Energy recycling control device and control method

Abstract

The invention discloses an energy recycling control device and method, the device comprises a starting power supply, a starting vehicle and an energy absorption device, the energy absorption device comprises a first switch, a second switch, a super capacitor bank, a DC / DC module and a sampling control module, and a power supply output bus of the starting vehicle is connected with the input end of the super capacitor bank; the super capacitor bank is connected with the DC / DC module, and the output end of the DC / DC module is connected with a charging interface of the starting power supply through a power supply input bus; a positive bus of the power input bus is connected to the super capacitor bank through the first switch, a positive bus of the power output bus is connected to the DC / DC module through the second switch, and two ends of the sampling control module are connected between the power input bus and the power output bus. The energy absorption device is used for absorbing voltage peak energy and supplying power to the starting unit or other loads, so that cyclic utilization of energy is realized, the power supply time or starting times of the starting power supply is increased, and the circuit is simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an energy recovery control device and control method. Background technique [0002] The increase in the types of vehicle products and the aggravation of resource shortages make the application of new energy products more extensive. At present, there will be a certain voltage peak when the on-board generator is turned on or off. For example, a certain voltage peak will appear when a 12V / 24V vehicle is started. The energy of this peak depends on the power of the motor. Energy recovery can reduce the impact of the peak The impact of the equipment on the vehicle bus can improve the service life of the product. [0003] In the related technology, the invention patent application with the application number 202011024227.1 discloses a voltage spike noise lossless absorption circuit, including diodes D1, D2, D3, capacitors C1, C2, C3 and inductor L1, diode D1, inductor L1 and dio...

Problems solved by technology

[0004] However, the peaks that appear on the vehicle bus are absorbed by capacitors or discharged by resistors. The energy is not recycled, and the waste is serious. The cruising range of the product has not been significantly improved.
