A utility cart includes a stored energy device that can be in the form of a Lithium Ion battery pack. The battery pack can include a main power output useful to drive high voltage components as well as the electric motor for motive power. The battery pack can also include one or more auxiliary outputs useful to provide auxiliary power to various other components. The auxiliary outputs can be either low and/or high voltage outputs. An auxiliary DC/DC output can be used to step down high voltage of the Lithium ion battery pack to lower voltages. A motor controller supply can also be provided as an auxiliary output to provide some power to a motor controller.

Auxiliary power output for battery management system

A battery charger detection system is provided. The battery charger detection system includes a battery charger, an indicator, and a controller. The controller detects an initial electrical coupling of the battery charger to a battery and measures a first voltage of the battery upon the electrical coupling. The controller further measures a second voltage of the battery and actuates the indicator in response to both a continued electrical coupling between the battery charger and the battery and the second voltage being less than or equal to the first voltage after a predetermined length of time.

Inoperable battery charger detection and notification for electric vehicles

A utility vehicle includes an electric motor constructed to provide motive power to the utility vehicle; a lithium ion battery pack coupled to the electric motor at a first voltage and operative to provide electrical power at the first voltage to the electric motor for driving the utility vehicle, the lithium ion battery pack including a DC/DC converter constructed to output electrical power at a second voltage; and a vehicle control module (VCM) coupled to the DC/DC converter, constructed to operate at the second voltage and constructed to control at least some operations of the utility vehicle.

Utility vehicle with vehicle control module

Speaker basket enclosure

An auditory optimization system that provides a plurality of acoustic arrangements that can specify a plurality of acoustic parameters implementable by respective acoustic control systems of one or more vehicles. The acoustic parameters can be implemented by a controller of the vehicle(s) to control an audio characteristic of a sound emitted through the speaker(s) of the vehicle, such as a volume range, based on the acoustic category associated with the sound. Operation of the system can include the selection of one of the plurality of acoustic arrangements, as well as a selection of the vehicle(s) to receive the acoustic parameter(s) associated with the selected acoustic arrangement. The acoustic parameters of the selected acoustic arrangement can be transmitted via a telematics network to a controller of the identified vehicle(s), which can implement the transmitted acoustic parameters.

Dynamic acoustic control and vehicle auditory optimization

A unique method for charging a battery includes comparing a parameter to a limit, wherein the parameter relates to previous charging of the battery; determining a current state of the battery; and performing a next charging cycle based on the comparison and/or the current state of the battery. A unique system includes a vehicle, a battery, and a charging system for charging the battery. The charging system includes a controller for determining whether the battery is in short term storage or long term storage; starting a new charge cycle after a first amount of reduction in the charge of the battery if the battery is in short term storage; and starting the new charge cycle after a second amount of reduction in the charge of the battery if the battery is in long term storage.
