BMS & PCM


The Battery Management System is a piece of hardware with an electronic system on board that manages a rechargeable battery (cell or pack) and is the link between the battery and it's user. Our BMS includes a control module, a display module, a wireless communication module, and an acquisition module for recording the battery's history.


The acquisition module is connected with the input end of the BMS battery management system; and the output end of the BMS battery management system is connected with the input end of the control module; the control module is respectively connected to the battery pack and the electrical device; and the BMS battery management system is connected to the Server-side through the wireless communication module.Along with the BATTERY MANAGEMENT SYSTEM evolving, more and more functions suitable for this industry will be added gradually.
