Lithium-ion battery terms explained

Aug , 18 2023

I. Battery voltage (V) 1. Open circuit voltage (OCV) The voltage of the lithium battery when it is not connected to an external circuit or load can generally be tested with a multimeter. 2. Operating voltage (WV) The potential difference between the positive and negative terminals of the battery under applied load, that is, when there is current flowing through the battery in the circuit. When the...

What are the characteristics of industrial UPS power supply

Aug , 29 2023

Industrial UPS power supplies need to focus on the ability to operate in high-temperature environments. The design of components must adapt to the operational requirements of the industrial environment, adapt to high temperature and humidity, and also be able to cope with the corrosion of corrosive gases on the system. Under various operating conditions and continuous full load operation, industri...
