Firmware

Corrections de bugs et mises à jour de sécurité

• Cette version sera disponible pour installation via certains concessionnaires Zero Motorcycles dès maintenant.
• Cette version sera disponible pour une installation à distance (over-the-air) le 17 juin 2026.

• Fix: Resolved a bug where in certain conditions, the displayed SoC did not match the actual charge level, resulting in the bike running out of power before the gauge displayed 0%.
• Note: On bikes where this issue was present, the range estimate and battery percentage may appear lower after this update. Actual riding range is not affected.

• New: Power management of main power pack optimized for transport and seasonal storage.
• Fix: Transitioning logic to limp state is now more predictable.
• Fix: Refined BMU voltage measurements to prevent false fault triggering.
• Fix: Odometer format refined to follow international diagnostic standards.
• Fix: Refined BMM initialization of critical settings during startup.  

• Fix: Resolved behavior that would cause a false Isolation fault during charging
• Fix: Resolved behavior that would block the ability to commission the motor with DIAG4Zero after replacing the motor controller.

• Enhanced key switch fault detection and handling Improved vehicle behavior when key switch input is lost during operation Added safety interlocks for OTA updates Maintained lighting and MBB operation during key switch faults

• This release includes minor bug fixes and optimizations to improve overall user experience.

• Resolved a bug causing SoC to drop shortly after a completed charge event.
• Improved range estimation algorithm when traveling downhill.
• Fixed a logging bug around reported charger temperature

• Added support for new Australia variant motorcycles.
• Resolved an issue causing false positive battery fault on startup.

New Features:

• When the power pack gets to 0%, the motorcycle will no longer periodically wake to run system checks while keyed off. This periodic wake state will only re-enable once the motorcycle is charged.
• Support for 3kW charger updates.
