Measure the internal resistance and discharge platform of a single battery, as well as the process level of the lithium battery combination, and see the specific product requirements for battery performance.
The consistency of the lithium battery pack refers to the convergence of the important characteristic parameters of a set of lithium batteries. The consistency of the battery refers to the weight of the battery and the consistency of the voltage. The multiple strings of batteries in the same battery pack, each parameter, the best. All in a small range is good for consistency.
The higher the consistency of the capacity, internal resistance, charge and discharge curves of batteries produced by the same material and the same process, the better. It is critical that the battery can form a battery pack on a large scale. The larger the battery pack, the higher the consistency requirement.
