The electrolyte of an electric flat car lead-acid battery is as precious as blood in the human body. Once the electrolyte is lost, the battery dies. The electrolyte consists of dilute sulfuric acid and water. During the charging process, it is difficult to avoid the loss of water. Different charging methods have different water loss. The normal three-stage charging method, the water loss during charging is more than double that of the Colin Pulse mode! In addition to the natural life of the battery, there is also a loss of water life. If the battery loses more than 90 grams of water, the battery will be scrapped.
As the main power source of electric flat cars, batteries always affect the working efficiency of electric flat cars. Therefore, the daily maintenance of the battery has become an important means. In the process of using electric flat cars, many consumers often worry about lack of battery water and battery life.
In the constant current phase, the charging current is constant, the charging current increases rapidly, and the voltage increases. During the constant voltage charging phase, the charging voltage remains unchanged, the charging current increases, and the charging current decreases. When the battery is full, the current is lower than the floating charge conversion current, and the charging voltage drops to the floating charging voltage; during the charging phase, the charging voltage maintains the floating charging pressure.
The first stage of normal three-stage charging is constant current charging, which mainly considers the convenience of circuit design rather than the best battery performance design.
According to the analysis of the oxygen charging curve of the battery, the gas in the three-stage charging process is generally analyzed: the late stage and constant voltage charging at the beginning of constant current charging, the analysis of the current exceeding the critical gas curve, the cause analysis, and the battery life decreased. The current of the West German ultra-filter element will only increase the gas and temperature of the battery, and will not become the battery power, thereby reducing the charging efficiency. The occurrence of current bifurcation is very large, and it is more likely to cause imbalance in the battery pack.
