Can New Energy Vehicles Charge in High Temperatures?
2 Answers
New energy vehicles cannot charge in high temperatures. When charging new energy vehicles in summer, the following points should be noted: 1. Do not charge in high temperatures. Avoid charging under direct sunlight or immediately after driving in hot weather. 2. Stuffy environments are unfavorable for charging. Choose a cool and well-ventilated environment for charging, as overly stuffy conditions can negatively affect the charging process and damage the battery or reduce the charger's lifespan. 3. Control charging time and frequency. Adjust charging time and frequency based on actual conditions. Overcharging, excessive discharging, or insufficient charging can shorten battery life. 4. It is recommended to charge daily to keep the battery in a shallow cycle state. 5. If the charger plug continuously overheats for an extended period, immediately check for short circuits or poor contact. When charging the battery, if the charger plug continuously overheats for a long time, inspect it for oxides and clean them immediately before reinserting the charger.
I've researched electric vehicle technology for years and know that charging in high temperatures is fine, but you need to be cautious about temperature effects. Many new energy vehicles come with battery thermal management systems where fans or coolant operate to cool during charging. However, high temperatures can slow down charging speed, potentially extending it from one hour to two, and prolonged exposure can lead to reduced battery capacity. I've tested charging several times at temperatures above 35°C, and efficiency indeed dropped by 10%-20%. It's advisable to charge during cooler morning or evening hours or park in the shade to avoid direct sunlight. Some models, like certain Teslas, have built-in temperature monitoring that automatically slows the rate if temperatures exceed safe limits. This isn't just a charging issue—high temperatures also accelerate the aging of electronic components, affecting the vehicle's lifespan. EV owners should develop the habit of prioritizing slow charging in summer to protect the battery and extend its service life.
