Why are 5G base stations important?
The denseness and dispersion of 5G base stations make the distance between base station energy storage and power users closer. When the user's load loses power, the relevant energy storage can be quickly controlled to participate in the power supply of the lost load.
Does a base station energy storage model improve the utilization rate?
