China renews EV subsidies
China has renewed subsidies for the purchases of new energy vehicles (EVs and PHEVs) for another three years. The country’s Finance Ministry announced this week that it will offer up to 60,000 yuan ($9,800) for the purchase of an EV, up to 35,000 yuan for a PHEV, and up to 500,000 yuan for an electric… Read more »
The challenges of battery state of charge measurements
Your BMS’s fuel gauge is lying to you. Here’s why that’s not a big deal. Battery management systems (BMSs), and the fuel gauges in them, are a part of daily life for almost everyone. You’ll find them in vehicles, laptops, cell phones, grid-attached energy storage – basically, anything that does work and needs to be plugged in,… Read more »
Plug-in fleets: small challenges, huge savings
Four plug-in truck companies talk to fleet managers about electrification opportunities Plug-in vehicles are different. Aside from the obvious changes in technology, they present a different financial model for corporate number crunchers. This means some challenges for those pitching EVs and PHEVs to fleet operators. Fortunately for the EV industry and the fleets of the… Read more »
Resonating with the OEMs: WiTricity’s wireless energy transfer technology
WiTricity hopes to leverage a wireless energy transfer breakthrough out of MIT into a commercial solution with far-reaching potential Inside a standard electrical transformer are two coils that transfer power wirelessly. They utilize the principle of magnetic induction, sending energy from a primary coil to a secondary coil without a direct electrical connection. Inductive chargers,… Read more »
A closer look at back electromotive force
Why motors generate and generators motor In a previous article I took a closer look at regenerative braking, and mentioned an old engineering saying that every motor is a generator and every generator is a motor (along with the caveat that some are more suited to the opposite purpose than others). This time around I’ll… Read more »
New study predicts a bright future for plug-ins in Brazil
Brazil is poised to become the next EV hotspot, according to a new study from Frost & Sullivan. The company’s Strategic Analysis of Brazil Electric Vehicle Market [sic] estimates that 35 plug-in models will be launched in Brazil, and sell some 80,877 units by 2020. PHEVs will account for more than 70 percent of the… Read more »
