Charging method of lithium-ion battery PACK
The charging method of lithium-ion battery PACK: If the battery cells are selected, assembled, packaged, and installed conservatively, the charging process can be tested to determine whether the content and pressure difference of the product can pass.
The consistency between battery series and parallel units needs to be specially considered in battery pack. Only with good consistency in capacity, state of charge, internal resistance, self discharge, etc. can the capacity of the battery pack be fully utilized and released. Poor consistency can seriously affect the overall performance of the battery pack, and even cause overcharging or overdischarging, resulting in safety hazards. A good composition scheme is an effective way to improve monomer consistency.
Lithium ion batteries are constrained by environmental temperature, and high or low temperatures can affect battery capacity. The cycle life of batteries working under high temperature conditions for a long time may be affected, and if the temperature is too low, the capacity may not be fully utilized.
The discharge rate reflects the high current charging and discharging ability of the battery. If the rate is too small, the charging and discharging speed will be slow, which will affect the testing efficiency; If the rate is too high, due to the polarization and thermal effects of the battery, the capacity will decrease, so it is necessary to choose an appropriate charge and discharge rate.
discharge rate
The discharge rate is a crucial indicator for power type power batteries. The high rate discharge of batteries is a test for positive and negative electrode materials and electrolytes. For the positive electrode material lithium iron phosphate, its structure is stable, the strain during charge and discharge is small, and it has the basic conditions for high current discharge. However, the disadvantage is that the conductivity of lithium iron phosphate is poor. The diffusion rate of lithium ions in the electrolyte is the main factor affecting the discharge rate of the battery, and the diffusion of ions inside the battery is closely related to the structure and electrolyte concentration of the battery. The available capacity of the battery decreases with the increase of discharge current.
