current limiting on Curtis and TS cells

Thanks for that info. It would make sense that more chemistry will happen when it is hotter. I'll have to look forward to hooning in summer! In the dead of winter perhaps I'll have to make a point of setting the timer on the power point to finish the charging just before I want to use the car in the...

My silly battery charging idea

I think if I were to be serious about this, and I don't think I will be, I would be looking at the flexible sort of solar cells or the sort that get embedded in resin over the top of the solar challenge-type recumbant bicycles. I would think those would add the least to weight and wind resistance an...

My silly battery charging idea

Can we all join in this game? I'm just speculating idly here. I know it makes more sense to put solar panels on the roof at home than on the car, and I do have them on the roof at home. However, if I were to have some in/on the car and wanted to charge the main traction battery.... I could put some ...

current limiting on Curtis and TS cells

Now I have my car registered, I have driven it for a few more days, and the weather is getting chillier it seems the BMS alarm goes off pretty precisely at 3C (270Amps). I have the cells and BMS bits all at the rear of the car. I have the controller and everything else at the front. I would think th...

Peter Campbell's Charade

As requested some comments on the registration process: I am in the ACT where is only one other home modified EV registered that I am aware of (Sacha's Hilux). At least one other EV-Charade was on the road for a while in the early 90s however. There are 4 engineers in ACT accredited to provide repor...

DC to DC converters

If your alternator warning lamp is available - how about something like this? I had started to think (not very seriously yet) about how I might use the 'charge' lamp for this purpose. I like your circuit and will put it on my list of refinements. I like the idea of having a minimum of extra meters ...

DC to DC converters

I just learned a useful lesson. My car suddenly stopped working on the way home from getting its clean bill of health at the engineer's. It could have been embarrassing if it had happened earlier. The problem was the fuse to the DC/DC converter had blown some time earlier and the car continued runni...

Insurance

This morning I took out 'comprehensive' insurance on my Daihatsu charade conversion with NRMA. They were cheaper than others I spoke to with discounts for length of membership, no claims, good record and other policies etc.. Like all the others NRMA have trouble with a comprehensive insurance that w...

Peter Campbell's Charade

I've got the tick of approval from the engineer. With the 45 TS 90s behind the back seat, mostly in the spare wheel well, I had added weight to the rear and it was obvious that the rear was heavier and the front lighter than original. The engineer's report says the car now has a 50/50 weight distrib...

Don's Mazda 121 Conversion

Just a comment on the stands. I used the same four blue stands for my charade conversion and worked under the car. I was conscious of the slight possibility of pulling the car off the stands if I was really wrenching hard on a tight bolt in the deconstruction phase. I made a habit of keeping a coupl...

current limiting on Curtis and TS cells

Thanks for the suggestion. I'll look into the Cycle Analyst and note it for the future. For now, I can't really justify changing from the TBS meter system I have installed. I think I will just have to stick to instructions that the alarm might indicate harm and go easy on the battery. I agree that t...

current limiting on Curtis and TS cells

It was fairly chilly though not below zero for the few days I got to drive on the roads last week. So, the cells would not have been particularly warm, except to the extent I might have warmed them being lead footed. Once the car is back from the engineer I will be able to test further but my initia...

current limiting on Curtis and TS cells

Hi, While my car is off being inspected and hopefully approved by the engineer I am thinking about my first impressions of driving the car for the last few days with a permit to drive it unregistered. I have a Charade with ADC 8", Curtis 500Amp controller and 45xTS LiFePO4 90 Amp hour cells with the...

Peter Campbell's Charade

It's with the engineer now. It's like I have left my baby at the hospital! Will it be pronounced healthy (roadworthy) or will there be a bombshell? He is also going to fit some new rear springs and shock absorbers since the car is clearly down a bit at the back (3-4cm from when I started) with proba...

How to feed an original tachometer?

I guess I don't yet know in practice. On one hand I have been told I could expect to start and drive around in 3rd all the time. On the other hand I have heard the comment that one might occasionaly want to start off in 2nd with a load up a hill, or even all the time. It's not so much that you could...

How to feed an original tachometer?

It occurs to me that a useful addition to the over-reving circuit could be a buzzer. One way to over rev would be the one suggested, namely accelerator pedal while in neutral or driving in too low gear, and the circuit would work for that. Another way would be to use low gear to get up a steep hill ...

What your engineer wants to see

You can also get strap that uses a tool to tighten it. Then it isn't 'hand strap'. The type with a tool can also be steel rather than plastic and has a crimped connection. I doubt if your bulge plates would move with that stuff around them.

What your engineer wants to see

I had a first interview with an ACT engineer recently. I showed him photos on the lap top of what I had done to date. He generally seemed happy with it all. The main area I had not yet got to at that time was also the area where I had least confidence, namely, how to attach my battery restraint to t...

How to feed an original tachometer?

Great. I'll try part 1, moving the tacho pointer, and this limiter circuit later. You could probably do a roaring trade in these made up nicely in a little box.
thanks,

How to feed an original tachometer?

Ric,
Do you have any updates on your circuit?   I might try it while the paint dries on my battery box. Do you have it actually making your Barina's tacho move or is it still theoretical?
Thanks,
Peter C.
