The difference between the first, second, and third levels of distribution boxes

Jun , 22 2024

What do the primary, secondary, and tertiary boxes of a distribution box mean? This is a relative issue. Let's make a hypothesis: a newly built residential area introduces a 10kV incoming line and builds a distribution room. The outgoing line from the low-voltage end of the transformer is 0.4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distrib...

Irreversible lithium evolution of LiFePO4 batteries at low temperatures and its effect on battery performance degradation

Dec , 07 2024

Lithium evolution is the main failure problem faced by lithium-ion batteries during low temperature charging. Due to the low diffusion rate of lithium ions in the solid phase of graphite particles and in the liquid phase of the electrolyte at low temperatures, the negative polarization increases during charging and lithium evolution occurs, and the precipitated lithium metal is divided into revers...

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...
