EV batteries are liquid-cooled, which helps with controlling the resistance heat from high powered charging. Without liquid cooling, the batteries will be affected to some degree. Today, all EVs capable of rapid charging, are thermally managed by a liquid cooling system.
Rapid charging speeds also slow down and tape off when an 80% state of charge is reached. This protects the battery by putting less strain on cells.
Ideally, you want to rapid charge up to 80%, unplug and continue your journey. You'll protect your battery and be on your way sooner. Waiting for it to reach 100% can take another 30minutes and you'll be blocking a rapid charger. If you want 100% come off the charger and plug it into a Fast charger to complete the charge.
