Battery manufacturers use low voltage constant voltage charging technologies, so-called low-voltage constant pressure charging, that is, traditional replenishment amounts, but it is.
Low voltage Hengfan charging is generally charged with a constant voltage of 2.25 to 2.35V using the ear battery. The battery is low. When the battery is low, the potential is low. At the beginning of the charging, the charging current is prevented from being too large, and the charging rectifier should be limited to limited Since flow characteristics, it is still in a constant current charging state. When a capacity is charged. The battery potential is rising. The charging current is gradually reduced. Battery manufacturers use this technology because this charging method is widely used due to the following advantages.
1 Charging current at the end of the charging is small. Therefore, the production of hydrogen and oxygen is extremely small. It can improve labor conditions, reduce the standard room standard, and is the way to apply,
2 The voltage is low in the final stage. When the power supply, the power supply such as the program, the power supply, which is widely used, can be powered, and normal charging can be carried out without departing from the load to simplify the operation, improve the reliability.
3 The maximum output voltage of the rectifier is small. The design weight of the umbrella can be reduced.
