Antiscab:- your ECU left today. one problem though, my wife took it to the ost shop, they told her to value it at $250 for insurance purposes, it may be enough to attract customs charges?

Antiscab's NWH10 Prius plugin Lithium conversion

After working on packs maybe 50+ times I have come to the conclusion that the NHW10 pack has a major problem, like you say, because the air flow is through the height of the pack, i.e. through 7 strings and the top cells get the air that has been heated by the lower cells. the bottom row of strings ...

yes, basically senses total pack voltage (seems to stop pack discharge at 240V), any cell below 1V and keeps track of the state of charge from the current in/out. I think it may also stop charging at about 380V, but that will only happen on a equalization charge initiated from the scanner

How many bad cells will a car have? Actually, often there will be none that will stop you driving it. It depends on how the pack has been treated. If, when a battery is failing, the car is driven into the ground most of the cells can be leaking electrolyte. What happens is this; 1) car starts having...

Antiscab's NWH10 Prius plugin Lithium conversion

Hi Terry,    What you do is flatten all the old cells one cell at a time, discharge at maybe 5A until the cell voltage is o.8V, then disconnect the load and do the next. The cells should recover to above 1.1V after standing for a few hours. Any cells that are below 1.1V to start with are probably su...

Rennacs website has a facility to enter a code manually and find out what it means. I did try to find it there for you but could not get it to work. maybe phone Glen at RRennacs, he will be able to tell you I think.

Antiscab's NWH10 Prius plugin Lithium conversion

some things here don't make sense to me. I would have said that some fault codes can be cleared by disconnecting the 12V battery, but if you get a triagle then it can't. I thought the uniform charge request happened and this set the triangle.
Can you not reset the ECU from the scanner?

my thinking with the clutch is this: 1) at low speed MG1 drives power split device, clutch is enguaged, so other side of PSD (where engine would be normally) is held stationary, MG1 can drive. 2) as speed increases MG1 RPM reaches max, it then can't add torque past this RPM, so it stops. clutch free...

Rewinding Toyota Prius MG2 stator

the NHW10 uses "field weakening" to get to higher RPM than base RPM, it does this by using buried magnets in the rotor and FOC. One component of the current fights off the PM field, increasing the RPM per Volt rating. not sure what the base RPM is, and the only way I can see to use this is to used a...

"While the engine is running, the car will still discharge the battery at 10-15A continuous, when SOC is set very high. I'm not sure if running this way is particularly efficient - I'm not sure how to measure this" At times the engine is just turning over with no petrol supplied, I think that is wha...

one warning about the autospeed article - it says the connections to the engine ECU is the same as the NHW11, I don't think that's right. you can trace it from the temp thermistor, connector between engine and inverter (green and black wires)

testing has revealed a few more things: I seem to be able to update the SOC in the car only once every few minutes - not sure if the limitation is in the car or the TECU software I wasn't able to do a full drive with discharging the battery constantly as the car faulted out tonight - it has develop...

It is I think. the display only shows 25% (orange), 50%, 75% and full, and these do not correspond to the real SOC of the battery.

that's interesting, are you sure that 127 is all the car ECU can accept? how did you prove this? I know you never see below about 20% on the scanner too.

It should be possible to make a device that sets the SOC in any way you like. It seems like a simple thing to do.

my plan was to make a device on the computer bus that resets the state of charge to 100% continuously. I can do that with the cheap russian scanner, so if I can capture the codes it sends I can program a Aurdiuno or a PIC to do this.
