What are the reasons why the Roewe ei5 pure electric vehicle cannot start?

When an electric vehicle fails to start, first check if the power supply is sufficient: a simple method is to use the anti-theft device to lock and unlock, proving that the battery is in a charged state. If not, insert the car key to see if the meter displays any power. Signs of a failing car battery are as follows: 1. Difficulty starting the car: Under normal circumstances, if the car suddenly becomes difficult to start, it may be a sign that the battery is about to fail. 2. Dimming lights when the car is idling: For example, when waiting at a red light or temporarily parked, the headlights suddenly dim. This is because the engine's charging power decreases when idling. 3. Battery fault light turns on: When the battery fault light comes on, it reminds the owner to go to a repair shop for battery maintenance and testing. 4. The car runs normally during regular driving, but occasionally after parking and restarting, the entire vehicle has no power: This is because when the battery's lifespan is nearing its end, the starting current is insufficient, causing an increase in oxide deposits on the battery terminals, resulting in a total loss of power in the vehicle.
If your Roewe ei5 electric vehicle won't start, don't panic—it's most likely due to a dead auxiliary battery. EVs have a 12V auxiliary battery responsible for the starting system, which can prevent ignition when aged or depleted, much like a phone that won't turn on without power. First, check if the dashboard shows a battery warning light or try the emergency start function. Keeping a portable jump starter at home can be very helpful. Regularly inspect the auxiliary battery's lifespan and replace it every two years. Charging stations may also refuse to operate if the voltage is too low, so ensure the car is properly charged before trying again. If these steps don’t work, the issue might lie with the high-voltage battery, such as a controller malfunction or software bug. In such cases, it's best to take the car to a 4S dealership for diagnosis—they can plug in a computer to read specific error codes and prevent further damage.
