What are the correct ways to charge the car?

At present, new energy vehicles have been widespread in our lives. Because the use of electric vehicles is environmentally friendly, fast in acceleration, low in vehicle cost, simple in structure, convenient in use and maintenance, and noiseless, it is popular with many people. So how does the car charge? Let's learn!

1. Connect the battery positive pole to the power supply positive pole and the battery negative pole to the power supply negative pole.

2. The initial charging is carried out in two stages: first, charge the electrolyte with the initial charging current until it emits bubbles, and the cell voltage rises to 2.3-2.4V. Then reduce the current to 1/2 of the initial charging current, and continue to charge until the electrolyte emits violent bubbles, and the ratio and voltage remain stable for 3 hours. The total charging time is about 45-65h.

The temperature shall be controlled at 35-40 ℃. After the initial charging, if the specific gravity of the electrolyte does not meet the requirements, distilled water or electrolyte with specific gravity of 1.4 shall be used for adjustment. Recharge for 2h after adjustment until the specific gravity meets the requirements.

3. After the first charge, the new battery often fails to reach its capacity, so the discharge cycle should be carried out. Discharge at a discharge rate of 20h (that is, discharge at a current of 1/20 of the rated capacity until the single cell voltage drops to 1.75V), and then supplement the charging current until it is sufficient. If the capacity is still lower than 90% of the rated capacity after a charging and discharging cycle, another charging and discharging cycle shall be conducted.

4. Pay attention to how to judge whether the new battery is fully charged, and judge whether the new battery is fully charged trilogy:

5. If the electrolyte "boils" and bubbles appear at the same time, it indicates that the charging is completed.

6. Measure the voltage of the single cell battery. If the voltage does not fluctuate within 3 seconds and reaches 2.7V, it indicates that the charging is completed.

7. Measure the relative density of the electrolyte. If the density does not fluctuate within 3h and reaches the maximum value, it means that the charging is completed.
