How to improve battery testing efficiency and scalability
The battery pack is the single most costly EV component and has the largest impact on design and performance (size, weight, acceleration, range, charge time, and vehicle life). Join this session next week at the Charged Virtual Conference on EV Engineering, presented by NI and EA Elektro-Automatik, to learn how integrating EA Elektro-Automatik’s bidirectional, regenerative… Read more »
Simplified power analysis on multiple electric motor powertrains
Sponsored by CSM High-performance electric vehicles run with two, three or even more electric motors in the powertrain. Tuning the motor control is complex and requires precise performance analysis in order to test the desired driving characteristics. Early in the development process, the interaction of the individual inverters and electric motors is analyzed on powertrain… Read more »
EV battery testing: Increase lab efficiency and minimize total cost of ownership
OEMs, battery designers and manufacturers, as well as test facilities, face increasing challenges in battery development, testing, and validation. Due to a growing number of devices under test (DUT), test laboratories for cells, modules or packs are becoming larger and more complex. There are many levers to increase efficiency and thus to minimize total cost… Read more »

Swiss city of Basel orders 62 electric buses from Mercedes and Hess
The city of Basel, located on the Rhine at the confluence of Switzerland, Germany and France, plans to fully electrify its bus routes, and power them with 100% renewable energy, by 2027. Basler Verkehrs-Betriebe (BVB)’s fleet currently includes 115 buses serving 14 routes (there are also 135 trams serving 9 lines). The city’s latest tender… Read more »
Predicting And Preventing Thermal Runaway In EV Battery Systems By Utilizing A Unique Measurement System
The precise knowledge of thermal behavior and temperature curves is a prerequisite for the further development of high-performance, high-voltage battery systems. To accomplish this, several hundred temperature measurement points are needed throughout the battery assembly, including between the cells. Traditionally this has been an instrumentation challenge as the enormous quantity of sensors and their signal… Read more »
Optimizing EV Powertrain Through Innovative Measurement Equipment
EV powertrains have to be tested during many development phases, and the system’s overall efficiency is a major contributor to consumer buying criteria. However, the measurement of electrical power consumed throughout the entire vehicle (powertrain, converters, HVAC system, BMS system, etc) as well as for the generation of mechanical power becomes an instrumentation challenge due… Read more »
WAFIOS SpeedFormer three-in-one bending concept for motor hairpin production
WAFIOS has introduced the SpeedFormer, a new approach to the production of hairpins for electric motors, which unites three wire and tube bending techniques into one system. WAFIOS modified and optimized a previously used technique for simple hairpin bends in order to improve production speeds. The company developed and patented a second bending technique, based… Read more »
