The most interesting part of the 2014 Cadillac ELR is the software
We often hear automotive engineers talk about the need for a better understanding of the components of an EV. Some have said that there is an inherent inefficiency in many systems because the parts – like the battery cells, motors and inverters – have historically been developed independently of each other and then integrated together….

New Linear Technology power manager and charger works with several battery chemistries
Linear Technology has introduced a versatile power manager and multi-chemistry battery charger. The LTC4020 features ±0.5% charge voltage regulation and operates across a 4.5 to 55 V input voltage range, with output voltage up to 55 V. Coupled with three selectable termination algorithms, the controller can handle a variety of battery-stack voltages and chemistries. A… Read more »
New paper: Planning public charging networks is NP-hard
A group of researchers from Hong Kong Baptist University have released a paper that addresses the problems of planning the locations of public charging stations. In Electric Vehicle Charging Station Placement: Formulation, Complexity, and Solutions, Albert Lam et al look at the issue from the standpoint of Hong Kong, which has ambitious plans to encourage… Read more »
EVSE: the low-hanging fruit of smart city buildout
How installing a few charging stations is more of a long-term solution than meets the eye. We often hear about the need for smart cities, smart grids, and sustainability in general, but what does it really mean? How can we ever hope to build a smart and sustainable global ecosystem, considering the energy-consuming path that… Read more »
ams introduces improved architecture for cell monitoring and balancing
ams AG, an Austrian provider of analog ICs and sensors, has introduced a simpler and more robust method of monitoring and balancing cells in lithium-ion battery systems. The company has implemented the new architecture in a highly integrated chip, the AS8506, to perform distributed cell monitoring and balancing operations for stacked cell modules, including Safe… Read more »
Jaguar Land Rover seeks partner to develop hybrids
Like all the world’s automakers, Jaguar Land Rover is working hard to build cleaner cars. The European Commission’s emissions mandate requires a 20% reduction in fleetwide emissions by 2015. The venerable British brand isn’t exactly famous for fuel-efficient models – the rugged Defender safari mobile and Inspector Morse’s enormous red Mark 2 come to mind…. Read more »
Around the EV world in 1,000 blog posts
This is my 1,000th blog post for Charged and, since I don’t care for Champagne, I’ll celebrate the occasion by writing myself a little pat on the back and a fond recap. Since I began in October 2011, I’ve written a couple of these every day, and I’ve covered a huge variety of topics, including:… Read more »
Battery makers expect to cut prices in half by 2020
Executives at two leading battery makers said this week that the cost of lithium-ion batteries is steadily declining, and could well drop to half of today’s price by 2020. “We have an internal target to go down by at least a factor of two by 2020,” said LG Chem Power CEO Prabhakar Patil, at this… Read more »
The challenges of battery state of charge measurements
Your BMS’s fuel gauge is lying to you. Here’s why that’s not a big deal. Battery management systems (BMSs), and the fuel gauges in them, are a part of daily life for almost everyone. You’ll find them in vehicles, laptops, cell phones, grid-attached energy storage – basically, anything that does work and needs to be plugged in,… Read more »
