Lithium-ion batteries in parallel charging
Aims to increase the capacity of the lithium-ion batteries in parallel, therefore, parallel charging lithium-ion batteries compared with single lithium ion battery with different design features, mainly on the consistency in design and parallel battery charging current. Characteristics of lithium-ion batteries in parallel are: constant voltage, battery capacity addition, resistance decreases battery life extended. Parallel charging is the core content of the size and role of the current. According to the theory , current is equal to the current of each branch and, therefore, have been combined as the battery n parallel li ion battery to achieve with the same single-cell charging efficiency, charging current for a number of current lithium-ion batteries, and Ohm's law: I=U/R under the formula, the design is reasonable. However, the parallel battery internal resistance will also change according to the parallel resistance formula, two parall...
