The embodiment of the invention discloses direct current electric quantity calculation equipment and method, and the direct current electric quantity calculation equipment which is formed by integrating a voltage detection unit, a data processing unit, a high-voltage isolation unit and a power supply processing unit into a whole is electrically connected to a high-voltage storage battery pack. The data processing unit is used for processing a weak voltage signal generated by the voltage detection unit into a target digital signal, current integration is adopted for completing target electric quantity calculation of the high-voltage storage battery pack, and then the target electric quantity is sent to the main control unit of the storage battery pack management system of the high-voltage storage battery pack. The functions of high-speed and high-precision current acquisition and electric quantity calculation are realized, so that the main control unit of the storage battery pack management system can master the electric quantity state of the high-voltage storage battery pack in time; and the high-voltage isolation unit isolates the high-voltage side from the low-voltage safety side, and the withstand voltage value can reach AC5000Vrms, so that the equipment safety and personnel safety are further ensured, and the direct-current electric quantity calculation equipment which is low in cost, high in stability and easy to use can be provided.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a DC power calculation device and method. Background technique [0002] A battery is an energy storage device that can convert chemical energy into electrical energy. With the development of new battery technology, batteries have been used in various industries. At present, shield machines are used in the construction of subway tunnels in my country. The muck generated during the excavation process is transported to the wellhead by the electric locomotive that is transported horizontally in the tunnel, and the construction materials such as segments and mortar are transported from the wellhead to the tunnel by the electric locomotive that is transported horizontally in the tunnel. internal. The battery system provides electric energy for the electric locomotives for horizontal transport in the tunnel, and drives the electric locomotives for horizontal transport in the tunnel. ...
