Lithium battery charging and discharge method.best portable power station

　　The problem that needs to be solved is the charge and discharge method of lithium batteries to prevent lithium batteries from charging at low temperatures and separate lithium metal. Lithium battery low -temperature charging method: The battery processing system detects the battery temperature in real time. The battery processing system reads a preset rule. The rules define multiple continuous thermal insulation. Each thermal label corresponds to a charging intercept voltage.

　　The battery charging and discharge method determines the appropriate charging interception voltage and discharge intercepting voltage according to the battery does not attack the "lithium crystal" thermostat. When charging constant current, when the battery voltage rises to the charging off voltage and the constant voltage is charged, the temperature of the battery is detected in real time. Secondly, during the charging process, the temperature of the battery gradually increases, the battery temperature reaches another temperature label, then the corresponding charging deadline The voltage is also increased. According to the new charging cutter voltage, it is executed until the battery is fully charged. The battery charging method can further determine the appropriate charging current according to the temperature standard.
