First, the smaller the depth of discharge of the battery, the shorter the distance, the longer the battery's service life, and the longer the battery's service life. Second, the charging time should be determined according to the length of the mileage. The longer the charging time, the shorter the charging time, the shorter the charging time, the longer the charging time, the longer the charging time, the shorter the charging time, the shorter the charging time, the charging time The battery needs to be stored for a long time, usually charged once a month. (4) High current discharge will damage the battery to a certain extent, so when starting uphill negative wind, use the pedal to help the battery. (5) Use the prepared charger to avoid high temperature and humidity in a cool and ventilated place. Do not let water enter the charger to prevent electric shock.

　　The lead-acid battery of the second electric car has no memory effect. According to the electricity consumption, the reasonable charging time is 1100%. Not more than 12 hours (that is, the impact on battery life) is not recommended to charge about 70% each time the power is used. At this time, the charging time is usually 6 hours and 8 hours. If you are on a short trip, you can charge it once a week at 10% per day. The daily electricity consumption is 20%, and it can be recharged every three days. 30% of the electricity per day can be charged once every two days. When the daily power consumption exceeds 40%, it can be charged for about 6 hours a day. If the battery is not charged for a long time after discharging, it should be maintained and charged regularly.

　　If electric vehicles are not used for a long period of time, they should be rechargeable: 1 The battery must be charged before shelving, and it is usually recommended to replenish the battery within 2 to 3 months. If possible, it is best to charge it once a month. When electric vehicles are not in use, they need to be stored in a ventilated and cool indoor battery pack, and then the load line is disconnected due to the self-discharge of the lead-acid battery. If it is not replenished for a long time, it will cause difficulty in capacity recovery, which will affect the life expectancy.

　　Three details: The charger mode is a three-level charging mode. When 100% power is consumed, the charging time is 8 hours. Do not exceed 12 hours (affecting battery life) Of course, it is not recommended to charge each time it is used. The charging time is usually 6 hours or 8 hours.

　　If you are on a short trip, it is recommended that you charge 10% per week. The daily electricity consumption is 20%, and it can be recharged every three days. 30% of the electricity per day can be charged once every two days. When the daily power consumption exceeds 40%, it can be charged for about 6 hours a day.

　　Many electric vehicle users always think that the charger will be full of the green light of the self-stop charger, without the need for long-term charging. This is a wrong idea, the green light after the charger is still charging.

　　When the battery is charged, the battery is heated, and the leaking battery swells and deforms, which is why the battery is damaged by more than 75% of the batteries.

　　After long-term use, the parameters of the internal electronic components will cause the output voltage to change the charging suspension voltage. At this time, the charging light is not allowed to turn green.

　　Don't come back every day to recharge, so it's easy to charge. The battery life is calculated based on the number of recharges, even if the power is exhausted, even if the battery power consumption is about 30%, charging is the best.
