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 »
2017 Chevrolet Bolt EV: The era of long-range, mid-priced EVs is here
The 2017 Chevrolet Bolt EV will surely be remembered as a milestone model in automotive history – and hopefully for more than just the hype that heralded it. For several years, the punditocracy has been saying that the “killer app” that would bring electromobility to a “tipping point” and build that all-important “critical mass” would… Read more »
Navigant Research analyzes how transition to shared vehicles will effect energy markets
By Scott Shepard, Senior Research Analyst at Navigant Research’s Transportation Efficiencies program Smartphones have really changed the way things get done, and the continuous and sometimes overwhelming revolutions enabled by our hand-held devices are only just beginning. The transformations still to come include the basic process by which people and things are moved. The addition… Read more »
AIMPLAS heating system for EVs reduces energy consumption by 30%
The research association AIMPLAS, the Plastics Technology Centre, together with other partners of the EU project JOSPEL, has developed a heating system for EVs that could reduce energy consumption by up to 30% compared to conventional heating systems. The system is based on the Joule effect (also called resistive or ohmic heating), by which electrical… Read more »
New Farasis lithium-ion pouch cell balances power and energy density
Farasis Energy has introduced a new lithium-ion battery cell that it says provides increased energy density, greater power, improved cooling technology and longer service life. The new 32 Ah pouch cell offers 10% more energy density and capacity compared to previous Farasis designs, and is capable of continuous discharge at a 4C rate with a… Read more »
Kreisel Electric’s MAVERO home energy storage system
Austrian battery manufacturer Kreisel Electric has introduced the new MAVERO wall-mounted home energy storage system. The Li-ion battery packs are available in four different sizes, with usable capacity ranging from 8 kWh to 22 kWh. The system’s discharge power ranges from 4.8 to 9.6 kW, and voltage ranges from 288 to 384 V. Efficiency is… Read more »
