What are the differences between UPS batteries and EPS batteries?

What are the differences between UPS batteries and EPS batteries? 1. Different meanings UPS means uninterruptible power supply. It is a system equipment that connects batteries (mostly lead-acid maintenance-free batteries) to the host and converts DC power into mains power through the host inverter and other module circuits. EPS stands for emergency power supply. It is an emergency power supply used for emergency lighting, accident lighting, and fire-fighting facilities in important buildings today. 2. Different components UPS battery system consists of five parts: main circuit, bypass, battery and other power input circuits, rectifier (REC) for AC/DC conversion, inverter (INV) for DC/AC conversion, reverse Transformation and bypass output switching circuit and energy storage battery. The EPS battery is mainly composed of input unit, output unit, charging module, battery pack, inverter, monitor, output switching device, etc. The system can supply emergency power supply in an emergency state. 3. Switching time Different UPS battery power supply modes require a very short switching time (0～10ms), while EPS emergency power supply is relatively wide (0～4s). 4. EPS power supply battery inverters with different structures have large redundancy. Both the incoming and outgoing cabinets are inside the EPS, and the motor load is started with variable frequency. The casing and wires have flame-retardant measures, and have multi-channel mutual input power, which can be linked with fire protection. The inverter redundancy of the UPS power supply battery is relatively small, has nothing to do with fire protection, does not need to be flame-retardant, and has no mutual input function. The UPS power load is a capacitive load, and the main band equipment is generally a computer, which is mainly used in a large computer room to ensure uninterrupted power supply and voltage stabilization.
