regenerative breaking with a dc motor setup

yes and no. you could use a VFD and induction motor. This would give you the most control, however this would render the DC setup redundant. You could buy a sepex motor and use a second controller to run the field windings, but if you went this route, you may aswell just use a sepex traction motor. ...

you could try www.batteryspace.com in the mean time, you could use a 30v lab power supply, and set a max voltage limit of 19v (assuming 5 cells in series), and set max current to what ever the standard BMS was designed for. what BMS are you using? are you using the stock one that came with the dewal...

making AC current?

if you want AC, have a look at www.metricmind.com and www.electroautomotive.com pretty much if you have to ask if you need a special conrtol, i wouldn't suggest trying to build your own. Though the systems from both those sites are already engineered and arent overly easy to modify. nor are they che...

Thinking of converting a Toyota Hilux

i would go for the zilla 2k aswell, itll give you much better acceleration anyway (assumign your batteries can handle it, optimas and most AGM lead acids can). Altough it is a little pricey, about $6k by the time you get it over here. After having a chat with my favourite customs officer, you need t...

Thinking of converting a Toyota Hilux

if your going to use an 11", use a strong controller such as a zilla 1k or a dcp raptor 1200 or stronger and ditch the gear box. If you want to retain the gearbox, you may aswell go for a smaller motor, and weaker controller. If you push 1000A or more through either 11" you run the risk of destroyin...

Gday Mike,

do you have a blog or web page for your conversion?
an aw11 is my ideal conversion vehicle, so i was wondering if you could tell me a few things.
how heavy is the engine and related components you are able to take out?
how heavy is the chasis and body with no engine?

cheers,
Matt

an optima set would set u back about $4000, increase weight by 350kg (50% at least), and increase power by 150%, decrease range to about 50km.

If you make more than 4 units a year than the whole thing has to go through dotars, which is spectacularly expensive. If you were going to manufacture evs, start with a vehicle thats already been through dotars. As for a one off, a 9" warp ($2400) + 1k ehv zilla ($3000) + 90xlfp40aha ($12000)+charge...

sounds good.
I own two 12.8v 20AH Yesa packs which look similar to the ones shown on the site. Ive put about 2000km on them, and theyre holding up well. I'll have some cycle data on them when i get around to putting a paktrakr on.

I'd be interested to hear the quoted prices, especially in quantity

The really expensive AC EV conversion kits are lighter weight and smaller than the standard industrial VFD's budget conversions use. There are a few names for the motor controller, VFD and inverter. All do the same thing, convert a DC bus voltage (usually around 600vdc for greatest effectiveness) to...

Hi ckas, ive owned 2 emaxs (the scooters emc have). The silicon batteries are rather stiff voltage wise, ( will maintain 12.6v at 3.5C or 70A) when fully charged.
