Problems solved by technology

In the existing battery test scheme, the power of the commonly tested batteries is relatively small, which is not suitable for the test of high-power battery packs
However, for high-power equipment, it has relatively high requirements on the distribution power of the grid, which has a relatively large impact on the grid, or the test consumes a lot of energy.
Specifically, when testing high-power battery packs (especially for megawatt-level energy storage battery systems), if the existing technology is used, it is necessary for the test site to provide high-power power distribution and high-power cooling equipment. The safety requirements are relatively high, the equipment manufacturing cost is also relatively high, and the accuracy of the corresponding test results is insufficient

Abstract

The embodiment of the invention provides a battery pack test system. The battery pack test system comprises a bidirectional DC / DC converter, an AC / DC power supply module, a controller, an upper computer; a first to-be-tested battery pack and a second to-be-tested battery pack, wherein one end of the bidirectional DC / DC converter is connected with one end of the controller, the other end of the bidirectional DC / DC converter is connected with the first to-be-tested battery pack, and the other end of the controller is connected with the second to-be-tested battery pack and the AC / DC power supplymodule; the upper computer is connected with the controller, the first to-be-tested battery pack, the second to-be-tested battery pack and the AC / DC power supply module; and the controller, the firstto-be-tested battery pack, the second to-be-tested battery pack and the AC / DC power supply module also receive an instruction issued by the upper computer and / or send data to the upper computer. By adopting the system, the accuracy of the performance test of the high-power battery pack can be improved.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a battery pack testing system. Background technique [0002] With the progress of society, green and pollution-free renewable energy has been greatly promoted. Wind power, photovoltaic power generation, new energy vehicles, new energy trains, and high-power battery energy storage are becoming more and more popular. With the rapid development and wider application of batteries (especially lithium batteries), a test application system for battery systems has emerged as the times require. [0003] Facing the increasingly wide application range of batteries, the battery system has developed from a few watts to several megawatts or even tens of megawatts. In the existing battery test scheme, the power of the commonly tested batteries is relatively small, which is not suitable for the test of high-power battery packs. However, for high-power equipment, it has relatively high require...
