Pilot BT
Increasing demand from the electric vehicle (EV) battery industry has transformed the testing of battery arrays in high-volume production. To meet the most complex technical requirements, Seica designed and developed the PILOT BT Flying Prober for EV battery testing. It is the latest addition to the NEXT> series, making it a validated, verified and fully automated system for testing full-size EV lithium-ion battery packs.
The very large test area (1050 x 865mm) allows not only to handle the many battery configurations currently on the market, but also the ability to manage the configurations of the future. The system's standard configuration includes a Bosch flow-through transport system, but it can also be configured with customized transport solutions integrated into fully automated lines. Regardless of battery technology, type, size or shape, Seica has the solution for high production, reliable and repeatable testing.
Direct measurements on the four measuring heads
The system has up to 4 independent probes driven by synchronous brushless motors (XYZ) to achieve high dynamics. Each of the four heads features a mini fixture that allows up to four individual cells to be inspected in either the X or Y axis orientation in a single movement.
Flying Mini-Fixture: 4-Wire Kelvin Test
The aim of the tester is to measure one of the most important battery parameters: the bond resistance.
Each of the four Mini Fixtures is fitted with:
• Four thermally stabilized and isolated ohmmeters allowing the measurement of the connection resistance of an individual battery cell to the common plate. It is possible to distinguish mΩ resistance values with 1 μΩ resolution and high accuracy
• A 200 MHz Digital Signal Processor (DSP) to process the analog measurements to ensure fast and efficient data processing over a 1 Gigabit Ethernet connection to the system PC.
VIVA>NEXT> software and MES integration option
Like any other Seica solution, the PILOT BT NEXT> test system also uses the VIVA>NEXT> platform, which offers two authentication methods managed via Seica's own graphical editor MY VIEW:
1. The standard Windows authentication2. The new "VIVA user authentication", which the customer can use to select a user with different authorizations.
Since the customer manages the production and material flow via the MES software, the Seica PILOT BT NEXT> can be connected to the customer's MES (Manufacturing Execution System). Through its proprietary adapter, Seica can integrate all of the customer's MES platforms.
