    Abstract: A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To allow easy and convenient access to empty portable electrical energy storage device compartments within the vehicles, if the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as a key fob or other wireless device of a user, an empty portable electrical energy storage device compartment that is closed or locked, is unlocked, unlatched or opened automatically. Also, if the portable electrical energy storage device compartment is in another desired state to have the compartment unlocked, such as having a portable electrical energy storage device in the compartment that has a charge level below a particular threshold, the compartment will likewise be unlocked, unlatched or opened automatically.

  • Patent number: 11117490
    Abstract: In a vehicle power supply device, a switch unit switches mutual connection among first to fourth batteries. When supplying electric power from the first to fourth batteries to a motor, a switch controller controls the switch unit and forms a backup battery corresponding to at least one of the first to fourth batteries that does not supply electric power to the motor and a serial battery group for supplying electric power that has the remaining batteries, except for the backup battery, connected in series. The switch controller supplies electric power from the serial battery group for supplying electric power to the motor, and, when a predetermined condition is satisfied, sequentially switches between a battery included in the serial battery group for supplying electric power and the backup battery.
