The national standard xc3 electric car App keeps showing 100%. What's the matter?

1, the battery is dead, the battery is aging, or the display panel of the electric vehicle is broken, so it always shows full charge. It is recommended to go directly to the repair shop for inspection and maintenance.

2. It is the phenomenon of battery self-discharge. At this time, although the dashboard shows full power, it is actually only virtual power, and the real power is only 70% or even lower.
