The invention discloses a mechanical in-parallel modularized combined type electric driving system with batteries serving as energy sources. The mechanical in-parallel modularized combined type electric driving system comprises one or more electric driving units and one or more controllers. The electric driving units are connected with the controllers through buses, and output ends of the electric driving units are in rigid connection through mechanical structures. Each of the electric driving units comprises a battery, a battery detection circuit, a power regulator, an external power supply, an electromotor and a power transmission mechanism, wherein the battery detection circuit detects work statuses of the battery and transmits a detection signal to the power regulator connected with the battery, the external power supply and the electromotor, and the electromotor performs power output through the power transmission mechanism. According to the mechanical in-parallel modularized combined type electric driving system, energy of the batteries can be supplemented easily, requirements on design of a battery management system are lowered down, each of the electric driving units does not need too many batteries, complexity of the battery management system is greatly reduced, and reliability and stability of the system can be improved. Therefore, the mechanical in-parallel modularized combined type electric driving system is flexible to use and convenient to maintain.
Description
technical field [0001] The invention relates to an electric drive system, in particular to a mechanical parallel modularized combined electric drive system using batteries as energy sources. Background technique [0002] With the rising price of traditional petroleum energy and the environmental pollution caused by its extensive use, people have to think about its alternative solutions. The battery-powered electric drive system has gained widespread attention due to its good economy and environmental friendliness. Over the years, it has also achieved some extensive applications, especially in the range of low speed and low power (such as electric bicycles). However, due to some technical problems, the application of electric drive systems powered by batteries in relatively high-power applications is relatively limited. [0003] The main reason is that there are the following technical problems: less power means that the requirements for use can be met with less current and...
