Why battery energy storage moving to higher DC voltages (Part-1)

Nov , 08 2022

Today, most utility-scale solar inverters and converters use 1500 VDC input from the solar panels. Matching the energy storage DC voltage with that of the PV eliminates the need to convert battery voltage, resulting in greater space efficiency and avoided equipment costs. The evolution of battery energy storage systems (BESS) is now pushing higher DC voltages in utility scale applications. The Woo...

Analysis of BMS (Battery Management System) Protection Mechanism and Working Principle

May , 06 2023

I. BMS function First, we'll detail its four main functions. (1) Perception and measurement Measurement is the perception of the state of the battery This is the basic function of BMS, including the measurement and calculation of some index parameters, including voltage, current, temperature, power, SOC (state of charge), SOH (state of health), SOP (state of power), SOE (state of 能源). SOC can be c...

Basic knowledge of filters

Jun , 21 2023

The Line filter is a filter circuit composed of capacitance, inductance and resistance. A filter can effectively filter out a specific frequency point in the power line or frequencies outside of that frequency point, obtaining a specific frequency power signal or eliminating a specific frequency power signal. A filter, as the name suggests, is a device that filters waves. Wave "is a very broad phy...

Difference between kVA and kw

Mar , 15 2025

kVA is the unit of apparent power and kw is the unit of active power. In alternating current, apparent power does not indicate the actual power consumed in the circuit, but rather the maximum power that can be supplied or the maximum active power consumed in an alternating current circuit. In the case of active power, it is the power needed to enable the equipment to work properly, such as the ele...
