Electric vehicle (EV) charging infrastructure will play a critical role in decarbonization during the next decades, energizing a large share of the transportation sector. This will further increase the enabling role of power electronics converters as an energy transition technology in the widespread adoption of clean energy sources and their efficient use. However, this deep transformation comes with challenges, some of which are already unfolding, such as the slow deployment of charging infrastructure and competing charging standards, and others that will have a long-term impact if not addressed timely, such as the reliability of power converters and power system stability due to loss of system inertia, just to name a few. Nevertheless, the inherent transition toward power systems with higher penetration of power electronics and batteries, together with a layer of communications and information technologies, will also bring opportunities for more flexible and intelligent grid integration and services, which could increase the share of renewable energy in the power grid. This work provides an overview of the existing charging infrastructure ecosystem, covering the different charging technologies for different EV classes, their structure, and configurations, including how they can impact the grid in the future

We study the current estimates of Bc→Bsπ to extract the fragmentation fraction fc/fs at the LHCb. A rather robust estimate of Br(Bc→Bsπ) based on factorization and lattice results for the form factor gives fc/fs∼0.056 with a 16% error. We also revisit the extraction of fs/fd using B→Dπ instead of the theoretical cleaner but more suppressed channel B→DK. We also find a tension on the predictions of Br(Bc→J/ψπ) and Br(Bc→Bsπ) considering the measurements of these modes at LHCb, and find that, within a 23% uncertainty, only the lower end of the current prediction range Br(Bc→J/ψ)∼0.4%−1.7% would be consistent with the LHCb measurements.
