Energy density of batteries increases by about 7% per year. So within a decade battery range should match the average passenger car range. At that point, continuous driving is the last challenge. Fast chargers would need to scale with battery capacity for a roadtrip use case of say 5 hours of driving between stopping for meals and charging.
