Past generations of electric vehicles used the DC motor/controller system because they operate off the battery current without complex electronics. The DC motor/controller system is still used today on some electric vehicles to keep the cost down.
Drive motor design and motor control technologies As the energy conversion and power transmission system of EVs, drive motors and their controllers are an important part of the “Three Verticals and Three Horizontals” R & D layout for China's new energy vehicles, with the trendency of higher efficiency, higher power density, and higher reliability.
With this type of system, a large percentage of the energy from the battery was wasted as an energy loss in the resistor. The only time that all of the available power was used was at high speeds. Modern controllers adjust speed and acceleration by an electronic process called pulse width modulation.
The EV power battery system consists of hundreds or thousands of cells. The battery packing theory and structural integration, management systems and methods, and safety management and control technologies for power batteries are the keys to the application of EVs. 3.2.1. Power battery packing theory and structural integration
The power system of an electric vehicle consists of just two components: the motor that provides the power and the controller that controls the application of this power.
To systematically solve the key problems of battery electric vehicles (BEVs) such as “driving range anxiety, long battery charging time, and driving safety hazards”, China took the lead in putting forward a “system engineering-based technology system architecture for BEVs” and clarifying its connotation.
