Vehicle operation (e.g., speed, acceleration) may be limited based on various conditions such as a current charge condition of an electrical energy storage devices (e.g., batteries, super- or ultracapacitors), history of such, conditions related to the vehicle (e.g., mileage, weight, size, drag coefficient), a driver or operator of the vehicle (e.g., history with respect to speed, acceleration, mileage) and/or environmental conditions (e.g., ambient temperature, terrain). A controller may control operation of one or more power converters to limit current and/or voltage supplied to a traction electric motor, accordingly.
