6 EV infrastructure lessons we can learn from Norway

“When you get off the plane in Oslo, Norway, it is like entering fairytale land for people in the EV industry,” says Rami Syväri of charging network operator Fortum. Thanks to hefty government incentives – including zero import taxes, charging incentives and bus lane access – Norway has quickly catapulted its EV market from early-adopter… Read more »

Second life: Spiers New Technologies develops advanced battery classification techniques

Spiers New Technologies (SNT) is just over a year old, but its founder has been focused on developing the market and technology for secondary-use batteries as long as anyone in the business. Dirk Spiers is one of the more passionate figures in the EV industry. Like many entrepreneurs, he seems to have a clear view… Read more »

Advancing BMS: Linear Technology launches its fourth-generation battery stack monitor

Engineers use battery management systems (BMS) to prevent problems that occur in Li-ion batteries when they are over-charged or over-discharged, including premature capacity loss and thermal events. A BMS ensures precise control and keeps the individual cells balanced, which is critical to extracting the most useful energy from a pack. Fortunately for EV systems designers,… Read more »

Q&A with Tesla’s lead motor engineer (Full Interview)

The principal motor engineer at Tesla describes why modeling and optimization is so vital to its design process. Creating a start-of-the-art electric vehicle requires a deep understanding of all the components. More importantly, it requires a continual process of analysis and optimization of the components to push the limits of driving range, efficiency, performance and… Read more »

Zero Motorcycles was forced to abandon DC fast charging option in 2013, Interoperability testing is needed

Editor’s note: After this article appeared in print, we received some feedback suggesting that the thesis is not clear enough. So, we’d like to point out a few things at the beginning. Today’s DC Fast Charging installations are very reliable. If you buy a production EV, such as a Nissan LEAF or BMW i3, it is unlikely that you will… Read more »

Can Tanktwo redefine the battery pack with big data?

A Finnish-American start-up with ambitious goals wants to change how we think about batteries. The concept of an EV that supports the quick removal and replacement of a discharged battery pack was all the rage about 5 years ago. Since then, however, various systems have been attempted and subsequently abandoned by companies like BetterPlace, Renault,… Read more »

Paraclete Energy says its low-cost silicon nanoparticles can at least double your current anode capacity

Silicon has a theoretical charge capacity ten times higher than typical graphite. That is why a mind-blowing number of researchers are working towards replacing more and more of the graphite used in today’s lithium-ion battery anodes with silicon. In the last issue of Charged, we discussed Tesla’s announcement that it had begun to use small… Read more »

In one year, Tesla added over 850 public charging sites in the US

Tesla’s large network of proprietary public charge points continues to rapidly expand. In addition to the high-power Superchargers placed along well-traveled highways, the company has been deploying destination chargers at locations where drivers would want to stay for several hours at a time: like hotels, ski resorts, and restaurants. According to data in PlugShare’s latest… Read more »

DC Fast Charging maps highlight differences between Tesla and CHAdeMO/CCS rollouts

Tesla touts its Supercharger network as a no-compromise solution for electric road trips, and has strategically placed Superchargers along well-traveled highways. Elon Musk himself has embarked on a coast-to-coast adventure in a Model S to demonstrate that it can be done in about the same timeframe as with any other vehicle. On the other hand,… Read more »

Tesla tweaks its battery chemistry: a closer look at silicon anode development

In mid-July, Tesla Motors made a trio of Model S update announcements. The new options included a 70 kWh rear-wheel-drive base model, an upgrade for the high-end battery pack from 85 to 90 kWh (providing about a 6% increase in range), and Ludicrous mode, which offers a 10% improvement in the car’s 0 to 60… Read more »
