Designing battery management systems (BMS) for electric vehicles (EVs) is one of the more complex design challenges facing engineers, and the most important design consideration is BMS IC selection. This article examines the top three BMS design considerations, including a close look at battery pack architectures, inter-module communications or daisy chaining BMS modules, and the optimum PCB layout configuration.

For testing ESS Battery Management Systems (BMS), the use of “virtual” batteries is proving to be an effective alternative to the use of real batteries. They allow the engineer to avoid the risks of damage to the batteries – and subsequent costs – while testing and optimizing the BMS design in a close-to-reality loading environment. Maplesoft, a developer of battery modeling technology, recently partnered with ControlWorks, Inc. of South Korea to develop a turn-key BMS system. The end result was a battery model capable of being configured to represent a stack of up to 144 cells that can be connected in any combination of parallel and series networks.

Battery Cell Voltage Measurement and Balancing system performs high-precision measurement and control of cell voltages in Li-ion batteries.

New rapid control prototyping (RCP) offerings from dSPACE are said to simplify the development of critical battery management algorithms by enabling precise, fast measurement and control of cell voltages for modern Li-ion batteries.

Quick iterations with maximum control

Battery management systems (BMS) interact with several vehicle systems such as the powertrain, energy management, vehicle safety, infotainment, etc. These systems cannot be developed in isolation, but require easy-to-use, in-vehicle rapid control prototyping (RCP) systems that allow quick iterations with maximum control capability. dSPACE is extending its RCP portfolio to fulfill this need by introducing its Battery Cell Voltage Measurement and Balancing system.

dSPACE’s newest Automotive Simulation Models (ASM) simulation package is a battery model for simulating high-voltage rechargeable batteries. The model is designed to virtualize rechargeable lithium-ion, nickel-metal hydride (NiMH) and lead batteries used for the electrification of vehicle drivetrains.

The model facilitates function development for battery management systems (BMS) and the testing of close-to-production electronic control units (ECUs). Model-in-the-loop (MIL) simulations in MathWorks’ Simulink and hardware-in-the-loop (HIL) simulations on the simulator are used for this.
