The desired battery state of charge for a particular electric vehicle can be pre-set by the user. For example, a driver might select 80% as their preferred state of charge for daily commuting, balancing range with battery longevity. This pre-selected percentage allows the vehicle’s charging system to automatically stop charging once the desired level is reached, preventing overcharging and potentially prolonging battery lifespan.
Managing the battery’s state of charge is essential for maximizing the usable life and overall performance of an electric vehicle’s battery pack. Historically, overcharging has been a concern for some battery chemistries. This feature provides drivers with a convenient way to protect their investment and ensure predictable range availability. It also allows for more efficient use of charging infrastructure, as the vehicle will only draw power until the desired level is met.
