Increasing environmental issues, security of energy supply, drive research and development towards renewable energy sources (RES) worldwide. A key issue of RES, such as wind and solar resources, is intermittency. RES are not dispatchable, they exhibit large fluctuations, and are uncertain. The intermittency of RES can be absorbed by the hybrid combination of different RES [...]

Yes! All Li-ion cells and packs shipped must be tested to meet the Recommendations on the Transport of Dangerous Goods on lithium-ion batteries for air shipment, rules set by the United Nations (UN). The electrical test stresses the battery by applying high heat, followed by a forced charge, abnormal discharge and an electrical short. During [...]

Generating renewable electricity is an important way to reduce carbon dioxide (CO2) emissions and many countries are installing wind and solar power plants to help meet targets for cutting CO2. One drawback of these energy sources is their variability: the wind tends to blow intermittently and solar power is only available during the daytime. Hence [...]
