Configure Battery Pack Simulator for Battery Management System (BMS) Hardware-in-the-Loop (HIL) Testing

Battery Management Systems Testing

A Battery Management System (BMS) is an embedded unit performing critical battery functions, including cell monitoring and balancing, pack charge and discharge control, safety, and communications. The BMS must be tested early in development to optimize control algorithms, as well as during manufacturing to ensure reliable functionality. Bloomy’s family of BMS test systems provides a consistent platform for engineers to bring a BMS to market faster, and more reliably.

Battery Simulator

1200 - Bloomy Controls, Inc.

The Battery Simulator 1200 provides isolated channels to simulate battery sink and source characteristics often used for testing a Battery Management System (BMS). The instrument can be used standalone with the soft front panel, or integrated into a larger test system. Its proper industrial cooling and cell channel isolation allows units to be easily stacked, providing solutions with over 200 channels of simulation capability. The built-in channel voltage and current readback reduces the need for external monitoring equipment.

Battery Fault Insertion Unit

Bloomy Controls, Inc.

The Battery Fault Insertion Unit (FIU) provides intelligent switching of cell-simulation channels for the Battery Simulator 1200. The switching capability enables simulation of open-circuit and short-to-rail fault conditions on any cell channel for the purposes of battery management system (BMS) testing. Additionally, a four-wire auxiliary input allows you to connect an external digital multimeter (DMM) instrument to any cell channel for very high-accuracy bypass current and cell voltage measurements. Each FIU provides 24 independently-programmable cell-switching channels for one or two 12-cell Battery Simulator 1200 units. Additional Battery Simulator 1200 and FIU instruments can extend functionality up to 120 series-connected cell channels.
