Engineers are mobilizing at a rapid pace to meet the demands and challenges presented by the shift to more widely adopted battery powered devices and transportation. Prenscia has partnered with customers and researchers to deliver insights into the mechanical and durability aspects, electrical and signal processing aspects, as well as statistical and reliability aspects of these highly advanced vehicles for a more in-depth understanding of how the range and overall efficiency of the vehicle can be improved.
Like their thermal-engine counterparts, electric vehicles are susceptible to structural fatigue failures. The mechanical complexity of the battery structure and its mountings also give rise to significant additional fatigue failure issues. Insights into these structural and vibration-induced failures enable engineers to eliminate the risk of fatigue failure, improve the durability of electric-engines, and increase vehicle reliability.
The theoretical and real-world range of an electric vehicle may vary significantly. In order to maximize the range and overall efficiency of the vehicle, it is necessary to understand and characterize how the vehicle will be used and determine through meticulous measurement and analysis where the losses occur.
All electric vehicle batteries degrade overtime. Its performance, however, varies by model and external conditions such as usage, temperature, and charging methods. In order to improve the overall reliability of the battery system and avoid excessive warrantee exposure, it is important to understand both the mean life and the statistical distribution of lives for the battery. Furthermore, understanding how the battery degrades over time will lead to significant improvements in battery design, reliability and vehicle efficiency.
