In the bad old days when the only batteries suitable for traction applications were flooded lead-acid and Ni-Cd types, the battery was the least efficient component of an EV powertrain, routinely delivering back only 50-70% of the amp-hours that went into charging it (aka the Coulometric efficiency). When you knew you were going to be… Read more »

European regulators reach provisional agreement to lower heavy-duty truck emissions 30% by 2030
The European Parliament and the Council have reached provisional agreement on a regulation that will set strict CO2 emission standards for trucks in the EU. Emissions from new trucks will have to be 15% lower by 2025 and 30% lower in 2030, compared to 2019 emissions. The text of the regulation still needs to be… Read more »
Researchers explore proton-hopping mechanism to improve EV batteries
Researchers at Oregon State University have shown that a chemical mechanism known as proton-hopping may provide a new method of energy storage for EVs and other high-power applications. “Coming up with Faradaic electrodes that afford batteries energy density and capacitors power with excellent cycle life has been a big challenge. So far, most of the… Read more »
Rivian secures $700 million in new investment round led by Amazon
Amazon will lead a $700-million investment round in EV startup Rivian Automotive. Also investing in this round is Rivian’s long-term investment partner, Saudi auto distributor Abdul Latif Jameel. Although it was reported earlier that GM was also in talks with Rivian, the automaker is not involved in this round. Rivian has been raising eyebrows since… Read more »
Tesla and Jeff Dahn patent new battery cell chemistry
Tesla’s battery research group in Halifax, which is led by battery superstar Jeff Dahn, has applied for a patent on a new battery cell chemistry that promises to deliver faster charging, longer life and lower cost. In the application, entitled “Novel battery systems based on two-additive electrolyte systems,” Dahn and his team explain that adding… Read more »
ClipperCreek drops price of CS Series EV charging stations
ClipperCreek has announced a $400 price reduction on its Liberty Plugin-enabled CS Series of charging stations. The Liberty-enabled CS Charging stations are ClipperCreek’s flagship access control models, and pricing has been reduced on all configurations from 16 to 80 amps. The new price is effective immediately. “The price reduction was made possible by a variety of… Read more »
Electrify America to use Tesla Powerpacks at some charging stations
Charging network operator Electrify America has announced plans to install battery storage units made by Tesla at over 100 of its charging stations. EA will deploy Tesla Powerpack systems consisting of “a 210 kW battery system with roughly 350 kWh of capacity” at over 100 charging stations. A modular system will allow EA to increase… Read more »
Tesla revises pricing options, reintroduces software-limited battery packs
After Tesla recently discontinued the 75 kWh versions of Models S and X, some speculated that it was a precursor to replacing the battery pack used in those models with a redesigned pack based on the newer 2170 cells used in Model 3. However, that doesn’t seem to be in the cards for the moment… Read more »
Electrify America’s high-powered charging stations are back online (Updated)
January 28, 2019. Original article posted: Electrify America’s high-powered DC charging stations are at the cutting edge of EVSE tech – only a couple of current EVs are able to use them at full power. Now a technical problem seems to have come up with the liquid-cooled cables that these ultra-fast chargers rely on. At the recommendation… Read more »
Top circuit protection considerations for DC fast chargers, a new class of high-voltage consumer electronics
DC fast charging isn’t just a godsend for EV drivers looking for a quick charge. It’s also an entirely new level of consumer electronics. “You and I, as members of the general public, have previously never had access to anything higher in voltage than what we see at home in our wall socket,” Tim Patel, Global… Read more »
