Problems solved by technology

[0002] In order to cope with the energy crisis, new energy technologies represented by wind energy and solar energy have developed rapidly, but wind energy and solar power generation have problems such as intermittency, volatility, and instability.
These problems also bring challenges to the charging of the battery. Fluctuating and unstable charging will reduce the life of the battery
In addition, in weak wind and rainy days, the weak electricity generated by wind energy and solar energy cannot be stored in the battery with large internal resistance, resulting in a waste of energy

Embodiment

[0042] Such as figure 1 As shown, a stable peak power supply system includes an energy type capacitor, a power type capacitor and a control system; the control system is provided with three positive and negative interfaces, which are respectively an energy type capacitor interface, a power type capacitor interface and an input and output interface; The energy-type capacitor in the embodiment has a relatively high energy capacity of 60-400Wh, a minimum charging current of 0.2A, and a maximum charging current of 20A. In this embodiment, the power type capacitor can withstand the impact of relatively large charge and discharge current, the maximum charge current is 50A, has a small internal resistance, and can absorb weak current.

[0043] In this embodiment, the control system is composed of a DC / DC unit, an acquisition unit and a control unit.

[0044] Such as figure 2As shown, the DC / DC unit in this embodiment is mainly composed of 5 MOS transistors and 1 inductor to form a...

Abstract

The invention discloses a stable-peak power supply system and an operation method thereof. The system comprises an energy type capacitor, a power type capacitor and a control system. The control system comprises a DC / DC unit, an acquisition unit and a control unit. Three positive-negative ports are arranged in the control system and include an energy type port, a power type port and a control port. According to the invention, by monitoring voltage and input-output current of a super-capacitor, and controlling turning on and turning off actions of the DC / DC unit, peaking clipping and valley filling of the input-output current of the energy type capacitor by the power type capacitor are achieved; the energy type capacitor is protected against impact of big current; service lifetime is extended; the ability of instantaneously releasing and absorbing electric quantity of the energy type capacitor is enhanced; during weak-current charging, the control system connects charging to the power type capacitor with quite small inner resistance through the change-over switch, thereby facilitating absorption of weak electricity.

Description

technical field [0001] The invention relates to a power management system, in particular to the design of a hybrid power supply of an energy type capacitor and a power type capacitor. Background technique [0002] In response to the energy crisis, new energy technologies represented by wind energy and solar energy have developed rapidly, but wind energy and solar power generation have problems such as intermittency, volatility, and instability. These issues also present challenges to battery charging, as fluctuating and erratic charging can reduce battery life. In addition, in weak wind and rainy days, the weak electricity generated by wind energy and solar energy cannot be stored in the battery with large internal resistance, resulting in a waste of energy. [0003] In order to cope with environmental pollution and poor air quality, the country vigorously promotes new energy vehicles, and electric vehicles enter the market, and the power supply system is the key technology...
