Jidu Electric Car are now very common, as many elderly people find driving difficult, leading to their increasing use. However, some common malfunctions can occur during use. Let's take a look:
1. Excessive noise is a frequent problem, mainly caused by: ① Large clearance in the motor's bearings. ② Motor rotor rubbing against the stator. ③ Loose or detached magnets. ④ Axial movement within the motor. ⑤ Oxidation, burning, oil stains, unevenness, or loose commutator segments on the commutator surface of brushed motors.
2. A common Electric Car malfunction is a dashboard that doesn't display anything. This is mainly caused by no voltage between the positive and negative leads of the dashboard, a short circuit in the wires or connectors, or damage to the dashboard itself.
3. If the wheels start spinning immediately upon powering on, and the speed increases rapidly, this is called "runaway" or "runaway" malfunction. This is often caused by a poor grounding connection on the throttle, or it could be a controller malfunction.
4. Speaker malfunction is often caused by damage to the speaker, a faulty switch, or a short circuit in the connecting wires or connectors. These are the main areas to check during troubleshooting.
