Abstract

Children'"'"'s ride-on vehicles having charge indicator assemblies that are adapted to provide at least a visual indication of the state of charge of the ride-on'"'"'s battery assembly. The vehicles are reduced-scale vehicles, often formed substantially from molded plastic, that are sized for use by children and which include battery-powered motor assemblies. The vehicles include a charge indicator assembly that is adapted to selectively assess an input voltage from the battery assembly and provide an output representative of the relative state of charge of the battery assembly. In some embodiments, the charge indicator assembly includes a charge indicator module that is mounted on the vehicle'"'"'s body, optionally in a position to be accessed by a child operating the ride-on, and which includes a button or other actuator adapted to cause the charge indicator assembly to assess the state of charge of the battery assembly.
