Testing conformance and interoperability of EVs and charging infrastructure

EV and EVSE manufacturers and providers are striving to reach that magical tipping point where range, charging time, availability, safety, and price come together to help EVs become the consumer’s preferred choice versus conventional gasoline cars. However, any single design fault in this complex ecosystem will cost money and delays, and no one wants to… Read more »

bdtronic to launch new oven for curing power electronic’s potting compounds

German mechanical engineering, process specialist and automated dispensing cell manufacturer bdtronic plans to offer standardized industrial ovens for heat-treating the components found in power electronics, on-board EV chargers, autonomous vehicle sensors and automotive tire-pressure sensors. The ovens are designed to cure epoxy resins, polyurethanes and silicones, as well as to preheat components. bdtronic’s continuous ovens… Read more »

Infinitum Electric brings its PCB stator technology to EV motors

Infinitum Electric says its axial flux motors with printed circuit board stators offer weight reduction, cost reduction and efficiency gains. Batteries are getting a lot of media coverage these days—they represent a rapidly-developing technology that’s seen as the key to the electrification of transport. Motors, however, are considered a fairly mature technology, and the humble… Read more »

Electrical steel shortage could slow OEM electrification plans

A new report from IHS Markit foresees the possibility of an electrical steel shortage, beginning in 2025, that could pose a threat to automakers’ electrification plans. Electrical steel is an iron-silicon alloy with magnetic characteristics that make it well suited for electric motors. Non-Oriented Electrical Steel (NOES) is one form that’s used to make motors….

AVL’s new line of test equipment for a trouble-free EV charging experience

The charging experience is one of the largest differences between vehicles with a battery and vehicles with a fuel tank. The core charging requirements are established and standardized, however, both the technology and applications are still in the early stages of maturity. Therefore, they are subjected to intense market pressure to expand, evolve, and improve…. Read more »

New battery inspection technologies: X-ray CT and Microscopy

Battery manufacturers face quality and process control challenges when battery components need to be inspected without being destroyed. The cells are inspected to map the electrode’s microstructure in 3D, the heterogeneities, foil stacking, welding joints, contacts, and their effect on battery aging and performance through several cycles of charging and discharging. X-ray microscopy and computed… Read more »

In-line inspection of EV transmission components

Join this session next week at the Charged Virtual Conference on EV Engineering, presented by DWFritz, to learn about the need for and application of in-line inspection for key transmission components for EVs. Specifically, we will discuss market needs and 3D inspection case studies for inspecting gears, traction motor, brakes and clutches. The case study… Read more »

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 »

Simplifying EV traction inverters emergency power supply architecture

The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »

Lower real EV inverter cost without compromising safety, quality, or test coverage

In the evolving world of eMobility one thing remains constant – the inverter is the heart and soul of electric vehicles. When it comes to testing inverters, the trend has been to pull tests further up the development cycle, using virtualization to simulate components at lower costs and test scenarios faster than in-vehicle field testing….
