40 Battery testing The vast majority of driverless vehicles are set to be electric, and simulating the battery system is an essential part of the development process. Multiple large battery packs of different chemistries can be tested in environmental chambers, where the temperature of the environment can be varied as part of the HIL system. This type of HIL system is used to evaluate airflow and the effect of locating the battery in different parts of the structure, to minimise the number of temperature sensors needed by optimising the location of the thermocouples, integrate thermal control systems with the rest of the vehicle and assess the variation in temperature between each cell. All of this can then be combined with the battery management electronics running algorithms for the state of charge and battery health, cell balancing and monitoring, the comms between the battery packs and between the packs and the vehicle, as well as the functional testing and failure response. The future New model-based test generation techniques are being developed to target specific use cases or requirements for machine-learning systems far more effectively than can be done using conventional methods. These techniques can significantly improve verification productivity with higher test coverage in an automated fashion, saving engineering effort. The next step is working with the system developers on real-world uses to see how the models perform, and using this to design and build the next generation of test systems.
