Things you need to pay attention to when using electric four-wheel cleaning trucks in hot seasons

Do not expose to the hot sun. When the battery is operated in high-temperature seasons, there will be overcharging problems. The increase in temperature will increase the activity of each active material, and the reaction will be sufficiently violent. The oxygen evolution potential of the positive electrode and the hydrogen evolution potential of the negative electrode will decline. As a result, the response speed during charging is fast, the charging current is large, and the charging voltage required for charging is low. In order to prevent excessive charging voltage, the battery temperature should be reduced as much as possible to ensure good heat dissipation. Exposure to the sun at high temperatures will cause the temperature inside the power box to rise sharply, causing the battery temperature to rise, which will increase the internal pressure of the battery during charging and increase water loss, thus affecting the battery life.
Please remember to prohibit charging in high-temperature environments. The battery will generate heat during charging, thereby increasing the battery temperature. If the charging environment temperature is high at this time, it may cause the battery to lose too much water and dry out prematurely. The precipitated gas accumulates and is very likely to cause an explosion when encountering a heat source. At the same time, the power box becomes hot or the green light does not light up when the battery is charging. You should also go to various after-sales service points in time to check the battery and add fluid for maintenance.
Continuous rainfall will cause water to enter the electric four-wheel cleaning truck every day, resulting in a large increase in the number of repairs. Generally, electric four-wheel cleaning vehicles have waterproof measures for the controller, battery, motor, etc., but this does not mean that the electric vehicle can be soaked in the rain at will. If you often use an electric four-wheel truck on rainy days, it is easy to damage the vehicle. Therefore, on heavy rainy days, be sure not to park your car in a rainy place, because the battery of an electric car is very afraid of water. For minor water intrusion, just ventilate and dry it. If it is more serious, you need to go to a repair center. The motor and controller are easily damaged when water enters an electric four-wheel truck. Therefore, you must pay attention to the water depth. The electric four-wheel truck can run normally only when the depth of the water does not exceed half of it.
In the event of a heavy rainstorm, it is best not to use an electric four-wheel truck. In summer, you should also try to avoid sudden braking. When starting, you should start slowly. If possible, you can pause and wait for the speed to increase before continuing to accelerate. While the car is driving, try not to start and brake as frequently as possible. This not only avoids damage to the battery caused by high-current discharge, but also increases the driving range. Furthermore, the charging time in summer should not be too long. If the electric four-wheel cleaning truck is running with insufficient power, it must not continue driving but should be charged immediately. Secondly, if the vehicle is not used for a long time, it must be fully charged and then left alone, and the main circuit switch must be cut off. The battery must be recharged every one to three months.
When using an electric four-wheeled cleaning truck in the summer, try to pay attention to the safety of the battery. Because the weather is relatively hot, the battery has been generating heat during the use of the electric four-wheeled cleaning truck, so the safety hazard of the battery is also a This is a very big problem, and it is easy to cause spontaneous combustion and explosion of the battery. You must pay attention to the ventilation and heat dissipation of the battery, and avoid exposing the battery of the electric four-wheel cleaning truck to the sun.
