Although electric vehicles have obvious advantages in environmental protection, there are still some inevitable problems in their development.
First of all, battery technology is still not able to achieve instantaneous full charge, so the battery replacement mode is required. However, the cost of this model is not advantageous, so it cannot be applied at scale.
Secondly, the scarcity of charging places cannot be solved. The construction of charging stations needs to occupy a lot of land resources, and with the scarcity of land and the increase of cost, charging costs will inevitably rise. In addition, the breakthrough of energy storage technology does not yet see a clear light, and even if it does, battery prices will still be prohibitive.
In addition, electric vehicles have high energy consumption in heating, and the higher the speed, the lower the motor efficiency, which is also the bottleneck of its development. Fuel vehicles, on the other hand, have advantages because they do not need to burn oil for heating, and 80-100 is the economic range of the engine.
Finally, as long as the sale of fuel vehicles is not mandatory and does not discriminate, fuel vehicles will still have market demand.
Therefore, although electric vehicles have advantages in environmental protection, there are still many problems in technology, economy and other aspects, and they cannot completely replace fuel vehicles.
