Lexus CT 200h

With the help of user alexve of Hybrid Synergy Forum, Torque Log Analyzer has been successfully tested against a Lexus CT 200h

OBD adapters database

While testing Torque Log Analyzer with several different configurations, I've come across some different ODB adapters.
Here are some info about each one of them.
Since online vendors often change suppliers and links become outdated, I'm just posting photos of the adapters, so they can be searched online at the best price.


1)

No problems reported: collects as many as 45 PID/sec with no missing data.
ELM327 version: 1.5
Bluetooth pairing: needs pairing every new trip

2)

Duplicate rows on collected data, some PID reported as 0 from time to time.
ELM327 version: unknown
Bluetooth pairing: unknown

3)

No problems reported
ELM327 version: unknown

Bluetooth pairing: unknown

4)

Duplicate rows on collected data, some PID reported as 0 from time to time.

5)

Disconnections reported
ELM327 version: 2.1
Bluetooth pairing: persistent

6)

80 PIDs/s

• SOC drifting detection has been added
• sheet size has been corrected for all chart sizes; now zoom on charts should be more usable

SOC Drifting

While searching for methods to evaluate HV Battery fitness, I've found this thread on the Hybrid Synergy Forum:

State of charge is primarily calculated using coulomb counting and is dynamically corrected using SOC drift points. 
Coulomb counting is a method that keeps track of current going into and out of the battery pack. Coulomb counting generally works quite well as long as the capacity of the battery is known and the current sensor is accurate enough. 
Because no coulomb counting system can be perfectly accurate, errors will eventually build up. 
To correct those errors, dynamic state-of-charge drift is used to compensate.

It seems that from time to time, SOC may vary by several % points with no significant currents applied.
Those variations may indicate a less-than-ideal battery condition.

Drifting detection has been added to Torque Log Analyzer: whenever such unexpected variations are detected, they'll be reported in the Analysis sheet.
If drifting is reported, a full HV Battery Fitness check is advised.
