The increasing demand from the Electric Vehicles (EV) battery industry for electric cars has changed the high-volume production battery arrays test. To meet the most complex technical needs, Seica has designed and developed the PILOT BT flying prober for EV Battery Test, the latest addition to the NEXT> Series, which is a validated, verified and completely automated system to test full-size EV lithium ion battery packs. Its very large test area (1050 x 865 mm) not only enable it to handle the many battery configurations currently on the market, but the capacity to manage the configurations of the future. The standard system configuration includes a pass-through conveyance by Bosch, but it can also be configured with customer-specified conveyance solutions integrated into completely automated lines No matter the battery technology, type, size or shape, Seica has a solution for high production, reliable, and repeatable test. Direct measurements on the four flying heads The system features up to 4 independent test heads driven with synchronous brushless motors (XYZ), to provide a high-level dynamic response. Each one of the four heads features a mini fixture to test up to four individual cells in a single movement in either an X or Y axis orientation. Flying mini-fixture: 4-wire kelvin test The aim of the tester is to measure one of the most important parameters of the battery: the bonding resistance. • Four thermally stabilized and insulated resistance meters, which enable the measurement of the bonding resistance of a single battery cell to the common plate. It is possible to discriminate mΩ resistor values with 1 μΩ resolution and high accuracy.
