Battery Pack Test Systems
Advanced battery systems power a wide array of products, from cell phones to electric vehicles. As the demand for effective electrical and thermal management of battery pack components rises, AMTech steps in with its expertise in designing, building, and programming automated systems for testing and validating various battery pack and battery management system (BMS) designs.
Modular Battery Test Platform
AMTech’s modular Battery Test Platform incorporates open software and hardware technologies, along with flexible and reliable subsystem components and instruments. This approach allows for the creation of systems that are completely customizable to the end user’s specifications.
Vehicle Battery Pack Testing
AMTech’s Battery Pack Test Systems facilitate battery design and research and development for national laboratories, research institutions, and major automotive manufacturers and their suppliers. These systems evaluate the battery as a complete system and validate a comprehensive range of functionalities, including:
- Power performance, capacity, DCR/internal resistance
- Contactor and safety interlock functions
- Isolation/insulation resistances
- Reporting of operating data through external communication interfaces (usually CAN)
- Cell voltages
- Pack/cell temperatures
- State of charge (SOC)
- Faults/Diagnostic Trouble Codes (DTCs)
- Electrical characteristics/continuity of internal pack wiring/signals
- Cooling system operation
Battery Pack Testing Regimens
AMTech test stands accommodate multiple battery pack testing regimens, including:
- Functional testing: to verify all battery pack communication and data reporting, safety features, wiring, and component functions
- High-power battery cycling: to evaluate the power characteristics of a battery pack
- Environmental/endurance testing: to test battery pack functions while exposed to harsh/strenuous conditions for extended periods
High Power Battery Cycling
Battery Pack Test Systems by AMTech can include battery pack cycling, executing standard and customized charge and discharge profiles. These systems can integrate with battery cyclers and power supply/DC load platforms from various manufacturers, including:
- Aerovironment Cyclers
- TDK-Lambda
- NH Research
- Sorensen/Ametek
- Amrel
- TDI
- Dynapower
BMS Test Systems
AMTech’s BMS Test Systems support the development of various batteries, including those for consumer electronics, electric vehicles, and space applications. These systems evaluate a comprehensive range of BMS functionalities, including:
- Measurement accuracy
- BMS power consumption
- Cell balancing functions
