All: Having obtained some Clarity PID's, and getting set up with Car Scanner, here is an example of something very cool that we can now do: (see this thread for more of the how: https://www.insideevsforum.com/community/index.php?threads/budget-battery-capacity-readout.10531/) Many have been interested in the nature of the Regen and the use of friction brakes. There is a parameter that can answer this question once and for all !! Among the wealth of OBD2 parameters, there is the brake pressure. This is a sensor in the hydraulic system that can truly indicate when friction brakes are actually being applied. There is also a brake switch which indicates exactly when you just begin to touch the brake pedal. This, coupled with vehicle speed and the HV battery current (indicative of when regen is occurring) can make for some very interesting displays... I recorded these parameters during a drive yesterday. This example is just scratching the surface of what we can do with this new-found instrumentation... I am going to show you two examples. First, a "normal" stop from 55 mph to zero in around 25 seconds. This was approaching a light that we knew was red from a long distance away... At around 520 seconds, our speed begins to drop. The brakes are applied (red curve - look at the flat value of 10, ignoring the spikes). The Regen kicks in (-50 amps, secondary axis). The car reaches virtually 0 mph before the brake pressure shows application of friction brakes. The friction brakes are only engaged in this case while the vehicle is stopped and we are waiting for the light to turn green. Now - Here is a "Panic Stop" where the light changed unexpectedly and we stopped very quickly (this time from about 35 mph to zero in about 5 seconds... In this case, the brakes are applied (red, ignore the spikes). The friction brakes kick on immediately up to 20 bars (~300 psi). Regen is also applied (-40 amps). After we are stopped, the brake pressure again goes up to 10 bars just to hold the vehicle while waiting for a green light again. These parameters were recorded using Car Scanner, and exporting a .csv file for plotting in a spreadsheet. During the drive, all this was visible real-time on a 'dashboard' within Car Scanner. Note, on our drive, I saw HV Battery current that ranged from -120 Amps (very high regen) to +200 Amps (high acceleration). The first 4 ticks on the dash display corresponded to 30, 60, 120, and 200 Amps.
