Click to download pdf version. Four California state agencies and the independent powergrid operator have released a new plan and vision for California’s energy future in advance of the Air Resources Board consideration of a first-in-the-nation rule requiring that a third of California electricity come from renewable sources by 2020.
So when he called me on a Friday afternoon in the summer of 2021 to propose an article delving into the complexities of the global transition to electric vehicles, I knew that he’d do the research at a deeper level than any tech journalist, and that he’d explore angles that wouldn’t even occur to them. Take power-grid transformers.
Should you use one of them to charge your Electric Vehicle (EV)? The Difference Between AC and DC Current Electrical current comes in two forms: alternating current (AC) and direct current (DC).

Grid-connected battery farms back up renewables when the sun is not shining or the wind is not blowing and are considered important to help integrate clean energy into powergrids. This is particularly important for China, which has minimal natural gas capacity, a more flexible power source than slow-ramping coal plants.

This rapid charging capability is a significant step forward, as it opens up new possibilities for the use of sodium-ion batteries in various applications, including electric vehicles and other advanced technologies. One of the most exciting aspects of this new battery technology is its potential impact on electric vehicles (EVs).
Today’s vehicle designs proliferate with sensitive electronics, including electronic controls, infotainment, sensing, battery packs, battery management, electric vehicle powertrains, and on-board chargers. Due to the connection to the grid, on-board charger protection from voltage surges using unique components is essential.
If you’re filling up a car that has an internal combustion engine (ICE), you only need to distinguish between the gas and diesel pump. For drivers of electric vehicles (EVs), however, there are more options to choose from. If you want to use your devices abroad, you’ll typically need an adapter or even a transformer to draw power.
GM has announced plans for public sales in 2010, and almost every carmaker now says it will sell PHEVs or highway-speed battery electric vehicles (BEVs) sometime after 2010. This is from "Commercializing Plug-In Hybrids" (pdf), the current CalCars 24-slide presentation about PHEVs available along with other documents at CalCars Downloads.
