Policies to promote electric vehicle deployment
The pulse power test allows observing the change of voltage Δ V due to a change in the current Δ Ι, and therefore the ratio (18.1) R = Δ V Δ I, gives the ohmic resistance R during charge and discharge of the battery system. This is illustrated in Figures 18.1 and 18.2, where a pulse current profile results in a corresponding measured voltage …
National Blueprint for Lithium Batteries 2021-2030
UL Solutions audits and certifies large battery repurposing facilities to UL 1974, the Standard for Evaluation for Repurposing Batteries, to help ensure that used electric vehicle batteries are safe for their intended second-life applications.
1. Introduction. In 2019, 83% of primary energy supplies still came from fossil fuels, namely, oil, nature gas and coal [1], which accelerated air pollution such as global warming by emitting tons of CO 2.The desire to build a society with low-carbon or zero-carbon emission urges the intensified use of renewable energy sources including wind and solar energy.

Standards and Test Procedures
Abstract: Recently, the fast frequency response (FFR) service by large-scale battery energy storage systems (BESSs) has been successfully proved to arrest the frequency excursion during an unexpected power outage. However, adequate frequency response relies on proper evaluation of the contingency reserve of BESSs. The BESS FFR reserve is …
The Chinese government attaches great importance to the power battery industry and has formulated a series of related policies. To conduct policy characteristics analysis, we analysed 188 policy texts on China''s power battery industry issued on a national level from 1999 to 2020. We adopted a product life cycle perspective that …
Lithium-ion batteries (LIBs) with relatively high energy density and power density are considered an important energy source for new energy vehicles (NEVs). However, LIBs are highly sensitive to temperature, which makes their thermal management challenging. Developing a high-performance battery thermal management system …
