Description

technical field [0001] The invention relates to the technical field related to electric bicycles, in particular to a device and method for an electric bicycle sliding and braking energy recovery system. Background technique [0002] Electric bicycles, that is, electric-driven bicycles, electric bicycles use batteries as energy sources, through controllers, motors and other components, convert electrical energy into mechanical energy movement, to control the current and change the speed of the vehicle. Electric bicycles often brake during driving. If the number of brakes is too high, electric energy will be wasted. Therefore, it will have a negative impact on the battery life of electric bicycles. Compensation devices have been widely used. [0003] Patent No. CN201210369168.0 discloses a vehicle brake energy recovery device, including a base, an energy recovery mechanism, a power generation mechanism, a locking mechanism and a control system. The energy recovery mechanism i...

Problems solved by technology

[0004] However, the above-mentioned vehicle energy recovery device has the following technical defects in use: because it adopts the internal gear on the energy recovery block to drive the central gear to rotate at a high speed through the planetary gear to drive the generator to generate electricity to realize energy recovery when the vehicle brakes, that is, the vehicle The energy recovery device uses the central gear to drive the generator to rotate during the energy recovery, and the energy recovery is completed under the braking state. For the electric bicycle, its operating state includes not only acceleration and braking, but also coasting. state, and there is a certain difference in the energy recovery of the electric bicycle when it is coasting or braking, that is, when the electric bicycle is in the coasting state, its power generation structure should control the resistance to the wheels during power generation within a small range to ensure The normal sliding of the wheels; when the electric bicycle is in the braking state, its power generation structure should be able to exert a certain resistance effect on the running of the wheels when generating electricity, so as to be able to play the effect of auxiliary braking. Therefore, the present invention proposes a Device for electric bicycle coasting and braking energy recovery system for judging energy recovery mode
