Test Station 1. Battery string balancing, estimation and thermal dynamics for battery modules up to 12 series-connected cells.
The hardware for this test station is integrated with A&D I-test software to enable automated testing, cell balancing and a Matlab (Simulink) interface for real-time hardware in the loop simulation.
The hardware consists of:
Bitrode FTV1 Battery Cycler with 60V output and multiple current ranges 200A/20A/2A.
16ft3 Cincinnati Sub-Zero Thermal Chamber enables simulation of various ambient temperature conditions from -45C to 190C (limited to protect batteries).
The battery balancing circuit used to set desired state of charge in battery string with a precision Yokogawa GS610 four quadrant power supply that can sink or source 3A at 12V.
Test Station 2. Battery Cell testing, and 3-cell short stacks.
Arbin BT2000 Battery Cycler capable of two-channel 2-25V and multiple current ranges (200A, 20A, 1A), with auxiliary voltage and temperature inputs and control of an Espec Thermal Chamber.
Arbin BT2000 Battery Cycler (x2) with 32 channels each with a 0-5V voltage range and multiple current ranges (10A, 0.1A, 0.001A). Temperature (and expansion) is recorded with an auxiliary data acquisition system
Test Station 3. 100A 200V Bitrode LCV battery cycler used for the Solar Car Team’s race pack testing.
Test Station 4. Biologic BCS-815, 8-channel 15A cell tester with build-in electrochemical impedance spectroscopy (EIS) capability.
