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

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0035] The embodiment of the invention discloses a discharge device, such as figure 1 As shown, the discharge device includes:
[0036] The first converter module 101, the second converter module 102, the power module 103, the fan module 104 and the discharge module 105;
[0037] The output terminal of the energy storage device is connected to the input terminal of the first converter module 101 and the input terminal of the second converter module 102 respec...

The present application discloses a discharge device, including: a first converter module, a second converter module, a power supply module, a fan module and a discharge module; the output end of the energy storage device is connected to the input end of the first converter module and the The input terminals of the second converter module are connected, the output terminal of the first converter module is connected with the discharge module, and the output terminal of the second converter module is respectively connected with the input terminal of the power module and the input terminal of the fan module; wherein, the first converter module The current module outputs a first voltage, the second converter module outputs a second voltage, and the first voltage is greater than the second voltage. It can be seen that the first converter module can enable the discharge module to discharge constantly, and the power module and fan module in the second converter module also consume a certain amount of electric energy. At the same time, the fan module also plays a role in heat dissipation. The discharge efficiency of the device is high, the structure is simple, and the staff is convenient to use. Correspondingly, an energy storage device discharge system disclosed in the present invention also has the above beneficial effects.
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...
