I would consider triple digit Fahrenheit temperatures
to be extreme temperatures for motorcycling in and we had a 46C (115 Fahrenheit)  day in Sydney last summer so we experience conditions like the American West, we just don't consider them normal,  as they are from a global perspective, extreme.

I stand by my comment that on the road you need extreme (>100F) temperatures to overheat the battery or very hard/fast riding. Judging by comments across these forums there are very few people who experience battery overheating in their Zeros on the road and if they do,  it occurs in the conditions I've already stated.

The non-IPM motors will overheat easily under frequent acceleration... I would overheat the local demo FX in under 5 minutes just riding around town.

2 different things : motor and battery.
Easy to overhear the motor part, just have to accelerate hard many times... But no effect

Overheat the battery is other thing. Never append on my zero S since 8 month riding / racing. I will take care about this point next time to record all stats (heat during the 20min track, cooling with/without charge during standby before next track, external temp...)

Hi evtricity,

is it possible to make a small youtube movie while charging a Zero with the 3.3 kW and the 6.6 kW fast chargers?

ps. we had a great time down under 
we really loved the relaxed and helpfull way of living in Australia.

Yes, with the help of a fellow Zero owner who works in video production, we will be making a video showing the charging process with the fast chargers.

hi evtricity,

great

If you need any west coast USA testers still I'd be interested, if not, how is the USA testing going?

[42Cliffside]

Ha. Not in sydney, go far west for conditions closer to the west usa...

[evtricity]

Thanks for the offer to test 42Cliffside but we're not going to add any more USA testers. The locale testing in the USA and Europe was to help us understand customs and delivery issues as well as power and adaptor requirements and we've got a good understanding of those for the USA now.

Into the second week testing in Florida and it is going well with our 6.6kW charger being run on J1772 and NEMA 14-50 sockets with our tester also recently upgrading to the latest Zero firmware. No issues at this time.

We expect to be shipping production chargers to the USA from w/c 12th June if testing and case powdercoating continue to proceed to plan.

In terms of high temps in west USA, our chargers will run at full power up to 150F (65C) ambient, so you can run them in Death Valley if you wish! #hotenoughforyou 

[42Cliffside]

sweet, that's awesome.
I will be ordering a 6600+W unit when I get my bills in order. that could be a while...

fyi, i prefer anodizing to powder coating...

[evtricity]

Unfortunately, the gloss anodising was four times more expensive and would took another week so I decided to go with the powdercoating for the first batch.

[swavess]

I can't wait for mine to arrive, looks like it cleared customs yesterday.  As I live in NV, I'll be operating in hot temps this summer, but I'm not concerned about it. Extreme temps take their toll on all equipment....and operator, I don't see this as an issue at all.

I've had a request over the weekend to build a triple charger. We have indeed built a case for these and done some initial testing with the unit capable of 13.2kW (AC) and 12kW DC. The charger needs to be wired to bypass the 100A charge fuse to supply this amount of power.

Who would be interested if we made a "triple" 13.2kW charger available? Cost would be ~AUD2390. That's USD1775 and EU1575 based on current exchange rates. Price includes worldwide delivery but excludes local taxes and import duties. Weight is 8kg.

The unit would be best suited for use in Europe, Australia, New Zealand etc where three phase power is readily available but could also be used in the USA using high powered J1772 stations (eg. 80A) or multiple J1772 stations.  This charger would need to be integrated by the purchaser to bypass the 100A charge fuse e.g. connected to the Sevcon controller battery terminals.

For most Zero owners we strongly recommend getting the 6.6+kW stations as it provides close to the maximum power that the charge fuse supports when used in parallel with the onboard charger. With charge times in the 1-1.5 hour region from empty on most Zero S/DS/SR/DSR models the 6.6kW+ charger makes road trips and touring achievable. While, the 3.3+kW is certainly better than the onboard by itself, with 2+ hour charge times from empty it's not as well suited for 200+km (120 mile) road trips. The triple charger is for those who want to go to the next level and are comfortable connecting the charger to bypass the charging fuse and understand the implications of charging at or over the "1C" charge rate and the sub hour charging from empty that it delivers.

Triple charger prototype photos attached.

Triple isnt 9.9kw

Triple isnt 9.9kw

Triple is our code name for the levels in the charger. Single has one level, double has two levels, triple has three levels.

The default setting on our chargers is 15A per level so a single charger in the USA (220V) is 15A x 220V = 3.3kW, double charger is 30A x 220V = 6.6kW and triple charger is 45A x 220V = 9.9kW. We can increase the input current limit up to 20A, so a single charger can be 20A x 220V = 4.4kW, double charger can be 40A x 220V = 8.8kW and triple charger can be 60A x 220V = 13.2kW.

In Europe where 3 phase 32A stations are abundant, the triple charger could run at 58A (19.3A on each phase) x 230V = 13,340kW AC!

Ok ! Very clear
Thanks
