The correct method for charging electric vehicles in summer is as follows:
1. Choose a suitable charging environment: Try to charge in a cool place or indoors, avoiding direct exposure of the battery and charger to sunlight. High temperature can accelerate the evaporation of electrolyte inside the battery, causing it to lose water and even swell. If it is necessary to charge outdoors, tools such as sunshades can be used to block the sunlight for the battery and charger, and sufficient space should be reserved for heat dissipation.
2. Pay attention to charging timing: After riding an electric bike, the battery will generate heat, so it is not advisable to charge it immediately at this time. You should wait for about half an hour for the battery to cool down before charging to reduce the risk of electrolyte evaporation. To avoid charging after the battery is completely depleted, it is recommended to start charging when there is still 20% to 30% remaining power to protect the battery from damage caused by deep discharge.
3. Proper use of charger: Use original or branded charger to ensure the quality and charging effect of the charger. Poor quality chargers not only have low charging efficiency, but may also cause damage to the battery. Follow the instructions for using the charger. When the green light of the charger lights up, it indicates that the battery is fully charged. At this time, you can continue charging for another half hour to ensure that the battery is fully charged, but you should avoid overcharging. Regularly check whether the connection wires and plugs of the charger are damaged. If they are damaged, they should be replaced in a timely manner to prevent safety hazards such as fires caused by poor contact or short circuits.
By following the above three steps, the safety of charging electric vehicles in summer and the lifespan of the battery can be ensured.
