The Advanced Air Mobility (AAM) industry is transitioning from flight demonstrations to certified large‑scale operations, requiring lifecycle‑oriented, auditable power and battery testing for aircraft safety and airworthiness. This article describes six major electrical test challenges brought by high‑voltage, distributed electric propulsion systems. It presents ITECH’s modular test solutions for cells, battery packs, propulsion, avionics and charging facilities, supporting repeatable electrical validation from R&D to production of low‑altitude electric aircraft.

As AI computing clusters and high‑density data centers expand, the OCP ORV3 standard makes BBU a core part of rack power systems. Conventional single‑channel instruments cannot meet cell‑level verification requirements. This paper describes key BBU test challenges under ORV3 and introduces the ITECH IT2600 multichannel cell simulation test platform. Housed in a 1U chassis with 8 isolated channels, it delivers high‑precision source‑measure, battery and fault simulation, synchronized data logging and multi‑unit expandability, supporting cell‑level and BMS‑level validation of ORV3 BBU for R&D and production.

This paper covers BMS verification for 800‑V electric vehicles and high‑voltage energy storage using cell emulation. It introduces key test scenarios including measurement accuracy, fault detection, balancing, SOC/SOE estimation and ripple response, and outlines the ITECH hardware test platform. Relevant international automotive and EU battery standards are referenced. It stresses combining simulator bench tests with real‑battery testing to deliver repeatable and traceable BMS validation results.

ITECH IT6642C accurately simulates battery clusters at different SOC levels, supporting ZVS evaluation, CC–CP–CV switching tests, and control-algorithm validation for battery equalization converters. The application demonstrates its value in BESS research and energy storage converter development.

As offshore wind turbines grow larger, converter power modules face tougher thermal reliability requirements, making thermal-rise validation essential. Reliable testing requires stable long-duration loading and repeatable conditions, not just high current output. The IT7900 four-quadrant regenerative grid simulator provides stable power boundaries, protection and data logging to study hotspots and thermal equilibrium. This scalable platform delivers credible engineering evidence and improves test efficiency and data consistency for wind power thermal validation.
