Maintenance method of electric classic car

1, charge the battery evenly every three months to half a year, each time charging 1-2 hours;

2. Check the water level;

3. When the voltmeter indicates the yellow area or the ammeter shows the second grid, it must be charged. Excessive discharge is strictly prohibited. Keeping the battery in a state of charge above 70% is conducive to prolonging the battery life;

4. Cover the cover of the exhaust port of the electric classic car tightly before charging;

5. Be familiar with and abide by the operating instructions issued by the charger manufacturer;

6. Don't overcharge. Overcharging will lead to a large amount of gas (water consumption) and battery heating and aging;

7. Don't owe money. Insufficient charging will lead to battery passivation;

8. Do not charge the frozen battery;

9. Avoid charging the electric classic car at a temperature above 120℉(49℃);

10, the electric classic car should be charged after use every day;

1 1, lead-acid battery has no memory effect, so it does not need to be completely discharged before charging;

12, keep the charging place well ventilated, away from sparks or flames;

13. Make sure that the charger of the electric classic car is trouble-free (the voltage setting is correct). 1. When the electric hand brake fails, the adjusting bolt at the joint of the front and rear hand brake pipes can be adjusted;

2. Regularly check the oil content of the brake oil pot of the electric classic car. When the amount of oil in the oil pot is less than 1/3, it must be refueled immediately;

3. If the brake is soft or ineffective, adjust the brake clearance in time to exhaust the air in the brake pipeline;

4. Brake deviation can adjust the gap between the brake shoe and the brake drum in the brake;

5. Regularly check the state of each fixed point between the brake pipeline and the frame of the electric classic car, and take protective measures in time when it is found that it falls off or there is friction between the pipeline and the frame;

6. Always check the electric classic car to see if the connecting device of the brake line is loose and worn. Adjusting the brake of the electric vehicle can directly adjust the thread on the brake hook connected with the brake pedal. Analysis of the reasons why electric classic cars can't be charged;

1, failure phenomenon:

After starting, the ammeter pointer returns to the correct position too fast during driving, or the battery temperature of the electric classic car is too high, and the ammeter pointer still points above +5A after driving for a long time.

2. Reason for failure:

(1) The battery of the electric classic car is strained.

(2) There is an internal short circuit fault.

(3) The active substance on the electrode plate falls off, resulting in too small capacity.

(4) Vulcanization of polar plate or hardening of negative plate.

3, fault diagnosis and elimination:

For the fault diagnosis of electric classic car batteries, it is necessary to make a judgment based on the comprehensive analysis of fault phenomena and their uses. If the battery of an electric classic car is used for more than one year, the above phenomenon occurs. Generally speaking, the battery of an electric classic car has been exhausted and should be replaced with a new one. If the battery temperature of the electric classic car is on the high side, the ammeter pointer still points to above +5A after long-term driving, which can be detected by a high-rate discharge meter. If the measured voltage of a battery is lower than 1.5V, it means that the battery has a short circuit fault and should be disassembled for maintenance. I. Driving and services

Immediately start the accident emergency plan, organize rescue and emergency repair, prevent the accident from expanding, reduce personal injury and property loss, and immediately report to the Emei Mountain special equipment safety supervision and management department and relevant departments.

(3) Seriously investigate the cause and process of the accident, report in accordance with the Regulations on Safety Supervision of Special Equipment, deal with relevant personnel, and sum up experiences and lessons. When the battery of an electric classic car needs to be replaced, it should be fully charged. The driver drives an electric classic car on a flat secondary road and turns off the power supply knowing that the battery voltage is less than the undervoltage value. Under the above conditions, the obtained riding mileage is usually called the driving range of electric classic cars. It is a comprehensive index, which is related to the quality of battery, motor, controller and charger, the matching quality of the system and the assembly quality of the whole vehicle.

As far as batteries are concerned, electric classic cars require long battery life, high specific energy (that is, the longest distance that can be driven by one charge) and high specific power (that is, the ability to accelerate climbing). According to the inspection requirements of the electric classic car industry, it is known that the lead-acid batteries with 36v and 12Ah must be discharged at a current of 5A to a voltage of 3 1.5V, and the discharge time should not be less than 2h. For such a battery capacity, with reference to the electric sightseeing bus power consumption 15Wh/km, the theoretical grouping of the designed electric classic car is about 130Km. But the new battery can also meet the driving range of 150.

In actual use, how many kilometers can the battery travel after being fully charged? It is often related to many factors, such as the efficiency characteristics of the motor, the capacity of the battery, the thermal life and so on. In addition, due to the limited storage capacity of the battery, it consumes too much energy too quickly, and once it is charged, it will greatly reduce the driving range. For example, an electric classic car using 36v, 12Ah lead-acid battery can travel from 120 to 140km when the speed u is less than or equal to 30 km/h, and the driving range after one charge will be less than 100km when the speed u is 40km/h.. Therefore, no matter from the perspective of safety or technology, the speed of electric classic cars should strictly follow the relevant national standards, and high speed should not be pursued unilaterally.

The battery pack of an electric classic car is generally composed of three or four single cells connected in series. If the terminal voltage of each battery is different, the battery with high terminal voltage will be overcharged first. At this time, because the voltage value of the battery pack does not reach the constant voltage state, the first battery will be damaged due to overcharge. The damaged battery will cause other batteries to be damaged due to overcharge because of low voltage.

Therefore, the voltage error of each battery in the battery pack should be controlled within 0.03 V, and the internal resistance voltage and discharge time of the battery are the same or similar, which is also a prerequisite for maintaining the effective driving range.
