge and discharge with standard 17A current. Without an equalizer, the discharge time after full charge is about 3h. During the discharge of 3 batteries, heat is serious, severe overdischarge, and the voltage value is lower than 0.5V, of which 1 battery is -0.1V , There has been a reversal. The voltage of 21 batteries ranges from 1.8V to 2.0V, and there is still a lot of electricity that has not been released; after using the energy transfer battery equalizer prototype in this article, under the standard charge and discharge parameters, the discharge time after several charge and discharge cycles Gradually extended to about 5.5h, the efficiency increased by more than 80%, the voltage of the three batteries after discharge is all above 1.5V, and the discharge voltage gradually rises, especially the serious problem of heat at the beginning, which has been improved, and the temperature is very low. Obviously, the voltage of only 4 batteries is around 1.9V, and the other batteries are around 1.8V, and the battery power is fully and effectively released.
