Which battery can be free of refilling fluid?

How can electric vehicle batteries be used longer?

Battery charging operating temperature. The best battery charging environment for battery car batteries is 25 degrees. Therefore, in the winter battery charging should be placed in a warmer area battery charging, so as to improve the battery capacity of the battery. But it is not recommended that everyone put the battery car in the house to charge the battery to prevent a safety accident.

Try to avoid applying fast charging. In the case of normal battery charging, the battery of an electric vehicle needs about 8 to 10 hours to charge the battery, and a fast charge only takes half an hour to fill up the battery. Such fast charging is very harmful to the rechargeable battery. Will reduce the life of rechargeable batteries.

Charge the battery immediately. In winter, the average temperature drops and the battery capacity is depleted very quickly. When the battery capacity is about 20% or so, immediately charge the battery car. In the long run, you will find that the rechargeable battery is much more durable than before.

Which battery can be free of refill?

Because of the advantages of the maintenance-free battery, the use of lithium battery electrolyte is very small, and there is basically no need to fill up with distilled water during the service period. It also has the characteristics of shock resistance, heat resistance, small size, and low self-discharge. The service life is generally twice that of a normal battery. There are also two types of maintenance-free batteries on the sales market. After the lithium battery electrolyte is added at the time of purchase, there is no need for maintenance in the application (plus replenishment liquid); the other is that the rechargeable battery itself has a lithium battery already added in the original factory. The electrolyte is sealed and the customer cannot add replenisher at all.

There are four ineffective methods of positive electrode erosion, lack of water, uncontrollable heat, and potassium thiocyanate. Among them, the positive electrode grid is etched due to the aluminum alloy production process. The etching rate is very slow. It is generally 10-15 years. The design of multiple overflow valves is unscientific for the way of water shortage, open it; the switch power supply charges the battery equally; the temperature is too high, among which high temperature is the key element. High temperature will accelerate the battery water shortage rate and reduce the battery capacity. Standard, when the battery operation rises by 10°C. The service life is 50%. Uncontrollable heat means that the heat generated by the battery during battery charging is not released immediately. A positive gratitude feedback is generated between temperature and chemical changes. Uncontrollable and uncontrollable heat is destructive to the battery. The battery case is deformed. The serious situation leads to the battery, and the heat cannot be controlled because the temperature of the host room exceeds 45℃, the battery charging voltage is high at high temperature (no temperature compensation function), and the current exceeds the design value (exceeding 25C10).
