Implementation of the method for measuring electric voltages at the elements of Li-ion batteries when working on spacecraft

The method of circuit implementation of the element-by-element voltage control of lithium-ion batteries in the batteries intended for use on spacecraft is described. The method is based on the calculation of the voltage on the elements digitally according to individual measuring channels, implemented on calibrated precision voltage dividers. At the same time, the problem of implementing the storage mode of the battery without dismantling the built-in control system was solved. The data of laboratory tests obtained during the development of the technological sample of the measuring system are given.
