① Analyze the power consumption of the vehicle and control the terminal voltage of the generator within the specified range. For example, long-distance vehicles that often drive in the daytime will charge more and discharge less. To prevent the problem of overcharge, appropriately reduce the charging current. For short distance vehicles running at night and vehicles starting frequently, to prevent excessive discharge, try to increase the charging current appropriately, and fully charge when parking for next use.

②要注意车辆行驶的气温条件。在寒冷地区，要注意对蓄电池的保温工作，合理选择电解液的密度，使其保持在充足电的状态，加注蒸馏水要在充足电时进行，以防结冰。在启动前应对发动机进行预热，摇动发动机合理使用起动机，每次启动时间不宜超过5S，再次启动应间隔15S以后，连续两次启动不着，应排除故障后再启动。所以在寒区，由于蓄电池容量的下降，过量放电的问题尤为突出。

② Pay attention to the temperature conditions of the vehicle. In cold areas, pay attention to the thermal insulation of the battery, reasonably select the density of electrolyte to keep it in a fully charged state, and fill distilled water when it is fully charged to prevent icing. Before starting, the engine shall be preheated, the engine shall be shaken, and the starter shall be used reasonably. Each start time shall not exceed 5S. After another start, the interval shall be 15s. If it fails to start for two consecutive times, it shall be started after troubleshooting. Therefore, in cold regions, due to the decline of battery capacity, the problem of excessive discharge is particularly prominent.

③充电时蓄电池内进行着激烈的电化学反应。在临近充电终了时，由于有电解水的作用，蓄电池会放出大量的氢气和氧气。氢和氧是易燃气体，当遇到明火时，会激烈燃烧，甚产生爆炸，引起火灾。另外，在充电间的空气中还含有硫酸酸雾，因此设置的充电间须符合两点：

③ During charging, there is a fierce electrochemical reaction in the battery. Near the end of charging, the battery will release a large amount of hydrogen and oxygen due to the action of electrolytic water. Hydrogen and oxygen are flammable gases. When encountering open fire, they will burn violently, even produce explosion and cause fire. In addition, the air in the charging room also contains sulfuric acid mist, so the charging room must meet two points:

通风良好，

Good ventilation,

在充电间内严禁有火源，充电过程中严禁用高率放电计检查单格电池的电压，否则极易引起气体爆炸事故

No fire source is allowed in the charging room. It is forbidden to check the voltage of single cell battery with high rate discharge meter during charging, otherwise it is very easy to cause gas explosion accidents
