Discharge current of portable energy storage power supply

Which energy storage battery is used in pulsed power system?

In this paper, according to the energy and weight requirements of the pulsed power system, the ANR26650M1B lithium iron phosphate (LFP) power battery produced by A123 Company of the United States was selected as the energy storage battery, and the capacity of a single battery as well as the discharge characteristics of the test.

What are high-power energy storage devices?

For this application, high-power energy storage devices with sophisticated power electronics interfaces—such as SMES, supercapacitors, flywheels, and high-power batteries—have become competitive options. These storage devices can sense disturbances, react at full power in 20 ms, and inject or absorb oscillatory power for a maximum of 20 cycles.

What is a pulsed power supply?

As industrial applications place higher requirements on compact and portable pulsed power supplies, the National Key Laboratory of Transient Physics (NKLTP) recently developed a pulsed power supply consisting of a set of compact pulse-forming units (PFU), each with a capacitor energy storage of 220 kJ.

How does a power supply work?

The power supply is powered by a 32 V lithium battery pack with high energy storage density, boosted to about 400 V through the intermediate stage of a non-isolated DC-DC boost converter, and then connected to an isolated phase-shifted full-bridge DC-DC converter, outputting a high voltage of 50 kV.
