Jaguar has several new advanced battery systems in development. Their current electric vehicle, the Jaguar I-PACE, features a 90 kWh lithium-ion battery with a range of approximately 234 miles. The system supports DC fast charging, allowing an 80% charge in about 45 minutes. This model also integrates features to optimize battery life, such as intelligent temperature management.
If the battery charging infrastructure is in place, EVs have reached the point where they're practical. Luddites and troglodytes will no doubt need to be dragged kicking and screaming into the era of electric vehicles, but that's always been the case with new technologies.
