Embodiment Construction

[0026] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0027] In order to facilitate the understanding of the technical solution of the present invention, a traditional electric-electric hybrid charging and discharging system is introduced first. Such as figure 1 As shown, the traditional electric-electric hybrid charging and discharging system includes a motor, a motor control system, a battery pack, a capacitor module, and a coupling controller. Among them, the motor is composed of a group of three-phase inductance coils, which is not substantially different from the motor of traditional technology. When the motor accelerates, it acts as a load to consume electric energy; when the motor decelerates or stops suddenly, it acts as a generator to generate electric energy; the motor control system is mainly composed of a rectifier bridge composed of IGBT as a switching device and an IGBT driv...

Abstract

The invention discloses an electric-electric hybrid energy recycling device and method. The electric-electric hybrid energy recycling device comprises a battery pack, a motor, a motor control system and a capacitor module, wherein the battery pack and the motor are both connected with the motor control system through buses; the device further comprises a collecting system, a control unit, a direct current converter, a rectifier module and the capacitor module; the collecting system is mounted on a connecting line between the motor control system and the battery pack; the control unit is connected with the collecting system, the rectifier module, the direct current converter and the capacitor module; the rectifier module is connected with the capacitor module; the capacitor module is connected with the direct current converter and the control unit; and the direct current converter is connected with the battery pack. According to the invention, instantaneous large-current borne on the battery pack is avoided so that the battery pack is prevented from suffering the impact of the instantaneous large-current generated by the motor. Meanwhile, the time of endurance of the battery pack is prolonged. The cost of the electric-electric hybrid energy recycling device is reduced and the size of the electric-electric hybrid energy recycling device is reduced.

Description

technical field [0001] The invention belongs to the field of drive technology, and in particular relates to an energy recovery device and method for a capacitor and battery hybrid system (referred to as electric-electric hybrid). Specifically, when loads with power generation functions such as motors are in the power generation state, the output AC power can be converted to charge the capacitor and store energy. The invention is suitable for electric and electric hybrid motor drive circuits. Background technique [0002] In an energy-saving system composed of batteries and capacitors, when the motor acts as a load to increase power, the battery pack and capacitor pack are in a discharge state to meet the current needs of the load when the load is high-power, and when the load needs to consume a large amount of current in a short time At this time, the capacitor bank is often used to supplement energy to avoid over-discharge of the battery in a short period of time, thereby ...
