The automotive industry is facing a major shift as electric vehicles are starting to replace petroleum-based cars. As customers begin to trade in their gasoline-based autos for electric buggies, they will start to expect similar, even superior performance from their latest rides.
To meet this demand, engineers must design batteries and battery management systems (BMS) that can control a car’s engine, air conditioning, heating, infotainment systems and more.
A battery management system (BMS)
controls a lot more than just a battery
and its motor. It is an integral part
of every electronic system in the car
A BMS is the brain of the electric vehicle’s power systems. It has many functions that include:
In short, the BMS design ensures that the driver experiences a smooth, safe and efficient ride. It also keeps the driver aware of the electric vehicle’s condition and can enact emergency procedures to prevent damage or catastrophic failures.
ANSYS Twin Builder can be used to create system models
Engineers can design a BMS by first creating a system model in Twin Builder. Next, engineers can use SCADE Suite to create and verify the BMS’s embedded controls software, in parallel with Ansys medini analyze, to ensure its safety. These three tools can then be used to virtually prototype the BMS and ensure that it is working properly.
