The future trend of new energy vehicles
In the future, under the crisis of global oil reserves, greenhouse effect and environmental pollution, it is clear and irreversible to switch from internal combustion engine to drive motor for vehicle power.
Due to the impact of the epidemic, global vehicle sales in 2020 were less than 70 million units, but electric vehicle sales increased instead of decreasing, with 2.5 million units sold.
Electric vehicles are expected to continue to grow at a significant compound annual growth rate in the future.The indispensable drive motor in the new energy vehicle system.
