What issues should be noted when using electric vehicles in high-temperature environments?

1、 Charging safety: avoid high temperature periods and enclosed environments

Prohibit charging during high temperature periods

When electric vehicles are charged at high temperatures, the internal chemical reactions of the battery intensify, which can easily cause electrolyte evaporation, sulfate crystallization on the electrode plates, and even lead to battery bulging and deformation. It is recommended to charge during cooler periods such as early morning or evening to avoid direct sunlight at noon.

Stay away from confined spaces

Do not charge indoors, in corridors, or in enclosed garages. Poor battery heat dissipation in high temperature environments may cause spontaneous combustion due to heat accumulation. A ventilated and cool place should be chosen to ensure that the charging environment temperature does not exceed 30 ℃.

Control the charging duration

High temperature can accelerate battery charging speed, but overcharging (such as exceeding 8 hours) can lead to overcharging and shorten battery life. It is recommended to use a smart charger or timed socket, which will automatically power off when fully charged.

Avoid charging immediately after cycling

After riding an electric bike, the battery temperature is high. If charged immediately, it will intensify the heat accumulation, causing the electrolyte to boil or even the active substances to fall off. It is recommended to let the battery cool down for 30 minutes to 1 hour before charging.

2、 Battery protection: prevent overheating and overdischarging

Avoid over discharging the battery

High temperature can accelerate battery capacity degradation, and if the battery is left idle for a long time after being fully charged, it may cause the battery to sulfide. It is recommended to maintain the battery level between 20% and 80% to avoid deep discharge.

Check the battery status

Regularly check whether the battery casing is bulging or leaking. If any abnormalities are found, immediately stop using and replace the battery.

3、 Parking management: reduce exposure to sunlight and water

Avoid prolonged exposure to sunlight

High temperature exposure to sunlight can accelerate the aging of electric vehicle plastic parts, fade the paint, and even cause high battery temperature and malfunction. It is recommended to park in a cool place or use a sunscreen cover.

Drive cautiously through water

After the rainstorm in summer, there is a lot of water on the road, and water ingress into electric vehicle motors, controllers and other components may cause short circuits. It is recommended that the water depth should not exceed half of the tire, and the vehicle should be checked and dried in a timely manner after driving.

4、 Daily maintenance: Regular inspection and standardized use

Check the wiring and brakes

High temperature can easily cause aging and poor contact of the circuit. Regularly check whether the circuit contacts are loose to avoid short circuits and fires. At the same time, check whether the brake system is sensitive to ensure driving safety.

Use original accessories

Chargers, batteries, and other accessories should be matched with electric vehicles to avoid abnormal charging caused by the use of non original or inferior products.
