What are the reasons why the Roewe ei5 pure electric vehicle cannot start?
2 Answers
It may be due to insufficient battery power. When an electric vehicle cannot start, the first thing to check is whether the power supply is adequate: a simple method is to use the anti-theft device to lock and unlock, which proves that the battery has power. If not, plug in the car key to see if the dashboard displays the battery level. Signs of a failing car battery are as follows: Difficulty starting the car: If the car suddenly has trouble starting without other factors, it may be a sign that the battery is about to fail. Dimming lights during idle: For example, when waiting at a red light or temporarily parked, the headlights suddenly dim. This is because the charging power of the engine decreases during idle. Battery fault light comes on: When the battery fault light comes on, it reminds the owner to go to a repair shop for battery maintenance and testing. Normally, the car runs smoothly, but occasionally after parking, it is found that the whole car has no power when starting again: This is because when the battery life is nearing its end, the starting current is insufficient, causing an increase in oxide on the battery terminals, resulting in a no-power problem for the entire car.
I've been driving the Roewe ei5 for two years, and I've also encountered the issue of not being able to start the car. The main problem was a dead 12V auxiliary battery. Besides the main battery, pure electric vehicles have a 12V small battery responsible for the starting system. If you forget to turn off the headlights or leave the car unused for too long, this battery can easily drain. A critically low high-voltage battery can also prevent startup, as the system automatically locks when the charge drops below the protection threshold. Charging issues should also be checked, especially poor contact in the slow charging port, which can cause the vehicle to mistakenly think it's charging. Another pitfall is a dead key fob battery—new car keys typically last about two years. System errors can also occur; for example, last time my infotainment system froze, and a reboot fixed it. It's recommended to first check the voltage of the small battery—if it's below 12V, you'll need a jump start. Then, visiting a service center to read the fault codes is the safer option.
