BMS test

Posted 03-08-2013 at 08:46 AM by sabahtom

Motor is in, main cables are crimped. Now testing BMS.

BMS is HiPower OEM. So far it powers up but doesn't collect data, only beeps at me and says theres no connection from the main data module to the data collection modules.

Etiquette In Charge

It's applaudable to see so many plug-in vehicles on the roads... but at the public charge; it's a shock. Here's a scenario philisophis electricus:

You are beyond the range of no return... You pull into your strategic public charger to find it occupied by, let's say a Volt. You can not get home, the Volt of course, can. Do you unplug it?

Comments please...

Is an AC motor in your future?

All major car makers use AC propulsion systems for a reason.
That reason is simplicity, robustness and excellent, programmable
operating parameters.

For the past year, there has been a group of people studying
AC propulsion systems. They all eventually noticed the huge
gap in the AC motor offerings from the many motor manufacturers.

The present AC50 and soon to be AC75 systems are at the top of
the "lower" cost systems...

Real needs in an EV transmission

Posted 11-01-2012 at 02:31 AM by mizlplix

What do we really need out of our EV automatic? We want it to drive like a normal car while getting GREAT mileage.....LOL

There are many commonalities with an ICE transmission as it is doing the same job and it can not tell what is turning it. The huge benefit to electricity is that at stop lights, it can sit and not use any energy. It does not need to "idle".

We can use a torque converter or not, but the automatic transmission does have one problem....

Motor in

Posted 10-22-2012 at 12:20 AM by sabahtom

Bought most of the bits for the conversion in December 2010. They shipped in and I took delivery in May 2011.

July 2012: Embarrassing mess. Wasted $$ in battery connectors made of tinned steel and copper mesh. Good lesson: make sure I post online any questions at least a week before I have to make a decision.

Eventually bought good ones and a vacuum pump for the brakes from

www.evworks.com.au/

The good ones cost 25% of what I paid for the bad...
