Hybrid batteries are quite small even if they have 90 km range. This means that a good burst of acceleration can lower its voltage, and even more if it's already close to depleted. So whenever the battery is close to being depleted, it can show as depleted depending on how big a charge draw you require from it.
The hybrid battery recharges itself from normal use of the car, so it's normal to have a higher charge than when the battery turned off. My guess is once it's marked as depleted, it won't allow use again until the percentage comes back up and it's connected to charge.

This is one of the main problems with hybrid cars that have 100 km range from the battery. The battery tends to be used too much as the car is run in EV mode for 85% of the usage time. Sadly, I've seen several friends'/family's hybrid cars with failed batteries during the warranty period due to this. It gets replaced but you tend to be afraid of using it or want to get rid of it.

From my point of view hybrid cars should only be used in EV mode below 50-60km/h (in cities mainly).
Also, is it really bad to use the battery over 60km/h cause I ve been doing it for a while now.
