PHOTOS: Maxwell Visits Mainz, Germany for AABC Europe 2016

I attended the AABC conference in Mainz, Germany with several of my colleagues, and as a first time attendee, I was impressed by the level of participation from academia and industry. Poster sessions were held every day of the conference and provided a good opportunity to engage in discussions with the presenters. We also had a chance to catch up with current and potential customers. Maxwell was a silver sponsor of the conference.
I expected the show to be battery centric. I was pleasantly surprised that the conference covered varied topics. A few of the salient sessions are listed below.
- Electrochemical Capacitors: This was an all-day electrochemical (EC) capacitor session where new (materials) research activities were presented by academicians and chemical/materials industrial researchers. Maxwell’s vice president of strategy, marketing and business development, Chris Humphrey, chaired the session and panel discussion on new EC capacitor products.
- Battery Engineering: This session included discussions around battery integration methodologies, i.e. energy storage pack design and integration, thermal engineering challenges, and advances in pack design to improve thermal management and product reliability. Although pertaining to batteries, these pack design evaluations can be adopted across all energy systems, including ultracapacitors.
- xEV and Industrial Battery Market: Battery requirements vary with applications, offering openings for multiple technologies. In this session, presentations included eEV market assessment and future projections for the development of hybrid and electric vehicles, prospects for advanced batteries and competing technologies, and technological and commercial challenges. This session was very informative since it included the growth of the China bus market and provided insight on the projected growth of EV buses and hybrid buses; a platform where Maxwell ultracapacitors are used extensively.
- High voltage and xEV Battery Technology: An informative overview of lithium-ion technology which is the predominant battery technology used for plug-in hybrids and all-electric vehicles. Cell chemistry and mechanical design vary among developers as they try to balance safety, durability, performance, and cost to improve the value proposition of the technology. In this session, EV/PHEV/HEV vehicle and battery developers discussed battery designs and performance data. This session also included an overview of automotive battery systems, materials and cost breakdown, and projected cost erosion over the next five years.
- Energy Storage for Low Voltage Hybrids: Energy storage solutions for both 12V and 48V architectures were discussed during this session. PSA presented an overview of energy storage solutions for 14V systems outlining the potential advantages of using ultracapacitor/battery hybrid systems. Eberspächer presented "Supercap-based storage systems for high power transient loads" where the advantages of ultracapacitor technology were outlined, namely, low ESR, operation over wide temperature range and long life.
- It is interesting to note that ultracapacitors are now included, with other battery chemistries, as an energy storage solution option.
- Increasing electrification on automotive platforms has resulted in higher transient power loads which have a detrimental impact on batteries, however a perfect application for ultracapacitors.
The conference was a great opportunity to learn about the state-of-the-art energy storage systems and their use in low and high voltage automotive and industrial vehicle platforms. Maxwell must continue to educate the industry on the advantages of using ultracapacitors alone, or in conjunction with batteries, to address transportation performance needs.
