Free seminar: Mapping motor efficiency quickly and dynamically with HBM eDrive
Sponsored by HBM The eDrive solution from HBM acts as both a power analyzer and data acquisition system. It has the ability to record ALL signals along the drive train (power source, inverter, torque and speed of a motor, temperatures, CAN signals, strain, vibration, etc.) with a single instrument. This greatly reduces the test complexity and results… Read more »
Daimler’s RIZON electric trucks achieve full homologation in the US
Daimler Truck, which launched electric truck brand RIZON in May, says its Class 4 and 5 medium-duty models have received full US homologation, which is the process of certifying that a vehicle complies with the technical and legal requirements to be deemed roadworthy and safe for public use. RIZON has received certification from the EPA… Read more »
