Griswald. I took a look at the Ultragauge and wondering what the: Brake Horsepower & Brake Kilowatts sensor information gives. I have the ScanGauge2 and really don't think much to it really. Trying to figure out what the sensor combinations are is frustrating. I was looking to try and get a sensor that tells me not only the engine RPM, but wanting to know how much charge you get from the regenerative breaking.
Also, the cable that comes with the Scangauge doesn't allow you to install it on the OBDII port and still fit the front plastic cover back onto the dash. I am wondering if the Ultragauge plug is thin enough to do this? I am driving a standard HEV Kia Niro EX, not a plugin so I don't know if the panels are different between the models.
There almost certainly will be a PID for charging voltage in the BMS, perhaps one that specifically shows the regen. OBD2 has expanded tremendously since its introduction. There are many standard PIDs for EVs, and even PIDs specific to a manufacturer. There are lots of PIDs online for the Kia Niro, Hyundai Ioniq (exact same ones) for HEV and BEV variants. Should be the same for PHEVs.
There is a lot of good data available, but I haven't set up mine yet with some of the interesting hybrid related PIDs. I'll get around to it some day.
Assign? That would only apply to the very limited wired version with a dedicated display. Otherwise, you can output unlimited gauges on a smartphone. Generally apps come pre-formatted with gauges the "average person" who buys an OBD reader will care about, but none come formatted with gauges aimed at hybrid/EV owners. Those super average users can format the gauges they want to see, and delete those they don't care about.My point was that while the information may be in some kind of PID format, I really doubt that a company like Ultragauge would be willing to assign one of their screens to it for the average consumer to view. Yes, that info might be available, but certainly not something that the average person really cares to know.
The reason for wanting that information is the Niro is a hybrid. All hybrid cars have regenerative breaking and power generation from the ICE. Us propeller heads that look towards trying to get the most economy out of our vehicles would want to get the most power out of these regenerative methods as we get free distance so to speak from running in EV mode vs if we were just running on an ICE alone. For example, when you are driving and you take your foot totally off the accelerator, the dial on your dash flicks down to regeneration. You'd want to know how much power is actually getting into that battery. I know from the Prius forums that with your feet off the accelerator but not on the break, just a small trickle of power is getting into the traction battery. But if you press a bit on the break, but not enough to really slow down the car, the small trickle jumps up to a pretty good flow of power. So a trick when driving is to look far enough ahead to what is happening and press lightly the brake pedal early when you see the traffic light coming up is red. Yes, you could wait and press the break much later but then you are using not only the regenerative motor to put power back into the battery but also the disc breaks that give you no power back at all. The difference can add up to a half MPG over a trip. Then you can also look into when the ICE is running and you are putting some of that power towards charging the battery and the other to drive you forward. Generally, that is accelerating, but if you knew the %each way you might decide that a little less acceleration might make quite a difference towards how much power is added back into your traction battery. Again, saving you some more MPG. To say that this information is not wanted to be known by anyone is nieve. Anyone who is a hypermiler and wants to get the most distance to each tank of gas, what is going on in the battery system is of great importance and interest.
The two tag values were from the Ultragauge web site, so they are already in their system. What I don't have is a really good description of what they do, nor an Ultragauge to try it out myself. I was hoping that someone who has the gauge and happens to be driving a Niro could give it a test to see what data it gives and see if that info correlates with what it sounds like the tags are named. This might be useful info.
