This unit is useful for testing any non-aerospace battery cells.

A charge-control unit was developed as part of a program to validate Li-ion cells packaged together in batteries for aerospace use. The lithium-ion cell charge- control unit will be useful to anyone who performs testing of battery cells for aerospace and non- aerospace uses and to anyone who manufacturers battery test equipment. This technology reduces the quantity of costly power supplies and independent channels that are needed for test programs in which multiple cells are tested. The cost savings that were achieved in a test program are shown in Figure 1. Battery test equipment manufacturers can integrate the technology into their battery test equipment as a method to manage charging of multiple cells in series.
