oneDRIVE of a kind: KLD Energy’s new propulsion system

In August 2013, KLD Energy announced that it has received official UN and IEC certification for the battery pack solution of its proprietary electric drive system. The announcement marked the end of a five-year development effort and the beginning of high-volume production for the company’s ultra-efficient turnkey oneDRIVE propulsion system.  There are hundreds of different… Read more »

The new A123 looks a lot like the old A123: Q&A with Jeff Kessen

Start-ups are tough. The majority of them do not succeed, particularly those built around new technologies in burgeoning industries. Nowhere is this more evident than in the EV industry. Even with political support and government grants, many companies have miscalculated the market and the capital required to make it into the black.  In October 2012,… Read more »

Leyden Energy’s Li-imide electrolyte and the rise of start-stop vehicles

Battery start-up Leyden Energy plans to profit from the forecasted groundswell at the bottom of the electrification ladder: start-stop vehicles The average person may see the trademarked Li-imide logo and rush to the nearest convenience store to try a tangy new soft drink. However, you, being a somewhat chemistry-savvy electric vehicle enthusiast, know that Li-imide’s likely… 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 »

The infrastructure behind the infrastructure: Bosch invests in EVSE

Bosch is taking the Electric Vehicle Supply Equipment (EVSE) market very seriously, investing heavily in the infrastructure behind the infrastructure One of dozens of indicators that suggest plug-in vehicles are here to stay is that companies like Bosch – the multinational engineering and electronics powerhouse – are jockeying for an early lead in the charging… Read more »

Connecting the dots: EV charging hardware, software and services

More and more organizations are finding that it makes sense to offer EV charging to their employees and/or customers. However, installing and administering the charging stations, especially across a large enterprise, can be a complicated proposition. Not the least of the headaches is finding a way to quantify the return on investment (ROI) in charging… Read more »

Web of Power: Spider9’s Operating System for Energy

Spider9 weaves a matrix for stationary energy storage and shows that when it comes to fitting battery technology into electric vehicles, it’s not all for one and one for all. Many real-world technologists and engineers take inspiration from the worlds of science fiction, where recurring themes of systems theory take shape in the Grid of… 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 »
