If you've ever wanted to use a Hydra at home, but wanted to wire it directly to a dedicated circuit or plug it into a dedicated 240 volt outlet instead of connecting it to a host EVSE, then your day has come!
The Hydra II EVSE variant boards have now arrived in the store! This variant trades the inlet handling and outlet proximity signal for a GFI and a real-time clock chip. With it, you can build your own double-head EVSE capable of connecting to two cars simultaneously and either charging both with half the current allowance of your circuit or sequencing the two vehicles automatically.
Not only that, but the real-time clock chip allows you to set up to 4 events, each with a time-of-day and a day-of-week mask - enough to set up two independent time-of-use charge schedules - perfect for weekday and weekend scheduling (if you want more, you can simply change a constant in the firmware and re-upload). There's even timezone support so that the clock will automatically correct for daylight savings time.
As with the original Hydra II, if you order the assembled and tested board, then you can complete your Hydra without doing any soldering at all (you can buy a pre-wired button from the OpenEVSE store - just tell Chris you need long wires), and it takes about a half a day of basic mechanical assembly.
