The power arriving to my motor is sometimes cut down from nominal 5 kW to 4 kW, then 3kW, and eventually to 0.8 kW (10A at 80V).
BUT
Battery is full (80V for a 72V nominal battery).
Cells are fine (lowest is at 3.3V, highest is 3.34V)
Temperature can vary from 15°C to 35°C when problem arises.
Motor is rated 6kW continuous, 8kW peak.
The problem sometimes happens when leaving parking: I can't cross 20 km/h; other times it happens when running at constant speed 60 km/h, which of course is cut down to 40, then 30, then 10...
How can I track down the cause?
Can I read some diagnostics from the controller while running? I see it has CANBUS enabled, but I can't get any info from the vehicle manufacturer (Zhidou Zindayang).
Is it any SW update available for this controller.
