The MBB has an event log which an owner can access.

The BMS on each installed battery also has an event log that can be emitted, but takes longer to access.

The logs are encoded in a custom binary format with a header and a number of event entries.

Messages are often embedded within the file in addition to numeric measurements referred to as conditions.

Reading the logs involves using a parser.

Zero provides log parsing as a service to dealers and owners when you send them logs, but the community has developed parsers for roadside assistance or help when Zero is not cooperative.

Access

• See the Official Mobile Application for instructions on how to do this normally.
• See MBB Console for direct interactive access.

Mobile

• On Android, logs which have been produced by the Zero Motorcycles application can be found in Android/data/com.ZeroMotorcycles/files/ and are named with the VIN, the source (MBB or BMS), the timestamp, and end in .bin, whether or not they actually emailed correctly.

Format

The logs are encoded in a custom binary format with a header and a number of event entries.

Messages are often embedded within the file in addition to numeric measurements referred to as conditions.

The format has been reverse engineered into a relatively well-documented format here: https://github.com/zero-motorcycle-community/zero-log-parser/blob/master/log_structure.md

Interpretation

• The files can be interpreted via the code at https://github.com/zero-motorcycle-community or the web interface at http://home.hasslers.net/zerologparser/
