For over 10 years I have worked in the EV and ESS battery testing field. Located in Germany, Japan and China I was involved in the planning, building and ramping up of several large battery test labs. Besides internal organisation and optimization of the labs, I was also in close discussion with customers to optimize their battery validation test plans, so they achieve faster validation of their developments with lower costs. Now I help customers to build and operate battery testing labs more efficiently and support battery developers to validate their developments faster.
