Trip history log
The trip history log can be used as a source for long term statistics on your trips and typical trip power usages, as well as your battery performance in different environmental conditions and degradation over time.
Entries are created at the end of a trip and on each change in the charge state, so you can also see where charges stopped or how long they took and how high the temperatures got.

Extended GPS log
The extended GPS log contains additional details about power and current levels, the BMS power limits and the automatic power level adjustments done by the OVMS. You can use this to create detailed trip power charts and to verify your auto power adjust settings.
The log frequency is once per minute while parking/charging, and controlled by config xrt
gpslogint
(web UI: Twizy → Features) while driving. Logging only occurs if logged metrics have
changed.

Battery pack/cell monitoring log
The extended GPS log contains additional details about power and current levels, the BMS power limits and the automatic power level adjustments done by the OVMS. You can use this to create detailed trip power charts and to verify your auto power adjust settings.
The standard log frequency is once per minute, logging only occurs if logged metrics have changed.
Additional records are created on battery alert events. Note: an entry consists of a pack level
record (RT-BAT-P
) and up to 16 (for LiFePO4 batteries) cell entries (RT-BAT-C
).

Power statistics
The power statistics are the base for the trip reports and can be used to analyze trip sections regarding speed and altitude changes and their respective effects on power usage. The log is also written when charging, that data can be used to log changes in the charge current, for example triggered externally by some solar charge controller.
Log frequency is once per minute, logging only occurs if metrics have changed.

OBD2 cluster DTC log
This server table stores DTC occurrences for one week. This is mostly raw data, and the DTCs are internal Renault values that have not yet been decoded.

SEVCON faults & events
These logs are created on request only, e.g. by the SEVCON logs tool in the Android App, or by
using the xrt cfg querylogs
command. The command queries the SEVCON (inverter) alerts, faults,
events and statistics (SEVCON needs to be online). The results are then transmitted to the server
using the following records.

xrt.sevcon.log

SEVCON live monitoring
These records store the measurement results of the virtual dyno included in the SEVCON live monitor (Twizy → SEVCON Monitor). The virtual dyno records a torque/power profile from the actual car performance during driving. The profile has four data sets:
Maximum battery drive power over speed (metric
xrt.s.b.pwr.drv
, unit kW)Maximum battery recuperation power over speed (metric
xrt.s.b.pwr.rec
, unit kW)Maximum motor drive torque over speed (metric
xrt.s.m.trq.drv
, unit Nm)Maximum motor recuperation torque over speed (metric
xrt.s.m.trq.rec
, unit Nm)
Power is measured at the battery, so you can derive the efficiency. Speed is truncated to integer, the value arrays take up to 120 entries (0 … 119 kph).
These datasets are visualized by the web UI using a chart, and transmitted to the server on any monitoring “stop” or “reset” command in the following records:
Notification subtype:
xrt.power.dyno
