How to maintain the newly bought Emma electric car battery

Battery maintenance knowledge:

1. When the vehicle starts, do not power on, you should accelerate slowly and use the ankle to assist.

2. It is best to use the ankle to assist when climbing uphill or top wind, which is good for your battery and motor.

3. It is best to fill it all at once when charging, and then float for 1-2 hours after the red light is on.

4. Do not overload and drive excessively. When you find that the meter is running low when driving, you should use human riding.

5. Try to avoid sudden braking, frequent emergency braking consumes battery capacity; the faster the vehicle speed design, the greater the loss of the battery.

6. Prevent overcharging. Since over-charging will cause the corrosion of the grid to accelerate, a dedicated charger will be used for charging. Do not mix the charger due to battery formulation and process; do not charge the battery upside down.

7. Since exposure will affect the service life of the battery, avoid exposing the battery to sunlight.

8. Ensure that the battery is installed in a good position for heat dissipation. Keep away from heat when charging.

9. Diligent charging: Use lead-acid batteries to develop the habit of charging with the use, do not recharge the battery inside the battery.

There is no memory effect in the electric vehicle battery, and a reasonable charging opportunity should be selected according to the power usage:

When 100% runs out of electricity, the general charging time will be 8~10 hours, not more than 12 hours (it will affect the battery life). Of course, it is not recommended to use up the electricity every time. It is generally recommended. The battery is charged at about 70%, and the charging time is usually 6-8 hours.

For short-stroke users, it is recommended to charge once a week when the power consumption is 10% per day. When the electricity consumption is 20% per day, it can be charged once every three days. When the electricity consumption is 30% per day, it can be charged once every two days. When the daily electricity consumption is above 40%, it can be charged once a day to control the charging time, usually around 6 hours.

Develop a good car method, should not be over-discharged, should not over-charge, do a slow turn when driving start, try to keep moving at a constant speed, reduce brake start, not overload. Eliminate the misuse of charging with the use, you should choose a reasonable charging method according to the power consumption. Do not charge for a long time after discharge, and need to do regular maintenance and charge when it is not used for a long time.

When the electric vehicle is not used for a long time, it should:

1) The battery must be fully charged before being put on hold. Under the premise of full power, it is generally recommended to recharge the battery in 2 to 3 months. If conditions permit, it is best to charge it once every 1 to 2 months. Since the self-discharge of the lead-acid battery itself causes sulfation, if the power is not replenished for a long time, the capacity recovery will be difficult to affect the life.

2) When the electric vehicle is not in use, it should be stored in a cool and ventilated room. When the battery pack is fully charged, disconnect the load line to prevent the battery from discharging due to the no-load current.

First, the battery runs out and stops running.

Once the battery is used up, don't use it again. At this time, the battery has a great influence on the life of the battery. After the electricity is discharged, the substances that can be reacted have been exhausted. At this time, the discharge is continued, and the unusable reaction materials are used, and once they are used, they cannot be restored to their original traits.

Second, control the weight

Overloading is a situation that is often encountered in electric vehicles. The greater the weight of an electric vehicle, the more power it consumes. Therefore, the load of the electric vehicle must be within a reasonable range. Do not overload and increase the burden.

Third, avoid urgent emergency stop

When an electric vehicle is riding, it is not advisable to make an emergency stop. If the frequency is stimulated in a short time, the battery will be increased and the discharge efficiency will be increased. Therefore, during daily driving, avoid an emergency stop.

Fourth, keep driving at a constant speed

In the case of road and traffic conditions, the vehicle should maintain a stable driving speed. In the riding, if you need to accelerate, you should slowly rotate the speed control handle to avoid direct acceleration to the fastest gear. Try to avoid frequent braking and starting during riding. This extends battery and motor life.

Fifth, choose a flat road

The road surface is too bumpy, which will cause impact damage to the battery current discharge, reduce the battery capacity, affect the mileage and service life, and may cause damage to components in severe cases.

Sixth, prohibit battery loss storage

The battery must not be in a deficient state. The battery is often "depleted" and is prone to sulphation. The lead sulfate crystals are attached to the plates, causing damage to the battery plates. The longer the idle state is idle, the more severe the battery is damaged.

Seventh, accurately grasp the charging time

Accurately grasp the charging time. In general, the battery is charged at night, and the average charging time is about 8 hours. Overcharging or insufficient charging can cause the battery to heat up, lose water, etc., and reduce battery life. Therefore, due to reasonable charging, avoid harmful charging.

Eighth, control the ambient temperature

In the summer charging environment, it is best to find a low temperature environment, otherwise it is better to find a high temperature environment in winter. Since the battery is a chemical, the chemical reaction is of course required for temperature, and 25 ° C is the most standard reaction temperature.

Ninth, maintenance delay battery life

For about half a year, the battery is maintained once to extend the battery life. When the battery is used for a long time, the state of the battery will deteriorate sharply. If the battery is used for about half a year, the battery is still in adolescence. At this time, it is necessary to maintain the battery.
