1. High energy conversion efficiency

The electric motor is the execution component of the external work of the electric drive system. Its energy conversion efficiency can generally reach 75% to 90%. It is much more efficient than the heat engine. The Sterling engine is the current advanced high-efficiency heat engine, and its efficiency is only about 30%. The general heat engine has a lower energy conversion rate, so when driving in urban areas, the energy efficiency of electric vehicles is about 40% higher than that of ordinary gasoline engine vehicles..., so hybrid electric vehicles are currently the darling of countries around the world scrambling to develop.

2. No pollution, zero emissions, and friendly to the environment

The development of the automobile industry has greatly polluted the living environment of mankind, especially in large cities. The exhaust gases emitted by various motor vehicles have seriously harmed human health. In developed industrial countries, this hazard is particularly serious.As a result of the work of the electric drive system, no substances will be discharged, that is, zero emissions and environmentally friendly.Therefore, gradually replacing gasoline vehicles with electric vehicles is the direction of efforts of countries around the world today.

3. Flexible and convenient control of working status

As long as the driver gives an electrical signal command, the output power of the system and the working state of the control system can be changed immediately, regardless of the distance limit, and there is no intermediate transmission device, that is, the responsiveness of the electric drive system is very good.

4. The working state of the system will not be affected by the external environment

When using a heat engine as a power source, there must be an oxidant (or air) to ensure the normal operation of the system. Therefore, a heat engine cannot be used as an underwater propulsion power source. For example, a submarine must be powered by a battery for underwater navigation.

5. The overall weight remains the same

No waste is discharged during the work of the electric drive system, so its total weight is unchanged.This feature is very important for submarines and torpedoes working underwater, and it will not affect the overall ups and downs of submarines and torpedoes.

6. No noise and no impact on the environment

Since there is no mechanical transmission device, the electric drive system will not produce noise during the work process, which is particularly suitable for electric vehicles in cities and some special-purpose equipment.

7. Good safety

Whether on land or underwater, the safety of propulsion power systems is a key factor in whether they can be adopted.Although the energy density of some batteries is very high, they are finally forced to be eliminated due to substandard safety.
