Serial and Parallel Battery Configurations and Information. BU 3. 02 Configuraciones de Bateras en Serie y Paralelo EspaolLearn how to arrange batteries to increase voltage or gain higher capacity. Batteries achieve the desired operating voltage by connecting several cells in series each cell adds its voltage potential to derive at the total terminal voltage. Parallel connection attains higher capacity by adding up the total ampere hour Ah. Some packs may consist of a combination of series and parallel connections. British actor goes all in and delivers a fierce performance as the Prime Minister that saved Britain and the world from fascism. Diagnosing Motherboard, CPU and memory related performance issues from frrezes and reboots to poor performance. SPG stands for special performance group. The difference between the turbo cars and the SPG cars is the suspension, the ground effects package and the rims. Laptop batteries commonly have four 3. V Li ion cells in series to achieve a nominal voltage 1. V and two in parallel to boost the capacity from 2,4. Ah to 4,8. 00m. Ah. Such a configuration is called 4s. Insulating foil between the cells prevents the conductive metallic skin from causing an electrical short. Most battery chemistries lend themselves to series and parallel connection. It is important to use the same battery type with equal voltage and capacity Ah and never to mix different makes and sizes. A weaker cell would cause an imbalance. This is especially critical in a series configuration because a battery is only as strong as the weakest link in the chain. An analogy is a chain in which the links represent the cells of a battery connected in series Figure 1. A weak cell may not fail immediately but will get exhausted more quickly than the strong ones when on a load. On charge, the low cell fills up before the strong ones because there is less to fill and it remains in over charge longer than the others. On discharge, the weak cell empties first and gets hammered by the stronger brothers. Cells in multi packs must be matched, especially when used under heavy loads. See BU 8. 03a Cell Mismatch, Balancing. Single Cell Applications. The single cell configuration is the simplest battery pack the cell does not need matching and the protection circuit on a small Li ion cell can be kept simple. Typical examples are mobile phones and tablets with one 3. V Li ion cell. Other uses of a single cell are wall clocks, which typically use a 1. V alkaline cell, wristwatches and memory backup, most of which are very low power applications. The nominal cell voltage for a nickel based battery is 1. V, alkaline is 1. V silver oxide is 1. V and lead acid is 2. V. Primary lithium batteries range between 3. V and 3. 9. V. Li ion is 3. V Li phosphate is 3. V and Li titanate is 2. V. Li manganese and other lithium based systems often use cell voltages of 3. V and higher. This has less to do with chemistry than promoting a higher watt hour Wh, which is made possible with a higher voltage. The argument goes that a low internal cell resistance keeps the voltage high under load. For operational purposes these cells go as 3. V candidates. See BU 3. Confusion with VoltagesSeries Connection. Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3. V Li ion cells in series, also known as 4. S, to produce 1. 4. V nominal. In comparison, a six cell lead acid string with 2. Vcell will generate 1. V, and four alkaline with 1. Vcell will give 6. V. Figure 2 Series connection of four cells 4s. Adding cells in a string increases the voltage the capacity remains the same. Courtesy of Cadex. If you need an odd voltage of, say, 9. Ni. MH or Ni. Cd, or three Li ion in series. The end battery voltage does not need to be exact as long as it is higher than what the device specifies. A 1. 2V supply might work in lieu of 9. V. Most battery operated devices can tolerate some over voltage the end of discharge voltage must be respected, however. High voltage batteries keep the conductor size small. Cordless power tools run on 1. V and 1. 8V batteries high end models use 2. V and 3. 6V. Most e bikes come with 3. V Li ion, some are 4. V. The car industry wanted to increase the starter battery from 1. V 1. 4V to 3. 6V, better known as 4. V, by placing 1. 8 lead acid cells in series. Logistics of changing the electrical components and arcing problems on mechanical switches derailed the move. Some mild hybrid cars run on 4. V Li ion and use DC DC conversion to 1. V for the electrical system. Starting the engine is often done by a separate 1. V lead acid battery. Early hybrid cars  ran on a 1. V battery electric vehicles are typically 4. V. Such a battery needs more than 1. Li ion cells connected in series. High voltage batteries require careful cell matching, especially when drawing heavy loads or when operating at cold temperatures. With multiple cells connected in a string, the possibility of one cell failing is real and this would cause a failure. To prevent this from happening, a solid state switch in some large packs bypasses the failing cell to allow continued current flow, albeit at a lower string voltage. Cell matching is a challenge when replacing a faulty cell in an aging pack. A new cell has a higher capacity than the others, causing an imbalance. Welded construction adds to the complexity of the repair, and this is why battery packs are commonly replaced as a unit. High voltage batteries in electric vehicles, in which a full replacement would be prohibitive, divide the pack into modules, each consisting of a specific number of cells. If one cell fails, only the affected module is replaced. A slight imbalance might occur if the new module is fitted with new cells. See BU 9. 10 How to Repair a Battery Pack. Figure 3 illustrates a battery pack in which cell 3 produces only 2. V instead of the full nominal 3. V. With depressed operating voltage, this battery reaches the end of discharge point sooner than a normal pack. The voltage collapses and the device turns off with a Low Battery message. Figure 3 Series connection with a faulty cell. Faulty cell 3 lowers the voltage and cuts the equipment off prematurely. Courtesy of Cadex. Batteries in drones and remote controls for hobbyist requiring high load current often exhibit an unexpected voltage drop if one cell in a string is weak. Drawing maximum current stresses frail cells, leading to a possible crash. Reading the voltage after a charge does not identify this anomaly examining the cell balance or checking the capacity with a battery analyzer will. Parallel Connection. If higher currents are needed and larger cells are not available or do not fit the design constraint, one or more cells can be connected in parallel. Most battery chemistries allow parallel configurations with little side effect. Figure 4 illustrates four cells connected in parallel in a P4 arrangement. The nominal voltage of the illustrated pack remains at 3. Cortez Peters Keyboarding Program. V, but the capacity Ah and runtime are increased fourfold. Figure 4 Parallel connection of four cells 4p. With parallel cells, capacity in Ah and runtime increases while the voltage stays the same. Courtesy of Cadex. A cell that develops high resistance or opens is less critical in a parallel circuit than in a series configuration, but a failing cell will reduce the total load capability. Its like an engine only firing on three cylinders instead of on all four. An electrical short, on the other hand, is more serious as the faulty cell drains energy from the other cells, causing a fire hazard. Most so called electrical shorts are mild and manifest themselves as elevated self discharge. A total short can occur through reverse polarization or dendrite growth.
