| Sumario: | This master thesis have been done in the circumstance of an internship contract in a Swiss company called Leclanch'e SA. This company is develops, designs and manufactures complete battery storage solutions, covering the entire technology chain. From cells to pack solutions for Hybrid Electric Vehicles (HEVs) and Battery Electric Vehicles (BEVs), as well as the Battery Management System which is the scope of this thesis. Customers of the company have reported errors on the communication interface of the Battery Management System of the company, known as G2 Leclanché BMS. The purpose of the study done in this thesis is to find root causes of problems in the communication interface and its constraints. To this end, faulty BMS samples returned by clients have been analysed and some special testing setups have been prepared in order to study communication constraints as baud rate, cable length, maximum number of nodes, etc. Conclusions extracted from this robustness analysis of communication on G2 Leclanch'e BMS will be used for the next generation of BMS which is being developed by the company. |
