　　(1) Hengliu charging method

　　The Hengli charging method is to use the method of adjusting the output voltage of the charging device or the method of connecting the series resistance with the battery to maintain the charging method of unchanged charging current. The control method is simple, but because the acceptable current capacity of the battery has gradually decreased as the charging process is proceeded. In the later stage of charging, the charging current is mostly used for electrolytic water, generating gas, and excessive gas.

　　(2) Constant pressure charging method

　　The voltage of the charging power maintains a constant value during the full charging time, and as the voltage of the battery end gradually increases, the current gradually decreases. Compared with the Hengliu charging method, its charging process is closer to the best charging curve. Quickly charging with a constant voltage. Due to the low battery power of the battery in the early stages of charging and the large charging current, the current will gradually decrease as the charging is proceeded. Therefore, the system only needs to control the system.

　　This charging method has very few electrolytic water, which avoids the battery overcharge. However, the current current is too large, which has a great impact on the life of the battery, and it is easy to curved the battery plate plate, causing the battery to scrap. In view of this shortcoming, the constant voltage charging is rarely used, and only when the charging power supply voltage is low and the current is large. For example, during the car operation, the battery is charged with a constant voltage charging method.

　　Phase charging method

　　This method includes the second -stage charging method and the third -stage charging method

　　① The second phase method uses a fast charging method combined with constant current and constant voltage. First, charging the voltage value of the constant current to the predetermined voltage, and then the constant voltage is changed to complete the remaining charging. Generally, the conversion voltage between the two stages is the constant voltage of the second stage.

　　② The third -stage charging method uses constant current charging at the beginning and end of the charging, and charging with constant voltage in the middle.

　　When the current is attenuated to the predetermined value, it is converted from the second stage to the third stage. This method can reduce the amount of gas to the least, but as a fast charging method, it is limited by certain restrictions.
