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 engine for long distances, balancing economy and range. The complex structure leads to higher cost and limited pure electric range, which is suitable for users who need to take care of long-distance travelling under stable charging conditions.

　　Extra hybrid vehicles are driven by electric motors as the core, and the fuel engine is only used as a ‘charging treasure’ to generate electricity, which solves the range anxiety of pure electric vehicles. However, under high-speed working conditions, the energy conversion efficiency loss is greater, and the fuel consumption is higher than that of hybrid vehicles, which is more suitable for users who pursue pure electric driving quality and need to travel long distances frequently.

　　Hydrogen fuel cell vehicles generate electricity through the chemical reaction between hydrogen and oxygen, with zero emissions, short hydrogen refuelling time and long range, but the high cost of hydrogen preparation, storage and transportation, and the lack of hydrogen refuelling station infrastructure have limited its promotion, and it is currently more suitable for demonstration operations in specific scenarios.

　　Why don’t all new energy vehicles use the same type of powertrain? Differences in the technical maturity and cost of different powertrains also affect the choice of companies. Although the cost of batteries for pure electric vehicles has been declining year by year, they still account for a high proportion of the overall vehicle cost; hydrogen fuel cell vehicles have high costs because they involve precious metal catalysts and complex systems.
