技术领域Technical Field
本发明涉及供电系统技术领域，尤其涉及一种不间断供电智能切换及监控方法。The present invention relates to the technical field of power supply systems, and in particular to an uninterruptible power supply intelligent switching and monitoring method.
背景技术Background technique
在储能系统中，电池管理系统BMS起到至关重要的作用，它可以保护电池堆使其工作在适当的范围以内，防止电池堆出现过度充电以及过度放电的情况。In the energy storage system, the battery management system BMS plays a vital role. It can protect the battery stack so that it works within the appropriate range and prevent the battery stack from overcharging and over-discharging.
在储能系统的使用过程中，可能会出现市电断开的情况，此时，需要继续为电池管理系统BMS及其部件供电，致使电池管理系统BMS及其部件继续工作。During the use of the energy storage system, the mains power may be disconnected. At this time, it is necessary to continue to supply power to the battery management system BMS and its components so that the battery management system BMS and its components continue to work.
为了给电池管理系统BMS及其部件提供一个稳定电源，现有的储能系统中，在市电断开时，利用铅酸电池为电池管理系统BMS及其部件供电。但是，铅酸电池的能量密度较低，因此，不间断电源模块的占用空间大。进一步地，铅酸电池至少每隔半年需要进行一次维护，且使用寿命短，因此，在市电断开时，可能铅酸电池已经出现故障，从而不能为电池管理系统BMS及其部件供电，进而仍存在供电不稳定的问题，进一步地，工作人员也不能即时获知铅酸电池的异常情况。In order to provide a stable power supply for the battery management system BMS and its components, in the existing energy storage system, when the mains is disconnected, lead-acid batteries are used to power the battery management system BMS and its components. However, the energy density of lead-acid batteries is low, so the uninterruptible power supply module occupies a large space. Furthermore, lead-acid batteries need to be maintained at least once every six months and have a short service life. Therefore, when the mains is disconnected, the lead-acid battery may have failed and cannot power the battery management system BMS and its components, and the problem of unstable power supply still exists. Furthermore, the staff cannot immediately know the abnormal situation of the lead-acid battery.
