Workplace charging

Hmmm, now my limited understanding of the regs and AS3000 leads me to believe that a licence is only required for fixed instalations over 32V AC or 110V DC. An EV seems to me to be a plug in appliance, which does not require a licence to be worked on but must be tested and tagged for compliance to ...

QUOTE] I think AEVA policy should include a statement saying that we do not recommend connecting anything that does not comply with regulation. In fact it should be actively discouraged.

Even if the the charger is drawing a full 15A in most cases you still have another 5A to play with when you consider most GPO circuits are protected by a 20A CB.

You could use an adaptor cable so you can plug your charger into any regular 10amp outlet

200km @ 100kph ute, possible?

As Matt says, it is certainly doable.
In the tray of a ute you have plenty of room to fit batteries.

military spec high nickel wiring

I haven't heard of nickel electrical cable. Nickel has quite a high electrical resistance so perhaps it is used for a very special applications such as high temperature wiring or similar? Most electrical cables are copper with the finer the standing the more flexible the cable. Tin plated copper str...

200km @ 100kph ute, possible?

Sure it is possible with lithium but very difficult (if not virtually impossible) with lead acid. Having said that you would need quite a large/expensive pack for the sort of speed and range you are looking at. The magic equation goes like this- Speed/max.range per charge = x dollars More speed and ...

Paralleling batteries

Also the blocks are good for virtually any "regular" shape but not irregular shape where the cells are different distances apart. I am not sure what you mean by- "but not irregular shape where the cells are different distances apart"? Cells can be assembled into sub-pack batteries which may be a di...

Paralleling batteries

The LifeBatt pack wth the supporting plastic scaffolding ("Lego") had a great improvement on paralleling batteries. The Headway arrangement seems to be cells in parallel the joined up in series (obvious) Another obvious possibility is cells in series then the 2 (or more) strings paralleled up - thi...

Anyone had experience with this?

If it was clearly marked that the motor power was rated at no more than 200W it would most likely be able to be driven without being registered as is the case with any other e-bike with motor power no more than 200W. With the much more powerful motor it would definitely need to be registered to be a...

Ok this is not EV related but it is motor related... Looking at adding an electric supercharger to my bike to give it a bit more punch, problem is I don’t know if the battery has enough grunt to handle the current draw.

Do you think that lithium batteries are going to be same price as today in 3 -4 years? Maintenance for lithium is not resolved.

The more I read (here and elsewhere) the more I am thinking that Li based batteries won't be truly viable until they are sold pre-packaged in blocks (24V, 36V etc) that are complete with BMS built in, two terminals for traction power and some connection (eg. CAN bus) for BMS. and all this at a pric...

In 3-4 years when time will come to replace your batte4ries then you can consider Lithium-- by that time the price will crash and they will be maintenance free the chargers will become more reliable, also you may not need BMS. cheers How do you figure the price of lithium will crash?
