Covestro Polycarbonate Power Assisted Electric Vehicle Battery Frame and Holder

Electric vehicles not only help reduce emissions, they can also be f.

A racing traction battery is extremely demanding in design, as it is one of the most important components in a race, determining whether a racer has enough power to win over competito.

Since the 2018 season, Covestro has supplied the.

At its pilot plant in Leverkusen, operators extrude sheets from Bayblend®, a PC + ABS blend, for the production of frames and supports for battery modul.

Flame Retardant Materials for Safety Batteries

In the battery design department, various disciplines of the Esslingen University of Applied Sciences collaborate with each other, from electrical engineering, to electronics and mechanical engineeri.

In addition, Formula Student has in its rules and regulations clear instructions and provisions for certain design requirements for students, including the safety of handling lithium-ion batteri.

In addition to active monitoring and control of batteries, the Formula Student Regulations explicitly require that flame retardant materials comply with the Underwriters Laboratories' flame retardant standards, which fall under the UL 94 V-0 category in the General Technical Requiremen.

“We are delighted to once again support the 2019 event with polycarbonate hybrid panels from Covestro, which allow us to process them with ease,” explains Raphael Raff, who is currently in charge of the high-voltage submodule project at.

This year, the racing team, in conjunction with Covestro's Bayblend® product experts, opted for a PC + ABS blend with a density reduction of about 10%, which allows for a reduction in the weight of the race car while maintaining excellent mechanical, electrical and thermal properti.

The upper part of the traction battery features a white frame part made of a PC + ABS polycarbonate blend from Covestro's Bayblend® flame retardant produ.

Suitable for large car series

For large-scale vehicle production, designers are looking for materials that meet the stringent requirements of automakers for vehicle operation while being easy to proce.

Compared to semi-crystalline materials, amorphous plastics like polycarbonate offer the following advantages: no shrinkage during injection molding, and very low water absorption, which facilitates the design of thin-walled, distortion-free componen.

At the same time, polycarbonate also has excellent flame retardant properti.

Continuous development of battery application portfolio

Covestro continues to develop a product portfolio for various battery applicatio.

Covestro also offers the Makrolon® TC product range in thermally conductive polycarbonate grades for battery thermal manageme.
