BMW Electric Vehicle next generation battery test bench
Continuous testing for future improvement is one of BMW’s methods of ensuring their vehicle standards remain high. The core aspect of this project was to create and define a toolchain to optimise BMW’s current test environment for battery powered electric vehicles. The toolchain allows engineers to create complex test scenarios for a product by combining several standard test cases, with varying parameters. A well-designed toolchain will allow the quick and easy development of new test scenarios to be executed on the test bench containing the test battery. The user interface of the toolchain is provided in the cloud to allow easy distribution of tests across all users and test benches. The design also incorporates a system to ensure the tests on the cloud and the tests located at the test bench remain synchronised.
The project described in this report was completed as a full-time internship position over eight months at BMW’s research and development headquarters in Munich Germany, known as the FIZ (Forschungs- und Innovationszentrum or in English: Research and Innovation Centre). According to the 2015 Sustainable Value Report, during the 2015 period BMW sold 2,247,500 vehicles of which 29,513 vehicles (or 1.3%) were from the BMW i series. The BMW i series consists of the i3 and i8 vehicles which have been designed as environmentally sustainable electric vehicles. There was an increase of 65% in sales of these i series vehicles from 2014, showing just how popular this range is becoming. In 2015, BMW had a profit of €9,224 million euro (profit before tax) from their vehicle sales, of which €5,169 million euro was then spent on research and development. This allows BMW to conduct significant testing and analysis of their vehicles thus helping to maintain their reputation as a prestigious and high quality vehicle manufacturer.
