Why did Porsche go to the trouble of designing an 800 V Taycan EV?
How higher-voltage battery packs enable faster charging ecosystems Porsche took on a considerable engineering challenge when it decided to design an 800 V EV system for the Taycan, because nearly every other hybrid and EV in the world operates at 400 V or less. There simply was not a wide range of high-voltage off-the-shelf parts… Read more »
Battery cooling performance: Comparing liquid-dispense gap fillers with thermal pads
Sponsored by LORD Corporation The focus of LORD Corporation’s study is to investigate how the superior thermal transfer provided by gap fillers versus gap pads affects cooling of actual battery modules. Battery modules were assembled using LORD gap fillers with thermal conductivity of 2 and 4 W/m·K, and also with commercially available gap pads of… Read more »
Littelfuse launches new high-speed semiconductor fuses
Circuit protection manufacturer Littelfuse has added 275 new fuses to its line of POWR-SPEED PSR high-speed fuses. The new fuses come in various sizes and amperages, and feature bolted and DIN rail mounting options. Littelfuse designed its PSR series fuses for use in power conversion and conditioning equipment for critical semiconductor devices such as diodes,… Read more »
Free eBook: Battery thermal management in hybrids & EVs
Sponsored by Elkem Thermal management is an important discussion topic in battery-powered systems when considering insulation, heat and power transfer, conduction and convection, in order to maintain the battery pack temperature within a tight tolerance to reduce thermal runaway. Thermal management of batteries in H&EVs is essential for the effective operation of motors in all… Read more »
Porsche announces base version of Taycan EV
As anticipation builds for Porsche’s upcoming Taycan EV, the company has announced a third, entry-level version. The Taycan 4S will be available with two battery sizes: the Performance Battery, with total capacity of 79.2 kWh and power of up to 522 hp (390 kW); and the Performance Battery Plus, with 93.4 kWh and 563 hp… Read more »
EuroGroup’s new gluing technology promises to improve motor efficiency and reshape electric machine design
Groundbreaking glue: New results show as much as 44% core loss reductions for the same steel and lamination thickness. Many design decisions in the EV industry are still driven by range. Engineers remain focused on delivering system efficiency improvements, because it directly translates into delivering more range without increasing the size and cost of the… Read more »
AC Fast Charging: The right fit for medium-duty EVs
What’s the largest mass transit system in the United States? Is it the public transit network? Nope. Commercial airlines? Guess again. Passenger rail? Not even close. Here’s a hint: the vehicles are colored yellow. Give up? It’s school buses, and in terms of sheer numbers this fleet is 2.5 times larger than all other forms… Read more »
South Dakota university to create international center for solid-state batteries
The South Dakota School of Mines & Technology plans to establish an international center to develop solid-state batteries. Associate Professor Alevtina Smirnova says the solid-state batteries developed at the new Center for Green Solid-State Electric Power Generation and Storage (CEPS) will be ideal for portable and medical applications, electric grids and the automotive industry. The… Read more »
