Embodiment
[0028] This embodiment combines the attached Figure 1-5 Implemented in: in figure 1 Among them, including battery 1, drive controller 2, motor 3, supercapacitor charging and discharging controller 4, supercapacitor module 5 and cable busbar 6, each component is connected with each other according to the principle of electricity to form an energy storage device; figure 2 Among them, Cn is a supercapacitor module, SA1~SA6 are current sensors, SV1~SV2 are voltage sensors, and Rn is a discharge resistor. Through multiple structures, the defect of large current ripple is overcome, and high power density and good dynamic response are obtained. features. When the supercapacitor module is fully charged, Rn is used as a absorbing resistor, and when the supercapacitor module needs maintenance, Rn is used as a release resistor; image 3 Among them, when the drive controller is working, the output voltage of the supercapacitor module is stabilized within the load range through the vol...
