Why Can't New Energy Fast Charging Reach Full Capacity?
1 Answers
Here are the specific reasons why new energy fast charging may not reach full capacity: Existence of Safety Redundancy: This is a setting by manufacturers for the battery, where approximately 80%-90% of the 100% battery capacity is actually usable. This ensures that the battery is not overcharged during use, nor is it excessively depleted while driving, significantly extending the battery's lifespan. Additionally, without safety redundancy, if the charging system malfunctions, overcharging the battery could lead to safety incidents such as explosions. Improper Driving: Since most pure electric vehicles have their battery packs located at the bottom of the vehicle, accidentally hitting the battery while driving can damage the battery pack, preventing it from charging fully. Inappropriate Charger: Using a charger that is not the vehicle's standard one, especially if the charger's maximum current is less than the battery's required value, can result in insufficient charging due to the lower current. This also prolongs the charging time, potentially damaging the battery due to excessive charging duration.
