Eguana and LG Chem partner on residential energy storage system
Tesla may have some competition in the residential storage market. Battery giant LG Chem has partnered with Eguana Technologies to develop a modular energy storage system called AC Battery. AC Battery is targeted at homeowners who want to store electricity from solar panels for later use. However it could also be aggregated for small commercial… Read more »
Maxwell Technologies introduces 24-volt versions of ultracapacitor-based Engine Start Module
As every truck driver or heavy equipment operator knows, diesel engines can be difficult to start in low temperatures, or after not being started for long periods. Maxwell Technologies’ Engine Start Module (ESM) is an ultracapacitor-based system that takes over the engine cranking function and remains fully charged, even if battery voltage drops. Now Maxwell… Read more »
2016 Cadillac ELR gets a price cut and performance upgrades
The Cadillac ELR has always been a bit of an odd duck. When it went on sale at the end of 2013, most of the media, including Charged, found it to be a fine vehicle, but some were skeptical that buyers would be interested in paying $75,000 for what is basically a luxury version of… Read more »
ORNL researchers develop Virtual Integrated Battery Environment design tool
As part of the DOE’s Computer Aided Engineering for Batteries (CAEBAT) project, scientists at the Oak Ridge National Laboratory (ORNL) have developed an open-architecture battery modeling framework that integrates multi-physics and multi-scale battery models. The Virtual Integrated Battery Environment (VIBE) allows researchers to test lithium-ion batteries under different simulated scenarios. The physics phenomena of interest… Read more »
Assisted steering system uses individual wheel motors for more efficiency and better range
Modern automobiles are complex beasts, with numerous subsidiary systems that consume energy. In an EV, more energy consumption means reduced range, so it can be well worthwhile to study more efficient ways to power the various accessories. One of these accessory systems is assisted steering, which reduces the physical effort required for the driver to… Read more »
Is String Cell battery technology the future for EVs?
When it comes to finding a way to charge EVs more quickly, human ingenuity has come up with some pretty wide-ranging solutions, from battery-swapping to flow batteries that store energy in tanks of liquid electrolyte. The latest innovative idea comes from startup Tanktwo, and is called a String Battery. Tanktwo’s system replaces a vehicle’s battery pack with a container filled… Read more »
Does Tesla’s latest software update really end range anxiety?
The buildup was pretty big: earlier this week, Elon Musk’s tweeted that an upcoming software update for Model S would “end range anxiety.” The reality – announced at a press conference today – is neat, but perhaps not quite so game-changing. Software version 6.2, which is expected to be enabled in the next 10 days,… Read more »
The future of integrated inverters: Press-fit solderless interconnects and smarter design
Interplex, the complex assemblies expert, on power electronics, the automotive industry and the continuous drive for smarter design Power modules containing high-power insulated-gate bipolar transistors (IGBTs) are at the core of most modern inverters. These modules are the electronic muscle of the system. They perform all the switching, and they generate all the heat. But… Read more »
Quick Charge Power: Tony Williams on his journey into the EVSE business
EV advocate to charging entrepreneur You may remember a little Nissan LEAF battery controversy that popped up a few years ago. Beginning in May 2012, a handful of LEAF owners located in Phoenix, Arizona started posting on forums that, according to the car’s dashboard display, their batteries were losing capacity much faster than they were expecting….
