Which new energy vehicle parts are most prone to failure?

　　Which new energy vehicle accessories are most prone to failure? New energy vehicles are significantly different in structure and technology compared to traditional fuel vehicles, which leads to the uniqueness of their accessory failure modes.

　　Although modern battery technology has come a long way, batteries still face multiple challenges such as temperature variations and the number of charge/discharge cycles. Prolonged exposure to extreme temperatures or frequent rapid charging can accelerate the aging process, affecting performance and even causing capacity to drop too quickly.

　　The electric motor is responsible for converting electrical energy into mechanical energy to drive the vehicle, which directly affects the overall performance of the vehicle. The complex electronic components inside the motor and the heat generated by long periods of high-load operation can be a trigger for failure. If a component in the motor controller is damaged, the motor may not start properly or may produce abnormal noise during operation.

　　In order to ensure sufficient power transmission, new energy vehicles are usually designed with high-voltage circuits, which place high demands on the quality of the cables and the sealing of the joints. Any small breakage or poor contact can lead to increased resistance, which in turn can cause localised overheating and, in severe cases, fire.

　　The on-board charging unit is also a potential problem area. During long-term use, the electronic components inside the charger may become damaged due to overloading or other reasons, which can affect the normal charging process. This is especially true when switching between different voltage standards, which is more likely to cause damage if proper protection is not in place.

　　Which new energy vehicle parts are most prone to failure? Although the design of the components of new energy vehicles is moving towards greater reliability, the aspects mentioned above are still the ones that need to be focussed on. Maintenance personnel and vehicle owners alike should remain vigilant in preventing potential problems through regular inspections and maintenance.

Why don’t all new energy vehicles use the same type of powertrain?

 　　Why don’t all new energy vehicles use the same type of powertrain? The core reason why new energy vehicles do not uniformly adopt a single powertrain is that there are significant differences between different technology routes in terms of performance, applicable scenarios and infrastructure requirements, and companies need to choose the optimal solution based on technical characteristics and market demand. 　　Pure electric vehicles use batteries as the only power source, with a simple structure and outstanding zero-emission advantages, but range and charging time are still bottlenecks. However, performance degradation in low-temperature environments and insufficient coverage of charging facilities still limit their application in long-distance travelling or inconvenient charging areas. 　　Plug-in hybrid vehicles combine a fuel engine with an electric motor to achieve pure electric driving for short distances through external charging, while relying on the fuel engin...

Where does the power for new energy vehicles come from?

 　　Where does the power for new energy vehicles come from? The power sources for new energy vehicles are diverse, primarily including electricity and hydrogen fuel. These energy forms are more environmentally friendly and sustainable compared to the petroleum used in traditional fuel-powered vehicles. 　　Electricity is the primary power source for new energy vehicles. Pure electric vehicles rely entirely on batteries and electric motors for propulsion, without an internal combustion engine. Batteries are charged at charging stations or using home chargers, and electric motors convert electrical energy into power to drive the vehicle. 　　Hydrogen fuel is another important power source for new energy vehicles. Fuel cell vehicles use hydrogen as fuel, combining hydrogen and oxygen through fuel cells to generate electricity. This process only produces water vapour and other harmless by-products. The batteries in fuel cell vehicles utilise this electricity to drive the vehic...
