Advanced Automotive Battery Conference

Please visit Bloomy at Booth #18 for this years conference. Learn about our cell simulation hardware and hardware-in-the-loop (HIL) test system for safe and efficient testing of battery management systems (BMS). Additionally, Bloomy will moderate a roundtable discussion group on BMS Test Approaches and Philosophies. Please join us.

BMS Test Approaches and Philosophies
Date: Thursday, June 27th
Time: 8:30 - 9:30 am
Table: 7
Moderator: Peter Blume, President, Bloomy

• Types of BMS testing: engineering verification, software validation, design verification, HALT/HASS, reliability, and manufacturing test.
• Who’s responsible for BMS testing? The vehicle OEM, the cell/module/pack supplier, and/or the contract manufacturer?
• When should you use cell simulation hardware and when should you use real cells for testing the BMS?
• How many cells or modules should you simulate in order to validate a BMS? When and how should you simulate an entire pack?
• What are the capabilities of hardware-in-the-loop (HIL) testing?
• What are the sources of commercially available BMS testing equipment?

Bloomy will showcase the following:

• The BMS HIL Test System demonstrates a modular and scalable solution for hardware-in-the-loop (HIL) validation testing of battery management systems (BMS) utilizing best-in-class commercial, off-the-shelf components.  Using an Orion BMS as the unit under test, the system utilizes Bloomy’s cell simulation hardware and configurable software architecture to safely and efficiently simulate drive cycles, fault scenarios, cell balancing, thermal runaway, and many other functions. The system provides an intuitive user interface to set the cell model parameters, run automated test scripts, as well as manually control the cells while monitoring the BMS. Some of the modular components include NI PXI instrumentation, VeriStand and TestStand software, VPC mass interconnect, as well as Bloomy’s Battery Simulator 1200, Battery Fault Insertion Unit, and BMS HIL software.
    
• The Battery Simulator 1200 is a 12-cell simulator that is a modular building block for many BMS testing systems. Each cell has individually programmable 0-5VDC levels and sinks and sources current under the BMS’s control. Since it is isolated to 1,000 Volts, you can combine multiple 12-cell simulators in series in order to simulate a larger pack. It is a commercial off-the-shelf product that is FCC and CE certified and available for international export.
