Electric vehicles such as scooters are reliant upon one or more electrical energy storage devices to not only provide motive power but also power some or all vehicular systems. An electrical energy storage device can be equipped with a number of thermal sensors that provide data indicative of overall and/or localized electrical energy storage device temperature(s) to a controller. In order to maintain the electrical energy storage device in a desired thermal operating range or profile, the controller can selectively alter or control the power distributed or allocated to one or more vehicular systems. Such alteration or control of power allocation may be performed by the controller based upon an assessed degree of vehicular system criticality.
