Dekra's Innovative Rapid Battery Assessment Tool Promises Accurate Electric Vehicle Evaluations in Under 17 Minutes

In the final session of a set, the speaker has 17 minutes to discuss advancements in rapid battery assessment for electric vehicles—a timeframe analogous to customer expectations for quick battery health appraisals. The company Dekra, known for vehicle testing and certification, aims to address issues with used car batteries. As EVs become more prevalent and their batteries remain costly (up to 40-50% of a new vehicle's value), accurate assessments are crucial. Historically, data from Battery Management Systems (BMS) lacked standardization and reliability. Early attempts using internal resistance metrics were inaccurate by about 50%. After extensive research, accuracy improved significantly to within 2.5%. Dekra's refined process involves four steps: identifying the vehicle on-site, reading OBD data, interacting with the battery (measuring impedance), and calculating state-of-health through an online system—all achievable in under 15 minutes. However, challenges persist due to varying international regulations and environmental conditions affecting test consistency. Innovations now allow assessments without driving; instead utilizing controlled charging methods as a solution.

Talk of session: EV Battery Development

Batteries are at the heart of any electric vehicle. Their design determines the vehicle's range, charging speed, performance in cold weather, fire safety and many other properties. The speed of development has been immense, as new cell chemistries such as LFP, sodium-ion and solid state batteries are pushing into the market. Significant progress has been made with monitoring battery usage with a view to design optimization so that the battery performance is maximized without accelerating the ageing process. In this session, we share insights on the performance of today's vehicle batteries and future technological developments.
