NOVELTY - A battery bank (299) comprises a controller for a battery terminal reconfiguration device. The controller detects that the vehicle is operating in a way that can draw power from battery cells (301-305), and is responsive to detecting that the vehicle is operating to draw power from the battery cells; causes the battery cells to reconfigure into the series connection, and to produce an output voltage equivalent to a sum of all of the battery voltages summed together; and reconfigures the battery connections so that the batteries are connected in parallel.    USE - The battery bank is for a vehicle, i.e. electrically operated vehicle, preferably electric driven automobile (claimed). The vehicle is electric vehicle or hybrid vehicle.    ADVANTAGE - Charging of batteries within an electric-driven vehicle is facilitated. Unused surface areas on a vehicle are used to capture solar energy in a way that stores energy for use in driving the vehicle at a later time. The electric vehicle batteries can be charged in a more economical way. Instead of producing energy that is used for the automobile while the automobile is operational and moving, or trying to scrub the output from the automobile while it is running, surfaces of the automobile are used during times when the automobile is not in use. During the time that the car is parked, its surface area is used to capture solar rays, which are used in a way that may prevent or reduce carbon dioxide pollution. The surface area may be used to power the automobile itself, or may use some kind of carbon dioxide scrubbing. The solar cell for the front window of automobile is movable between its stowed position and an active position where it blocks the entire windshield. When moved into the active position, the solar cell in effect is put into the position of a sun screen, where solar cell is used in place of the sun screen to accept solar energy. A vehicle that is parked in the sun all day could produce 800 W hours with a 100 W solar cell, i.e. almost the entire charging capacity of the battery, thus the battery could be almost fully charged by the sun during this time if the voltage issue could be handled. The charging system for vehicle rearranges the bank of battery cells between a series connection for delivering voltage to a load, e.g. a motor (125); and a parallel connection for being charged. The battery bank can thus be charged by a 12 V battery charger.    DETAILED DESCRIPTION - A battery bank comprises greater than or equal to 3 battery cells, each having a positive battery terminal and a negative battery terminal; a battery terminal reconfiguration device including a first connection part that connects the terminals of the battery cells into a series connection in a first mode, which provides an additive connection of voltages of the battery cells, and connects the cells of the battery into a parallel connection in a second mode, which provides a connection of the voltages of the battery cells that is the same as at least one of the battery cells; and a controller for the reconfiguration device. The controller detects that the vehicle is operating in a way that can draw power from the battery cells, and is responsive to detecting that the vehicle is operating to draw power from the battery cells; causes the battery cells to reconfigure into the series connection, and to produce an output voltage equivalent to a sum of all of the battery voltages summed together; detects a second mode, where the vehicle is not operating in a way that draws power from the battery cells, and is responsive to detecting the second mode where power is not being drawn; and reconfigures the battery connections so that the batteries are connected in parallel. The battery bank further comprises a charging mechanism producing an output voltage that is the same as the voltage of a single one of the battery cells, where charging mechanism is connected to the batteries when configured into the parallel connection. The charging mechanism is a solar cell (300). INDEPENDENT CLAIMS are included for:    (1) a method comprising in an automobile, operating in a first mode where batteries, including a battery bank with greater than or equal to 3 batteries, are connected in series, and the series connected batteries produces a voltage equivalent to an arithmetical sum of the battery voltages, and the arithmetical sum of battery voltages is connected to power an electrically-drivable part on the vehicle; and during a second, charging mode, reconfiguring the batteries into a parallel connection, where all of the batteries are connected in parallel, and charging the batteries using a charger (360) that has an output voltage that is equal to an output voltage of any of the batteries, to charge the parallel connection of the batteries;    (2) a system comprising an automobile housing; a connection to batteries housed within the automobile housing; and a charging system for the batteries; and    (3) an electrically operated vehicle.
