Drive innovation with user needs and technological R & D to promote industry progress
The DC supercharged liquid-cooled feedback load is a special equipment for testing and aging of emerging super charging pile products. This series of products integrates the BMS vehicle interface and is equipped with a liquid cooling system. The maximum current of a single channel can reach 1000A. Multi-channel design, the number of channels and power distribution plan can be customized according to the actual requirements of customers. This series adopts proprietary active inversion technology, which can not only meet the requirements of test power experiment, but also can invert the electric energy generated by the power supply and return it to the grid, so that the electric energy can be recycled. At the same time, it can also be used as a special equipment for DC charging pile aging test. It integrates two functional modules of DC charging pile simulation and energy-saving feedback load. It can be directly used for DC charging pile aging and functional testing without adding a simulation device, which greatly simplifies the process flow. This product can be widely used in new energy, electric power, photovoltaic, communication-related companies, scientific research institutes and testing institutions, effectively helping companies to intelligently manage production lines, greatly reducing electrical energy costs in the testing process, reducing production costs, and increasing aging capacity.
