The disclosure provide a system and method for controlling an electronic vehicle battery according to user-selected strategies. Multiple battery operation modes (e.g., general, performance, and efficiency) may be stored, each offering distinct parameters for charging and discharging. A battery management system may present these modes to the driver, enable adjustments such as fast charging current and state-of-charge regions. A user may select a target usage period or performance preference, and the system calculates an expected battery life to guide the choid. The expected battery life may be then displayed—often as a table or graph—so the user can intuitively compare trade-offs among different modes. This adaptive approach manages battery health and optimizes performances based on the user's need and the real-word operation of the vehicle.
