Energy Efficient Electric Vehicles

Vehicle battery data is collected and transmitted using an advanced and secure data logger and transferred encrypted to a data broker cluster; the data is stored in an optimized database. All of this is happening while the Electric Vehicle Fleet (EVF) is driving. In the backend the data is analysed and used for the improvement of functionality (e.g. time left to charge), safety or autonomous driving (e.g. Fail-operation in Battery/BMS). Such improvements are sent back to the EVF, where the infrastructure is used in the opposite direction. The vehicles in the EVF are now consumers and consume the software update. All of this still happens in an encrypted way, ensuring the integrity of the software update. A further topic is the handling of the impact of low state-of-charge (Keyword “safe energy supply”) on autonomous functionalities. Necessary updates or system decisions can be done over-the-air; safety-relevant warnings can be communicated to the driver. The generated data leads to a better estimation of battery remaining useful life (RUL), battery failure prediction and error management.
