SOC Gauge update

Some of you have been asking about the SOC gauge.

The plan:
The estimated cost is going to be near the $200 mark. Maybe $175.
It's going to have several more features other than just the SOC gauge. Mostly convenience features. (clear the "I agree", possibly a "charge to n %" feature, etc)
It will sit in the most forward area of the center console (behind the cup holder)

The problem is that there just isn't a market for it to make it profitable. Sure there are some people interested in here, but we are talking about $10k in engineering costs (time and material). I'd have to sell one to 30% of the people on the spreadsheet just to break even. I just don't think there are that many people interested.

So I'm thinking of taking preorders just to see how many people are interested. I wouldn't charge your card until it shipped.


I also may look to license the information out to someone that can do something with it. I heard Autogauge might come out with something. It won't have the other features I was planning on offering, but they can bring something to market much cheaper than I can because for them it's just a firmware update..

Thoughts welcome.

The time window for the value of your CAN information is limited, perhaps 3 months to a year at most, before the other CAN-decoding efforts release the same (or similar) information into the public domain (or via Open License or some such).

If you cannot actually make some money on your decoding discoveries soon, consider using it here to help and advance the other efforts. Others here can probably make a CAN-JACK micro-processor and display very easily, and we might all benefit.

Apparently they have logged (recorded), with milli-second time stamps, all the messages from all 3 CAN busses, for many hours, full charging sessions, etc.

I would absolutely pre-order one. ESPECIALLY if it got rid of "I agree."

I'm on the "definitely would buy" list and would happily preorder! I'd pay extra for the convenience features that you outlined...

1 month of the money I would have spent on Gasoline to help someone with the effort and get a cool gadget to boot,yep and natch! Count me in for 2 Cs.

Of course, assuming Nissan let's me even order the car in July...

I am very interested if it does all 3 of the things you mentioned.
If it is just an SOC gauge, then I could live with the "bars".
Have you got the "I agree" bypass and "charge to n%" working already in your prototype?

if you are taking requests, i would like some sort of gauge of "charge in" with L1, i can use Kill a watt, but suffer from a minimal 10% decrease in charger efficiency. using L2 will get me better efficiency but then i lose the ability to track how much power is coming from the wall.
