Based on the information you provided, it appears that the "charge" light on your charger has turned off, leaving only the power light illuminated. Additionally, the three blue lights on the dashboard that indicate the charge level have gone out as well. You are wondering if this means you have a full charge for your electric vehicle (EV).
While I cannot provide real-time diagnostics or confirm the exact status of your charge, typically, when the "charge" light on the charger turns off, it indicates that the battery has reached its maximum capacity and is fully charged. However, it's essential to consult your vehicle's manual or contact the manufacturer to ensure you correctly interpret the charger's light indicators.
Regarding the range of your 4-year-old EV, it's important to note that battery degradation can occur over time. The estimated range of 78 miles for your 2017 Soul EV seems plausible given its age. It's common for electric vehicle batteries to experience some level of degradation over the years, resulting in a reduced range compared to when the vehicle was new.
Factors such as driving habits, climate conditions, and overall battery health can also affect the range of an EV. If you're concerned about the range or battery degradation, it may be beneficial to have your battery assessed by a certified technician or contact the manufacturer to gather more specific information about your vehicle's battery performance and potential warranty coverage.
Remember that the estimated range provided for a new 2017 Soul EV is based on optimal conditions, and actual range may vary. It's always a good idea to manage your expectations and consider the age and usage of your vehicle when evaluating its range capabilities.
