A well-balanced pack lasts longer and delivers better performance.įor an inline package, cells are selected and stacked with solder in between them. Active balancing can also be performed by battery balancer devices which can shuttle energy from strong cells to weaker ones in real time for better balance. Battery regulators are sometimes used to keep the voltage of each individual cell below its maximum value during charging so as to allow the weaker batteries to become fully charged, bringing the whole pack back into balance. When a pack contains groups of cells in parallel there are differing wiring configurations which take into consideration the electrical balance of the circuit. Interconnects are also found in batteries as they are the part which connects each cell, though batteries are most often only arranged in series strings. Rechargeable battery packs often contain a temperature sensor, which the battery charger uses to detect the end of charging. ![]() The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.Ĭomponents of battery packs include the individual batteries or cells, and the interconnects which provide electrical conductivity between them. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. Automobile battery pack consisting of 28 Optima Yellow TopsĪ battery pack is a set of any number of (preferably) identical batteries or individual battery cells.
