Battery Suppliers

Post by 4Springs » Mon, 07 Aug 2017, 19:26

The AEVA Launceston Conversions Group are helping out Launceston College to convert a Mighty Boy to electric.
The vehicle is purchased, with parts all over the floor.
We have a motor, controller, and lots of other bits. No photos unfortunately, must get onto that...

We need to make a decision on what battery to use. This is where we need your help!
What batteries are available now? This is a small vehicle, so we're looking for something small and light. My guess off the top of my head is that we'd be looking for about 10kWh - it doesn't need to travel far in its' job as a school project.
My thought is something like used Leaf or Tesla cells. Price is a consideration but may not be too difficult if we can get a sponsor. Would be great to get something that means fewer connections. There is some haste on this project so an Australian supplier would be preferred.

If you know of suppliers please post them here. If we get lots of replies then hopefully this will be a useful thread for others as well.

You need to tell us the nominal voltage of this battery, so we can work out amp-hours and number of cells in series for different chemistries.

Why not start with a lead sled?
Cheap and available at your corner store.
It's likely they will kill something in the beginning anyway.
Then in following years the next lot of students can upgrade to lithium when more funding is available.

We have a controller that has a range of 92 - 170VDC and 600A. I guess about 150V would be best, since that is fairly common.
At the moment we can only afford about 160kg of battery, so lead won't go far. And there seems to be a willingness to find the money for lithium.

So about 20 Leaf cells is about 9kWh 152V.
There was someone around that had something like that qty from a wrecked leaf otherwise check with SuziAuto what the availability is like from the US.
The Tesla cells - not too sure if anyone has had success (yet) getting module in ebay or otherwise.
In my opinion the Tesla modules may be harder to work with than the Leaf cells for a student project.
