Enterprise energy management: How energy storage devices work

Battery management system (BMS) plays a vital role in new energy storage equipment. BMS is like the "brain" of the energy storage battery, responsible for real-time monitoring and management of the battery status. It can accurately measure the battery's voltage, current, temperature and other parameters to ensure that the battery operates within a safe range. When the battery is overcharged, over-discharged, overheated, and other abnormal conditions occur, BMS will take protective measures in time to prevent battery damage and extend the battery's service life. At the same time, BMS can also accurately estimate the remaining capacity of the battery, providing an important basis for the operation and scheduling of commercial energy storage systems.

The operating mechanism of new energy storage equipment mainly includes the following key links. The first is the charging link. When there is excess electrical energy available for storage, such as excess new energy generation or low power consumption in the power grid, the energy storage device will store the electrical energy in the energy storage battery through a specific charging circuit. In this process, BMS will closely monitor the charging status to ensure that the charging process is safe and efficient. The second is the storage link. The energy storage battery stores electrical energy in the form of chemical energy and waits for the right time to release it. During storage, BMS continuously monitors the battery status to prevent battery performance degradation or safety problems. Finally, there is the discharge link. When the enterprise needs electricity or the power grid is at a peak period of electricity consumption, the energy storage device will release the stored electricity according to the instructions. During the discharge process, the BMS will also strictly monitor the discharge status to ensure the stability and safety of the discharge.

For enterprises, new energy storage equipment brings many benefits. On the one hand, it can improve the stability and reliability of the enterprise's energy supply and reduce dependence on traditional power grids. Especially in the case of power grid failure or instability, energy storage equipment can be used as a backup power supply to ensure the normal production and operation of the enterprise. On the other hand, by rationally using energy storage equipment to participate in the peak-shaving and valley-filling of the power grid, enterprises can reduce electricity costs and improve energy utilization efficiency. In addition, new energy storage equipment is also in line with the concept of sustainable development, which helps enterprises reduce carbon emissions and achieve green development.
