What are the common faults of ordinary electric classic cars?

Electric classic cars are environmentally friendly buses specially developed for real estate communities, tourist attractions, parks, large amusement parks, closed communities, campuses, garden-style hotels, resorts, villas, urban pedestrian streets, airports, ports and docks. It has excellent performance, luxurious appearance and nostalgia for Jin Dian. The appearance is novel and the interior is luxurious and exquisite. Comfortable and safe, it is an ideal electric sightseeing bus. But we will have some faults when using electric classic cars, so what are the causes of the faults? As follows: 1. Fault symptoms: the ammeter pointer is reset too fast during driving after starting, or the battery temperature of the electric classic car is too high, and the ammeter pointer still points to more than +5A after driving for a long time. 2. Cause of failure: (1) battery strain of electric classic car. (2) There is an internal short circuit fault. (3) The active substance on the electrode plate falls off, resulting in too small capacity. (4) Vulcanization of polar plate or hardening of negative plate. 3. Fault diagnosis and elimination: For the fault diagnosis of electric classic car battery, it is necessary to comprehensively analyze the fault phenomenon and its use to make a judgment. If the battery of an electric classic car is used for more than one year, the above phenomenon occurs. Generally speaking, the battery of an electric classic car has been exhausted and should be replaced with a new one. If the battery temperature of an electric classic car is on the high side, the ammeter pointer still points above +5A after driving for a long time, which can be detected by a high-rate discharge meter. If the measured voltage of a battery is lower than 1.5V, it means that the battery has a short circuit fault and should be disassembled for maintenance. Why is the continuous charging mileage insufficient? Possible causes of failure: 1, insufficient battery power before use, insufficient tire pressure, aging or damage of battery, strong wind slope, frequent braking, heavy load, 5, inability to charge or insufficient charging. Troubleshooting methods: 1, sufficient power before use, 2, sufficient air before use, 3, battery replacement, 4, low speed driving, brake reduction.
