When discussing energy storage projects, the terms MW and MWh appear frequently. Many people are confused by these two abbreviations: what exactly do they mean and what's the difference? Simply put, MW is a unit of power, and MWh is a unit of energy. In power systems, MW and MWh are core metrics for describing system capabilities. Understanding the difference between these two concepts is as cruci...
Designing a battery energy storage system (BESS) is a critical step toward achieving energy independence, optimizing renewable energy use, and ensuring backup power. Whether for residential, commercial, or industrial applications, a well-designed BESS can significantly reduce electricity costs, enhance grid stability, and contribute to a sustainable future. In this blog, we’ll walk through t...
Common battery packs generally use three cooling methods: liquid cooling, air cooling, and natural cooling. Battery cells are quite sensitive to temperature, with an optimal operating temperature generally between 15 and 35°C. Temperature variations cause varying degrees of capacity reduction in lithium batteries; specifically, at -10°C, usable capacity is 70%; at 0°C, it's 85%; and at...
User-side energy storage, as the name suggests, is an energy storage system installed on the electricity user's side, widely used in industrial and commercial parks, high-energy-consuming enterprises, and residential communities. It, along with power-side energy storage and grid-side energy storage, constitutes the three major application areas of energy storage, but its **core characterist...
Recently, China's first large-capacity all-solid-state battery production line has been completed and entered the small-batch testing and production stage. So, what exactly is an all-solid-state battery? Why is it considered a key driver of the future development of the new energy vehicle industry? Today, let's take a closer look at the several rounds of upgrades all-solid-state batteries h...
