Why are electric motors becoming the core of new energy vehicles?

 　　Why electric motors are becoming the core of new energy vehicles? Electric motors are becoming the core of new energy vehicles because of their comprehensive breakthroughs in efficiency, performance, integration and environmental compatibility, which make them an ideal alternative to traditional fuel engines.

　　The energy conversion efficiency of electric motors far exceeds that of fuel engines. Traditional internal combustion engines generate thermal energy by burning fuel, which is then converted into mechanical energy, during which a large amount of energy is dissipated in the form of waste heat, and the actual efficiency is usually less than 40%. On the other hand, electric motors directly convert electrical energy into mechanical energy, and their efficiency is generally over 90%, with some high-performance models even approaching 100%.

　　The performance characteristics of electric motors are perfectly suited to the needs of new energy vehicles. Its torque output can reach its peak value from zero speed without the need to switch gears in a traditional transmission, resulting in smoother acceleration and quicker response. The motor’s speed range is extremely wide and can be infinitely adjusted from low-speed creeping to high-speed cruising through the controller, completely eliminating the reliance on complex gearing mechanisms in fuel vehicles.

　　The bi-directional energy conversion capability of the electric motor gives new energy vehicles a unique ‘regenerative braking’ function. When decelerating or coasting, the electric motor can switch to generator mode, converting the kinetic energy of the wheels into electrical energy and charging it back to the battery, a process that requires no additional energy consumption but extends the range.

　　Why are electric motors becoming the core of new energy vehicles? The structural advantages of electric motors also offer the possibility of lightweight and integrated design for new energy vehicles. Its core components are only the stator, rotor and casing, which are small in size and light in weight, and do not require the auxiliary systems such as air intake, exhaust and cooling required for fuel vehicles, thus significantly saving space inside the vehicle.

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...
