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 »

UnitedSiC launches new version of FET-jet component selection tool

UnitedSiC has launched version 2 of its FET-jet calculator, a tool used to select Schottky diodes and field-effect transistors (FETs). The user selects the topology of the desired AC-DC or DC-DC converter, isolated or non-isolated. Changing between continuous, critical, or discontinuous modes is automatic. The input, output, and power required are selected, and the tool then… 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 »

GM and Wolfspeed partner to develop silicon carbide power devices

General Motors and Wolfspeed (formerly Cree) have entered an agreement to develop and provide silicon carbide power devices for GM’s electric vehicle programs. The silicon carbide will be used in the integrated power electronics contained within GM’s Ultium Drive units. The silicon carbide power devices will be produced at Wolfspeed’s 200 mm-capable Mohawk Valley Fab… 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….
