You've probably heard of the Renault Twizy. In fact, you may even have seen one scooting along your local high street covered in the local estate agent's branding. But I bet you've probably never heard of a small British firm called Symphony EV.

To be brutally honest, neither had we, but when it came to charging our own shiny new Twizy, we were left scratching our heads. We'd had a brace of Twizys only three years ago, you see, and we'd quite forgotten that they were charged via a three-pin socket rather than a public-infrastructure-standard Type 2.

Something needed to be done. Convincing the facilities department at our head office in Twickenham to move their equipment to uncover our car park's single 230V socket worked once, but I could sense that it wouldn't be fine tomorrow. Or indeed, ever again, which - naturally - sent me scurrying to Google. And who should pop up? You guessed it: Symphony EV.
