Davide is an experienced Android developer, with a long list of released apps.
Check his page at @Appsbydavidev.dev or at http://dev.appsbydavidev.it/
The new version of Hybrid Assistant already features his contributions:
- crash dump reporting: if an error occours, HA will ask for permission to send a dump to the developers
- new settings menu
- new settings page
- multilanguage translation (English, Italian, French, German, Spanish)
Other minor enhancements include:
- accelerator position is now displayed
- accelerator color is based on CHG/ECO/POWER meter
- fix for false readings on Prius Prime
- support for Toyota Highlander
- better detection of ICE spinning

LGP tweaking

A creative user from Hybrid Synergy Forum has found a way to use Hybrid Assistant for checking an LGP modified engine that was behaving erratically.
Using the fuel trim chart he helped the tech support to correct settings of the engine LGP control unit.

Full story is available here:

By his suggestion, the new version of Hybrid Reporter now charts fuel trim corrections for each RPM range of the engine.

Here is the map of the misbehaving engine, with very high trims at high RPMs

After tweaking, the trims are back to lower values

LGP fuel quality evaluation

Joshue Martín de Blas, a long time friend of Hybrid Assistant, has put to good use the Fuel Trim charts of Hybrid Reporter.
In his own words:

These 2 Fuel trims graphics are of the same trip, but with different LPG brand. It's clear that in one case the effective Fuel Trim is bigger (and the fuel consumption higher also), because the ECU needs to make much more corrections tho the injection time.

HV Battery Capacity Estimate

During an HV Check, an estimate of the battery capacity is also shown on screen.
All models (except Prius Plus and Prius Plugin) have a nominal 6.5 Ah battery capacity.
To evaluate capacity follow these guidelines:
1) be sure to have at least 60% SOC, engine and battery at operating temperatures (i.e. not too low or too high)
2) park the car
3) start A/C at the lowest temperature, to put some load on the battery
4) be sure the petrol engine is not running and have completed S1 phase
4) start HV Check
5) keep the check running until actual SOC is at least 10% less than the starting SOC

The Estimated Capacity will change color when enough data will be collected.

The same information is present on the report from Hybrid Reporter


New Release

HA:
  • Capacity estimate in HV Check
  • Fix for trip data missing during HV Check
  • Changed SOC red color at 42% 

HR:
  • Fuel chart with km breakdown

Fuel usage over distance

The Fuel usage over distance chart plots consumption on a distance scale.
The green line shows overall fuel usage starting from the beginning of the trip, while the red histogram depicts local fuel consumptionin every single kilometer of the trip

Voltage Delta Chart

The Voltage Delta chart plots voltage differences between blocks.
The bottom area plots delta value between maximum and minimum values.
Min, Max and average values are also plotted.
If the average value is not roughly halfway between min and max, we may have a block balancing issue.

HV Battery Temperature Chart

The HV Battery Temperature chart plots temperature sensors values during an HV Check.
Common thresholds (fan and EV disable) are also shown, along with current.


Block Values Chart

The Block values chart plots individual battery block voltage values.
SOC % level is also shown

Time in motion

The EV summary panel can now display trip time as total time or just time spent while the car is actually moving.
You can tap the panel to switch between the two information.

Reset

You can reset all options back to default with the "Reset All" button.
Note that this will also delete all trips data from the database used by Hybrid Reporter.
Settings will be reset as soon as you restart Hybrid Assistant.
