Do I need a new controller?

Thanks guys, The problem with my understanding is that over the last 7 years I have fiddled around with wiring in the car. Bear in mind the "I" in the sentence above knows nothing about electrical wiring. The chances of me NOT having touched the TRAC pack, and body of the car, simultaneously, at lea...

Do I need a new controller?

Thanks tons for your help John! I do use a 5:1 voltage prescaler. Their reply causes two questions in my tiny brain: a) I get 39v even if the shunt wires are disconnected, whereas their reply appears (?) to imply that the short can only happen through the shunt wires? b) How come it worked fine for ...

I think I have a manual for the TBS Pro somewhere so I will have a hunt around for it Johny. I have a very busy day today so I don't think I will be able to get back to you on this until tomorrow.

Thanks

Do I need a new controller?

Hi people, Progress! After my holidays and my brother's holidays we finally got together yesterday. We followed Richo and Johny's instructions and still ended up with 38 to 39 volts between the traction pack and the body of the car. We disconnected all the components connected to the Traction POS th...

Charge Station locations

To have 20 stations in one spot is good as it should reduce the chances of being ICE'd. Unfortunately I couldn't see any restrictive signage like "Electric Charging Station Only - No Parking".

The end result could be that they end up with 20 non EV's taking up those spaces! Extremely annoying!

Hopefully I can then tee up a day for us to work through your instructions. I still have the heater we o...

Do I need a new controller?

I went through every cell terminal and connected each to the neg side of the aux battery. When I eventually got to the last pos terminal of the entire bank I got a zero reading. The last neg terminal, when connected to the chassis, gave me a reading of -120v. I assume from Richo's comment my short m...

Do I need a new controller?

Thanks Richo, I will have my gloves on! When you say to each traction battery terminal do you mean to each positive and negative traction battery terminal? If to both the positive and negative terminals do I, when testing a negative traction terminal, put the other end on the positive of the aux bat...

Do I need a new controller?

Thanks Evric,

When the car was at the workshop I actually used the fact that it was up on a hoist to do exactly what you suggest! I had heard about carbon dust build up and took the opportunity to use their compressed air gun. One of the rare instances of me doing something sensible!

Thanks

Do I need a new controller?

Thanks Johny,

When I say the rear pack was disconnected I mean that I had depressed my big red button between the seats inside the car. I had made no other "disconnects" between front and back.

Thanks Johny, Richo and Peter, We will try your suggestions. Richo, to answer your question as to how I know the HV is connected to the body is that one of us was leaning on the compliance plate of the car (connected to the body) and touched a terminal and got zapped. I had disconnected the rear bat...

Charge Station locations

Apart from Plugshare there is of course the ChargePoint map. If you mean, is there a section on this forum, you will find the NSW locations mentioned under the Sydney Branch of AEVA in the Branches section of this forum.

We discussed, in a separate thread, the ways to improve charging stations and agreed that their usefulness is largely dependent on: a) Wh...

Thanks to 4Springs, Adverse Affects and poprock!

I think I am getting the hang of it! Though trying to get any concept into my head is like trying to chip away at a brick wall with a spoon!

Which gear gives lowest amp draw?

Thanks Johny and Richo,

I assume Richo that the figures, ranging from 77+ to 92+, on the graph you supplied, are percentages? ie 77% to 92% efficiency?

Thanks again,

Which gear gives lowest amp draw?

Hi people, I have received advice from a number of sources recently that electric motors are more efficient at higher rpms than at low rpms. I assume that the term "more efficient" means that motors draw less amps at higher rpms than at low rpms. If I can draw less amps then I can increase my range?...

Thanks tons Peter and Johny, At the moment I am running at a battery voltage of 113v max (about 109v nominal). The 96v controller has once gone into thermal cutback and I was therefore worried that adding two more cells to take me to 115-116v nominal may overload the controller on a hot day. I have ...
