What does BYD EV limited mean?
3 Answers
EV function limitation generally means the high-voltage system of the car is faulty. The specific situations and impacts are as follows: Situations when the fault occurs: The EV function limitation only occurs in new energy vehicles, not in fuel-powered versions. The EV mode in new energy vehicles refers to the pure electric mode. The vehicle uses the battery to drive the motor, providing power for the vehicle and reducing the use of fuel. Impacts of the fault: When the vehicle indicates a high-voltage system fault, it needs to be driven to the after-sales service at a safe speed. Professional after-sales technicians should inspect the high-voltage system of the vehicle. The vehicle can only be used normally after the high-voltage system fault indicator is cleared. When the vehicle indicates a high-voltage system fault, long-distance driving and high-speed driving are not allowed.
When my friends talk about BYD EV power limitation, it means that BYD's electric vehicles automatically restrict power output under certain circumstances. This usually occurs when the battery management system detects issues such as excessively high battery temperature or critically low charge level, in order to protect vehicle safety by preventing rapid acceleration or high-speed driving. While driving, you may suddenly feel the car losing acceleration power or being unable to reach higher speeds, which happens more frequently during hot summer days or when the battery is undercharged. This is not a minor issue as it involves safety. It's recommended to pull over immediately for inspection or visit a 4S dealership to check specific error codes with diagnostic tools, to prevent potential accidents on the road. Actually, this phenomenon isn't uncommon among electric vehicles. For daily maintenance, pay attention to charging habits—avoid overcharging or prolonged exposure to direct sunlight. I've seen many car owners neglect this, resulting in more severe system failures.
Last year, while driving the BYD Han EV, I experienced an 'EV power limitation' issue where the car suddenly slowed down, which was quite alarming. It means there was a fault in the battery or system, and the car automatically limited power to prevent damage, such as from overheating or low voltage protection. That time, it happened after driving too long on the highway, and the battery got extremely hot, triggering a dashboard warning. Fortunately, I could drive slowly to the service area, and after resting for a while, it returned to normal. I think daily driving requires attention to preheating and charging to avoid putting too much pressure on the battery. If a problem occurs, don’t push it; try turning off and restarting the car or contact after-sales service immediately. Safety comes first. BYD cars are highly reliable, but such minor incidents can still happen occasionally. Regular maintenance can significantly reduce risks. Now, I always check the battery status before long trips.
