How to convert a hybrid

Indeed, it was not meant to be only for NHW10's that would continue with a "Power Jockey", but for NHW10's so that they will get rid of the dangerous "Power Jockey". Oops! I left out the important fact that this is for NHW10 hybrids only; I've added that to the post. Thanks for pointing that out. I ...

How to convert a hybrid

My understanding is that this is for NHW10 owners in NZ who have a "Power Jockey" installed. At least that seems to be how it started.

I haven't looked into the details of that. However, it does seem that the Rennacs can do what I would want. It also means that a DIY solution is possible, perhaps using say the Silcon Chip OBD2 scanner as a guide. http://www.rennacs.com/ http://www.siliconchip.com.au/cms/A_111859/article.html I hav...

testing kwh meters

The cheap meters have big problems reading the power consumption of devices with a low PF - do I understand that correctly? If yes, then I have a question: Will an el-cheapo meter measure the power consumption of a given device with low PF with the same error factor each time? Or will the results be...

Thanks for your comments, T2, and welcome to the forum! Could it be you missed that we are talking (among other things) about a NHW10 Prius? The main difference to the later NHW11 etc models is the battery. It has 40 modules of 6 cylindrical cells, making a 240s NiMH battery. The main design fault i...

The Prius MK1 is running again!
Just need to wait for the silicone to dry on an indicator repair job, and get new windscreen wipers, and it should get a Safety Certificate without problems.

It's the blue one, sold for 2125.- few days ago. I had a look at it before bidding, found cooling impellers and BMS and a heap of screws in the boot.

I have a 20km commute with half of it at 80+ km/h. Some parts of it ar uphill at 80+km/h, that will be a problem for pure EV mode; but a lot of the downhill parts could be done with the ICE off.

big batteries and step up DC converters

Is it physically impossible to convert 3.5V DC to DC of (several)hundred V? Or is it just not possible with the components available today? Or is there some physical law that makes this impossible without severe losses? The heavy conductor (required to carry very high currents) is not an issue IMHO....

Home grown BMS ideas !

Is there any problem at all with the odd cell having an increased self discharge rate (with LiFePO4 cells)?

With NiMH cells the weaker cells often self discharge faster than the others; therefore the top-balancing is needed to stop a differential SOC developing.
