What is a transient voltage suppressor diode?
The transient voltage suppressor diode protects electronic signal lines and interfaces designed to operate within specific voltage ranges. Exceeding these limits exposes sensitive semiconductors to disturbances or permanent damage. A common protection method is this specialized diode, often abbreviated as TVS. Standard ESD protection devices are made to work with high-voltage, low-energy pulses that last…
Integrated system simplifies battery testing
A new integrated battery test system combines environmental chambers, cyclers, and fixtures into a single, pre-configured unit, designed to reduce setup and integration time. The system combines hardware and control software from Associated Environmental Systems (AES) and MACCOR Inc., allowing test facilities to begin operations shortly after delivery rather than waiting through traditional multi-vendor integration…
Q&A: Engineering the transition to fleet electrification
For organizations that depend on large vehicle fleets, electrification offers the potential to reduce fuel and maintenance costs while also cutting emissions. Beyond consumer electric vehicles (EVs), it requires designing charging systems capable of supporting high duty cycles, integrating with facility power infrastructure, and maintaining reliability under demanding operating conditions. And this transition is already…
Closing the gaps: precision measurement for safer, more reliable EVs
Electric vehicle (EV) engineering is defined as much by what cannot be seen as by what can. The “gaps” or unseen spaces between battery cells, slot die coating of electrode layers, cooling plates, electric motor housings, and composite joints have a significant influence on performance, safety, and durability. Managing these dimensions with high accuracy has…
Optimizing EV motor design
Electric vehicle (EV) motor design continues to evolve as manufacturers target higher power density, greater efficiency, and seamless system integration. This article reviews optimization strategies for EV motors, focusing on material innovations, control algorithms, and thermal management. It also highlights emerging testing protocols and safety standards that ensure reliable operation and support integration across next-generation…
