Advanced cell simulation for passive- and active-balancing BMS testing
The Advanced Battery Simulator 800 provides eight 5V, 5A cells to simulate battery sink and source characteristics for testing Battery Management Systems (BMS). Over 200 cells can be stacked in series to safely simulate battery stacks of up to 1000 VDC. Built-in voltage and current readback sensing per cell provide highly accurate simulation as well as live data readings without external monitoring equipment. Onboard auxiliary I/O can be used to simulate cell and module temperature sensors and provides additional analog and digital I/O. Integrated faulting relays facilitate open circuit, cell short, and reverse polarity faults. Safe operation is guaranteed by compliance to the IEC 61010-1 product safety standard and the use of robust, reinforced/double insulation between the high voltage cell domains and the low voltage communication interfaces and auxiliary IO domains.

The Advanced Battery Simulator 800 is BLOOMY’s next generation battery cell simulator (aka emulator) for testing battery management systems (BMS) and other battery-sensitive devices for EVs, electric aircraft, stationary ESS and more! Its best-in-class performance includes sub-1mV cell voltage accuracy across its 0-5V range, extremely low noise, 5A of current sink/source capability per cell, integrated short, open, and polarity-reversed cell faults, cell temperature and pack current sensor simulation, and 1,000V of reinforced isolation. In addition, the Advanced Battery Simulator 800 performs onboard cell model execution with kilohertz loop rates, and has an intuitive SCPI application programming interface. The ABS is remotely monitored and controlled via Ethernet, CAN, and RS-485 using the included software drivers for C/C++, CAN DBC, Python, NI LabVIEW, and more.
Onboard cell model execution facilitates distributed, asynchronous execution across multiple instruments, allowing virtual unlimited scaling of battery hardware-in-the-loop (HIL) simulator applications. By combining the simulated cells, models, faulting, and sensors onboard the Advanced Battery Simulator 800, as well as the ability to series-connect multiple instruments, the Advanced Battery Simulator 800 cohesively and comprehensively simulates a battery with minimal supervision from a host computer. The dense feature set in a modular 1.75" (1RU) package makes BLOOMY’s Advanced Battery Simulator 800 the most advanced battery simulator now available!

The Advanced Battery Simulator 800 introduces a new level of flexibility and safety to the laboratory environment with built-in fault modes for each cell! Each of the Advanced Battery Simulator 800’s simulated cells has one normal state and three fault states:
Normal: In normal operation, all terminals of each cell remain connected. The battery management system (BMS) or other unit under test is able to sense each cell’s state and to control cell balancing and other pack characteristics.
Open-Wire: During an open-wire fault state, the ABS800 physically disconnects the simulated cell’s battery management system terminal. This fault simulates the real-world condition of a broken sense wire. The simulated battery pack’s other connections may or may not remain intact during this fault depending on how the BMS and Advanced Battery Simulator 800 are connected.
Short-Circuit: The short-circuit fault state causes the Advanced Battery Simulator 800 to apply a physical short circuit between the cell’s negative terminal and the cell’s BMS terminal. This condition may arise, for example, through abrasion or when insulation melts in an overheated battery pack.
Reverse Polarity: The Advanced Battery Simulator 800 reverses the polarity of the simulated battery cell when the cell is in this fault condition. A battery can acquire a negative polarity if the BMS has allowed a completely discharged cell to become charged by other cells, thus acquiring a negative charge.
Using the built-in faulting capability of the Advanced Battery Simulator 800 ensures the utmost safety and reliability of your product.
