Engineers involved in battery and EV design and manufacturing have common goals: to maximize performance, lifespan, and safety.
Join this session at our Fall Virtual Conference on EV Engineering, presented by Tekscan, to learn why pressure mapping is a critical step in battery R&D for improving battery life, and how to apply it in quality control to find the “sweet spot” for battery stack pressure. Attendees will also understand how the evolution of electric and autonomous vehicles comes with the need to re-think traditional automotive R&D and design approaches, and how pressure mapping offers data and insights to inform design decisions.
Other sessions at our Fall Virtual Conference (October 17-20, 2022) include:
Pioneering Charging Technology For 800 V EVs
During this session, the Preh team will explore hit pioneering HV Booster that enables 800 V electric vehicles to charge at 400 V charging stations, in series since 2019 with Porsche Taycan.
Preh HV Booster features a resonant converter that “boosts” 400 V electrical power to 800 V allowing, with its 150 kW nominal power, the charging of 80% of the battery in just over 35 minutes. Its special topology achieves a very high efficiency (over 97%) and the in-house customized software guarantees a full interoperable use at all DC charging stations available worldwide.
Ways To Improve The Insulation Lifetime In Presence of Partial Discharges
Since the introduction of inverters for RPM control in electrical motors, the phenomenon of electrical discharges in low voltage machines gained awareness among experts.
Depending on the supply cable length, the inverter type, as well as the characteristics of used semiconductors the voltage on stator terminals, can reach a significantly higher value compared to the actual inverter output voltage.
At the same time the insulation systems for low voltage motors were never designed to withstand the presence of partial discharges in operation. In view of the latest trends towards faster switching semiconductors as well as 800V operating voltage for e-drives, the ability to handle partial discharges is becoming increasingly important. New developments in the field of insulation materials have the ability to specifically address this challenge.
Broadcast live October 17 – 20, 2022, the conference content will span the EV engineering supply chain and ecosystem, including motor and power electronics design and manufacturing, cell development, battery systems, testing, powertrains, thermal management, circuit protection, wire and cable, EMI/EMC and more.
