]]>The use and storage of renewable energies is also finding increasing application in private and commercial environments: stationary home battery storage systems based on Li-ion battery technology are a market with a great future. BMZ GmbH, a leading system supplier for lithium-ion batteries, develops such battery home storage devices, which are also marketed under its own name as the EES 7.0, EES 9.0 and ESS X storage series. This means that the regenerative solar power generated in photovoltaic systems can be used in private and commercial applications more independently of the time of day and the position of the sun.

AV supports the various BMZ battery projects with material selection, during plastic-compatible component design and with CAE-based component simulations to meet the requirements of the UN Transport Test for Batteries (UN 38.3). Further services include moldflow analyses and technical injection molding support.

"Every battery project is technically demanding, which is why I am all the more pleased that plastics from AV can make an important contribution here," explains Jens Ufermann from AV, who looks after BMZ GmbH locally, adding: "Together with customers like BMZ, we are working on sustainable product and application developments to master the challenges of future battery technologies."

High requirements for stationary and mobile applications

Similar to battery systems for mobile applications such as cars, buses, scooters and pedelecs, energy density and safety are important aspects in the development of battery products for stationary use, as is the case with BMZ GmbH's energy storage systems.

"Our in-depth understanding of the diverse applications of battery systems and our many years of experience in materials for battery applications enable us to provide our customers with both technical expertise and suitable products," says Dr. Julian Marschewski, Market Development Manager in Electric Vehicle Battery Packaging.

Polycarbonate blends with tailored properties

Bayblend® (PC+ABS) blends from AV play an important role in both mobile and stationary battery applications, for example in placing individual cylindrical battery cells in 18650 or 21700 format in a cell holder. To achieve this, the material must have excellent mechanical properties, above all high impact strength, but also high flowability in order to achieve the thinnest possible walls between the individual battery cells when manufacturing the cell holders through injection molding.

Additional safety in later use is provided by the incorporation of flame retardant grades that meet the high flame retardancy standards of Underwriters Laboratories according to category UL 94 V-0.

Broad range of products

The AV portfolio for battery applications continues to evolve. For cell holders for holding cylindrical battery cells, pouch cell frames, battery housings and similar applications the focus is on both unfilled (, ) and mineral-filled (, ) along with glass-fiber-reinforced () flame retardant Bayblend® products. AV also offers thermally conductive polycarbonate grades of the Makrolon® TC product family that can contribute to battery thermal management.

]]>The automotive industry is in a state of upheaval worldwide. Alternative drive technologies, new forms of connectivity and autonomous driving necessitate completely new vehicle concepts. One of AV's current focal points is the use of polycarbonate plastics in electric vehicles. 

The heart of future electric cars and hybrid vehicles is a lithium-ion battery. In order to position a large number of battery cells precisely and in a small space, cell holders and frames as well as housing components must be very dimensionally stable and mechanically robust. Depending on the design principle of the battery pack, the material must also be flame-retardant and meet category V-0 of Underwriters Laboratories' UL94 flammability classification even at low wall thicknesses down to 0.75 millimeters. 

High-performance plastic solutions for battery housings
AV has many years of experience in encapsulating lithium-ion batteries for laptops and other electronic devices. To achieve this, the company has developed various polycarbonate blends that meet these requirements and are also extremely impact-resistant over a wide temperature range – especially at sub-zero temperatures. At the Fakuma 2018 trade fair, the company will present various battery modules, cell holders, crash absorbers and other products at its stand number 4206 in Hall B4.

“When it comes to cell holders and the integration of battery cells into modules, flame protection is particularly important.” explains Dr. Julian Marschewski from AV. The electric mobility expert adds: “The properties of the materials used in the battery environment play a decisive role in passing the many functional and safety tests on the finished component and contribute to the battery's safe operation over its entire life cycle." 

Tailor-made materials
A flame-retardant polycarbonate ABS (acrylonitrile-butadiene-styrene) blend of the Bayblend® FR type is ideal for cell holders and battery modules. It is temperature-resistant and dimensionally stable, and the parts can be produced efficiently with injection molding. The plastic is also used in mobile GreenPack rechargeable batteries from the Berlin-based manufacturer of the same name. 

The crash absorber exhibited at Fakuma 2018 is made of the PC-PBT (polybutylene-terephthalate) Makroblend® KU-2 7912/4. The material has very high impact strength and particularly high ductility at low temperatures. The honeycomb structure contributes to the extreme impact resistance of the crash absorber. 

Another special material is the highly filled polycarbonates of the Makrolon® TC product family, which are already used for heat sinks in LED lamps, for example. These products are thermally conductive but also available as electrically insulating versions so they can contribute to the efficient thermal management of batteries.

Battery pack for tough conditions
Enduros have to be ready for all wind and weather conditions, but above all must withstand the toughest mechanical demands. In these off-road motorcycles, too, the trend is towards electric drive. Californian electric bike specialist Alta Motors is a leading manufacturer of such machines. The battery under the name Alta Pack is equipped with a jacket made of the extremely impact-resistant PC-PBT blend Makroblend®. 

AV continues to drive the safe integration of lithium-ion cells in the traction battery of electric vehicles forward. Next year, the company plans to actively participate in leading industry events such as the Battery Show from 5 to 7 May in Stuttgart and the Battery Experts Forum from 10 to 12 April in Frankfurt am Main.
