BMS Cells Stats

The Cells Stats sheet of the BMS analysis reports some fitness measures for each of the battery cells:

• Avg Bias: average of how much the cell value differs from the average of all other cells value.
• Max Bias: maximum difference from the average value observed for the cell
• Lowest Value: the absolute minimum reached by the cell
• Std Dev: standard deviation of cell values, measure variability of values

Minimum and maximum values are highlighted so best and worst cells can be easily spotted.

MD-Tech BMS

Torque Log Analyzer now understands logs from the Prius 2 PHEV kit from MD-Tech.
Note that the kit saves files with a .XLS extension, but they really are just text files, so rename them to .txt before importing.

A correctly imported file should look like this:

Be sure to select BMS MD-TECH in the options before clicking on Analyze

Two charts will be produced:
One for cell values

One for SOC value

The Analysis sheet will contain cells details:

Activating Torque Log Analyzer as a Google Sheets Add-on

After installing Torque Log Analyzer, you'll have it ready in all your Sheets: it just needs to be activated.
When you open a new sheet, you'll find that the Torque Log Analyzer menu contains only an "Help" item:

To enable it, select "Manage add-ons"

Then select "Manage"

Now select "Use in this document"

and "Reload" the whole sheet.

The add-on will be enabled and available.

• EV Behaviour
• Driving Errors
• EV Excess and Short Ignition charts were removed as they are now part of the Driving Error chart
• Analysis sheet is always activated as last step
• added labels to all sidebar checkboxes and widgets
• options are now shown in alphabetic order in the sidebar
• charts are now sorted alphabetically

The Driving Errors Chart

The Driving Errors chart provides an overview of common engine management errors.

Car speed is drawn so you can have a reference about your trip.

• EV Excess: EV usage is considered excessive if you're using more than 30A for 5 consecutive seconds with SOC < 60. Try to avoid it.
• Short Ignition: the petrol engine was ignited for less than 5 seconds. This is considered wasteful.

The EV Behaviour Chart

The EV Behaviour chart provides an overview of your EV driving skills.

Car speed is drawn so you can have a reference about your trip.

HV battery State of Charge is also displayed. Keep in mind that 60 is the level the car wants to achieve.

On the lower section of the chart you can find the notable states of the car as follows:

• Car State EV: car is running with the EV indicator lighted up.
• Car State Gliding: car is in EV and running with 0 battery consumption and no fuel either.
• Car State EV Regen: car is in EV and charging the battery from coasting or braking. Note that this is different from generic regenerative braking, as that may happen even when not in EV.
• Car State EV Traction: car is in EV and using current from the battery to power the electric engine. Try to use this as low as possible.
• EV Excess: EV usage is considered excessive if you're using more than 30A for 5 consecutive seconds with SOC < 60. Try to avoid it.

The EV Behaviour Map shows the same info above a map of the road so you can easily pinpoint parts of the trip.
