Now electric vehicles are becoming a more common means of transportation in our lives. Since the price of electric vehicles is generally higher than that of traditional bicycles, the service life has also become a concern for people. In fact, as one of the core components of electric bicycles, the service life of the battery largely determines the service life of the electric vehicle. Therefore, strengthening the maintenance of the battery will be able to extend the service life of the battery. It is understood that the batteries used by electric vehicles are lead-acid batteries, for the maintenance of lead-acid batteries, a series of suggestions are given below, including seven tips.

1. Charging

Lead-acid batteries have no memory, the reason for the rapid reduction in capacity is mainly the battery vulcanization and "water loss", "power loss" and other reasons, the battery is afraid of "power loss" undervoltage, the battery is often "power loss", the battery plate is extremely vulnerable to injury, In reality, up to 70% of the battery capacity of electric vehicles reduces the strain caused by the strong current (starting current) when the electrode plate is discharged (especially for electric motorcycles), and the strain of the electrode plate belongs to the physical damage of the battery, which cannot be repaired. Therefore, "Use the car every day and charge every day" to ensure that the battery has sufficient voltage at any time is inevitable.

2.Regularly add distilled water

Users generally think that maintenance-free batteries do not need to add water, in fact, this statement is wrong. Maintenance-free battery will generate heat in the process of charging and large current discharge, and there will be water evaporation, although the process of water evaporation is very slow, but over a long period of time, the amount of accumulated water evaporation can not be underestimated. Therefore, the battery should be replenished once every 6 months or so, so that the service life of the battery will be extended.

Can be used for battery water refill tools - battery water gun, small, lightweight, easy to carry, can effectively solve the manual water control is not accurate, too much or insufficient water and other problems, battery water gun has a key water refill function, water full induction stop, improve the safety of battery water, effectively extend the battery life, and low price of water gun, It can save high manual maintenance costs.

3.electric vehicle start

The starting current of electric vehicles is very large, especially the electric motor of high-power motor, the starting current is larger. Large current is very harmful to the battery plate, the better way is to ride like a bicycle before starting, and then start the electric vehicle power supply.

4. the battery discharge

After the battery is used for a period of time, there will inevitably be some active substances sinking, if the active substance is not activated in time, it is bound to have some impact on the capacity of the battery, therefore, when the electric vehicle is often used, it is necessary to discharge the battery once a quarter.

5.the charger

The charging process of the new battery is generally 6-8 hours, the charger will turn green after full charge, if the charging time is too long, it is necessary to check whether the charger voltage protection device is damaged, if the damage needs to be replaced in time, otherwise it is easy to charge the battery. In addition, the charger do not buy a fast charger, fast charging is also harmful to the battery plate.

6. Not used for a long time

The purpose of this is to prevent the battery from being placed for too long and causing battery vulcanization and "loss of power".

7. Cleanliness

If the battery is not cleaned in time, it is easy to affect the service life and power effect of the battery. Simply put, a battery is an electrochemical device that can convert chemical energy into electricity. To maintain the normal operation of the battery, the cleaning of the battery is essential. It is easy for oxidation reactions to occur between the pole and the chuck of this battery, and even the metal parts of the chuck head can be decomposed.

Maintenance-free battery, now most cars have begun to use, this battery does not need to add distilled water in use, the terminal will not corrode, less self-discharge, long life. However, if it is not checked in time, the owner of the battery is not clear when it is scrapped, which will also affect the normal work of the car.
