Product Description
1MWh Container energy storage system battery energy storage 1mwh
The Battery Management System (BMS) is mainly composed of a main control module, a GPRS remote monitoring module, a display module and multiple acquisition modules and accessories (harness, Hall sensor, DC relay, etc.). The OPT battery management system is an important system component of the energy storage system. The main task is to monitor the status of the cell voltage, temperature, total voltage and total current of the lithium-ion battery. The battery management system performs data communication with the energy storage converter and executes the corresponding Control strategy, predicting the charge capacity of the lithium-ion battery (referred to as SOC), completing the charge and discharge detection, communicating with the energy storage converter and controlling the charge and discharge status; thermal management, storing operating data such as battery cell voltage, fault alarms and The relay control records, diagnoses and alarms battery faults, and transmits data to the data center through GPRS, reminding after-sales personnel to deal with it in a timely manner, and ultimately prevents the battery from overcharging and over-discharging, ensuring battery safety and other functions. Each component module uses CAN communication for information exchange and control management. Each acquisition module can collect up to 12 strings of battery voltage. The number of acquisition modules can be configured according to the battery structure. The acquisition module collects the collected unit voltage, temperature, current, etc. The information is uploaded to the host module for processing and display. The display module can display BMS status information and parameter configuration. The host module communicates with the energy storage converter and the main control center through the CAN bus to report the operating status of the battery pack. The main control center Perform corresponding charging and discharging decisions through battery configuration information.
