BMW has been taking its share of criticism in the EV press lately, because of its lack of new plug-in models, and because it seems to the biggest loser from Tesla’s gains in the luxury sedan segment. But don’t count the Bavarians out just yet. The i3 is as popular as ever, especially in Europe… Read more »

Revolve Technologies unveils new fuel cell range extender
UK-based Revolve Technologies has developed a new fuel cell technology using a printed circuit board (PCB) construction. The company says its PCB fuel cell stack will lower system costs, deliver reduced weight for a given power output and provide a more flexible form factor, compared with current systems. Revolve’s fuel cell range extender module is… Read more »
Voith’s electric drive system for buses incorporates self-learning energy management
Drivetrain specialist Voith has designed a drive system that uses self-learning energy management to increase efficiency and range. Although the system was originally designed for a Solaris Urbino Bus, it is compatible with many other battery technologies and vehicles, including articulated buses. The system will be introduced to the public at the upcoming IAA Commercial… Read more »
US energy regulators issue a new storage rule with important implications for EVs
In March, the Federal Energy Regulatory Commission (FERC) issued a rule requiring regional electrical grid operators to revise their regulations pertaining to energy storage and how storage resources might participate in electricity markets. Okay, it sounds a bit wonky, but FERC’s decision is an important policy shift that could have a big impact on EVs…. Read more »
ARPA-E to award $30 million to develop grid energy storage technologies
The DOE’s Advanced Research Projects Agency-Energy (ARPA-E) is wasting no time after its recent near-death experience (the president’s proposed budget would have eliminated the agency, but cooler heads in Congress prevailed): it has announced up to $30 million in funding for a new program called Duration Addition to electricitY Storage (DAYS), which has a goal… Read more »
Musk says Tesla Semi may have a 600-mile range
Now that the furor over Elon Musk’s rudeness to those poor little stock analysts has faded, let’s look at some of the interesting information that was revealed on Tesla’s quarterly earnings call. One of several tantalizing tidbits dropped by Musk: he expects the production version of the Tesla Semi to have a 600-mile range. When… Read more »
A closer look at energy consumption in EVs
When it comes to factors that affect energy consumption in EVs, the big kahunas are weight and wind resistance (aka CdA), but there are other factors that can have a surprisingly outsized effect and that tend to be overlooked, such as the use of climate control (AC, of course, but especially heat). Conversely, one factor… Read more »
Battery management device reconfigures battery modules to extend EV range
A pair of Vanderbilt University researchers have developed a battery management device that could increase the useful range of a battery pack by controlling each cell individually. Ken Pence, Professor of the Practice of Engineering Management, and Tim Potteiger, a PhD student in electrical engineering, used the open-source Tesla battery to model their technique, adding… Read more »
BorgWarner cabin heater extends driving range for new EV
BorgWarner has announced that it will supply its high-voltage positive temperature coefficient (PTC) cabin heating technology for an unspecified new EV model from a global automaker. BorgWarner’s technology is designed to provide rapid cabin heating while making the most efficient possible use of energy in order to conserve battery power. Unlike legacy vehicles, EVs don’t… Read more »
Solving the energy density challenge with single wall carbon nanotubes
Sponsored by OCSiAl Group Li-ion batteries represent the most dynamic and fastest growing battery market, with total sales of $10 billion in 2015 [i]. Historically, the primary challenge for battery manufacturers has been the constant demand for greater energy density, both volumetric and gravimetric. Li-ion’s dramatic rise is in large part due to solving this challenge more… Read more »
