"This is a step that gas-car owners don't really have to deal with, but it will save any EV owner from a lot of cold-weather charging headaches. In the dead of winter, preconditioning your batterymanually heating it up using the car's settingsprior to plugging in can mean much faster DC fast charging times. Since Li-ion batteries like to be relatively warm to rapidly charge or discharge, preconditioning the battery pack before charging gets your EV's battery ready for a speedy charging session."
"Battery preconditioning was once only found on some EVs. Today, on newer models, it's basically a standard feature. Sometimes you can activate it manually, using the settings in your software system. On other cars, preconditioning takes place automatically when you set a DC fast-charging station as a destination in the navigation system. Either way, it'll mean that your car can reach its maximum charge rate much faster."
Electric vehicles lose usable range and charging speed in cold weather, but several strategies can reduce those losses. Preconditioning the battery warms the pack before charging or driving, enabling faster DC fast charging and improved discharge performance because lithium-ion cells charge and discharge more rapidly when relatively warm. Many newer EVs offer battery preconditioning as a standard feature, accessible manually via settings or triggered automatically when a fast-charging destination is set in navigation. Parking indoors and avoiding leaving an EV cold-soaked and unplugged helps preserve range and charging efficiency. These practices improve winter usability and reduce range anxiety.
