Hi. Bought new 2019 Prius. At a good deal.or was it ? 3 weeks, my battery on Display varies from 7 Bars then 3 Bars. Up & Down. Is this normal ? I thot a Battery stayed mostly up to 90% mostly. Making just short trips. Thanks.
The battery display is the charge level indicator. As you drive, the system uses the electric motor along with the gas engine. The battery charge changes with electric motor use. When you brake or coast, part of your braking energy is returned to the battery. So the changing levels show the hybrid system is working.
