After a slow start, Tesla’s sales are starting to take off in the world’s largest auto market. The company sold 10,400 vehicles in China in 2016 – triple the previous year’s figure – and sales for the first three months of 2017 have put it on track to double that this year. China represented around… Read more »

Tesla pays for Destination Chargers that charge other automakers’ EVs
In addition to its Superchargers, Tesla has been installing Level 2 Destination Chargers at locations such as hotels and restaurants – over 5,000 so far. Tesla installs the chargers for free, and the host covers the electric bill. In the US, Tesla chargers use a proprietary connector, so theoretically only Tesla vehicles can use them…. Read more »
Two thumbs up for the Chevy Bolt EV
Here at Charged, we usually write about technical matters and industry trends, and leave the car reviews to others. However, after spending a week with the Chevy Bolt EV, I am moved to write not just a review, but a rave. I’ve driven pretty much every EV that’s widely available in the US, and there’s… Read more »
Alta Motors says its electric dirt bike has world-class energy density
Alta Motors claims that its dirt bikes have a battery pack with energy density that’s among the highest of any production vehicle. With help from Scheugenpflug’s custom production equipment and Wevo-Chemie materials, the motorcycle builder says its thermal design was the key to achieving that. Seven years ago, a group of motorcycle and off-road dirt… Read more »
MSC’s laminated steel and aluminum will reduce noise and vibration while cutting mass
When it comes to EVs, every pound matters. There is a direct relationship between a vehicle’s weight and the requirements of its expensive battery back, so automotive engineers will explore every possible measure to reduce vehicle mass. However, one of the ways that engineers have traditionally achieved desirable properties in the domain of Noise, Vibration,… Read more »
Tesla talking to other automakers about sharing Supercharger network
Tesla has brought up the idea of opening up its Supercharger network to other automakers several times over the years, but a recent comment by CTO JB Straubel has fueled conjecture that talk may soon evolve into action. Speaking at the Midwest Renewable Energy Association’s recent Energy Fair in Wisconsin, Straubel said, “For things like… Read more »
Workhorse CEO on the company’s new plug-in hybrid pickup truck and its expansive plans for the future
We all acknowledge the absurdity of ignoring an elephant, when one is present in the very room in which important matters are being discussed, but what about a hulking, jacked-up, V8-powered monster truck? Tesla permanently changed the conversation about EVs when it electrified a sporty two-seater, a luxury sedan and a crossover SUV, but few… Read more »
WattZilla’s launches new EVSE trade-in program as it’s Black Mamba and Wall Wattz receive safety certification
Black Mamba The last time Charged spoke with WattZilla’s Frank Gangi, he teased the company’s Black Mamba as “a lightweight EV charging cord that looks like a snake that ate a rat.” Don’t be put off by the namesake – as Gangi tells it, the Black Mamba is a carefully designed, lightweight charger that packs… Read more »
The technical reasons Tesla would limit supercharging speed, and other practical charging considerations
Recently, a bit of a kerfuffle kicked up when a Tesla Model S owner noticed that the maximum charge rate for his car on the Supercharger network had suddenly been cut from 120 kW down to 90 kW, apparently the result of too many fast charge cycles. Tesla’s explanation was, essentially, that many things can… Read more »
Wire bonding for EV batteries and inverters: application and process tips from Hesse Mechatronics
Sponsored by Hesse Mechatronics All electronic devices need to be connected electrically (and mechanically) and there are numerous ways of completing this task. Wire bonding is one type of interconnection. There are three types of wire bonding: thermocompression, thermosonic and ultrasonic. We will focus on ultrasonic wedge bonding with aluminium wire and discuss the wire bonding process… Read more »
