Problems solved by technology

In the prior art, the energy storage device is mainly discharged through a constant resistance and an adjustable resistance. In the process of discharging with a constant resistance, because the resistance is a constant value, the discharge current will gradually decrease during the discharge process. Small, so the discharge power will gradually decrease, so it takes a long time to discharge the power in the energy storage device, and the efficiency is relatively low

Abstract

The invention discloses a discharge device. The discharge device comprises a first current transforming module, a second current transforming module, a power supply module, a blower module and a discharge module; the output end of the energy storage device is connected with the input end of the first current transforming module and the input end of the second current transforming module separately, the output end of the first current transforming module is connected with the discharge module, and the output end of the second current transforming module is connected with the input end of the power supply module and the input end of the blower module separately; the first current transforming module outputs first voltage, the second current transforming module outputs second voltage, and thefirst voltage is greater than the second voltage. In this way, the first current transforming module can enable the discharge module to discharge in a constant state, the power supply module and theblower module in the second current transforming module also consume a certain amount of energy, and meanwhile, the blower module also has a heat dissipation function, so that the discharge device hasthe advantages of being high in discharge efficiency, simple in structure and convenient for staff to use. Correspondingly, the invention further discloses a discharge system of the energy storage device. The discharge system of the energy storage device also has the advantages above.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a discharge device and an energy storage device discharge system. Background technique [0002] With the development of social economy, energy storage devices, as a new type of green energy, have attracted more and more attention from people, and the main function of the discharge device of energy storage devices is to release the electricity stored on the energy storage devices in the form of heat. Lose. In the prior art, the energy storage device is mainly discharged through a constant resistance and an adjustable resistance. In the process of discharging with a constant resistance, because the resistance is a constant value, the discharge current will gradually decrease during the discharge process. Small, so the discharge power will gradually decrease, so it takes a long time to discharge the electricity in the energy storage device, and the efficiency is relativel...
