AI Technical Summary

Technical Problem

Existing data center rack power distribution systems or computing servers require the simultaneous configuration of both supercapacitors and BBUs as backup power sources, resulting in high costs, complex management, and low efficiency. Furthermore, the BBU's battery packs require boosting and discharging via a boost circuit, which is highly complex and makes rapid response difficult.

Method used

A hybrid supercapacitor backup power device is adopted, using hybrid supercapacitor cells as energy storage elements. The initial total voltage in the fully charged state is higher than the load equipment requirements. The power supply requirements are met by combining buck discharge and boost discharge. The buck discharge circuit has a simple structure and the control algorithm is easy to implement.

Benefits of technology

It reduces costs, simplifies power management, improves operating efficiency, and enhances the response speed of power control, enabling instantaneous high-power compensation and efficient continuous discharge capabilities.

Abstract

Provided are a hybrid supercapacitor backup power device and a load device. The hybrid supercapacitor backup power device comprises a hybrid supercapacitor battery pack, a control module, a charging module, and a discharging module. The hybrid supercapacitor battery pack uses a hybrid supercapacitor cell as an energy storage element for charging and discharging. The initial total voltage of the hybrid supercapacitor battery pack in a full charge state is configured to be greater than the required voltage of the load device. The charging module is connected to the hybrid supercapacitor battery pack, and the discharging module is connected to the hybrid supercapacitor battery pack. The discharging module comprises a voltage reduction unit for discharging the hybrid supercapacitor battery pack at a reduced voltage and a voltage increase unit for discharging the hybrid supercapacitor battery pack at an increased voltage. The control module is electrically connected to the hybrid supercapacitor battery pack, the charging module, the voltage reduction unit, and the voltage increase unit. The control module can control the hybrid supercapacitor battery pack to first discharge at a reduced voltage and then discharge at an increased voltage through the voltage reduction unit and the voltage increase unit.
