2. Series and parallel circuits - Wikipedia

   en.wikipedia.org/wiki/Series_and_parallel_circuits

   A series circuit with a voltage source (such as a battery, or in this case a cell) and three resistance units. Two-terminal components and electrical networks can be connected in series or parallel. The resulting electrical network will have two terminals, and itself can participate in a series or parallel topology.

3. Battery balancing - Wikipedia

   Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]

4. Electric vehicle battery - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle_battery

   Battery packs will always incorporate many discrete cells connected in series and parallel to achieve the total voltage and current requirements of the pack. Battery packs for all electric drive EVs can contain several hundred individual cells. Each cell has a nominal voltage of 3-4 volts, depending on its chemical composition. [citation needed]

5. Hybrid vehicle drivetrain - Wikipedia

   en.wikipedia.org/wiki/Hybrid_vehicle_drivetrain

   The variety of electric-ICE designs can be differentiated by how the electric and combustion portions of the powertrain connect, at what times each portion is in operation, and what percent of the power is provided by each hybrid component. Two major categories are series hybrids and parallel hybrids, though parallel designs are most common today.
