MAIN DAY TWO | THURSDAY, 29TH SEPTEMBER, 2022

High precision current sensing through BMS is one of the key elements of a battery system to evaluate the SOC(state of charge). Moreover, precise current control is vital for cell safety and for efficient fast-charging. Therefore to measure current precisely and reliably with highest safety integrity levels based on shunt technology combined with cost efficient solutions will become more interesting for eMobility applications. This presentation gives you some insight about best-in-class shuntbased sensor solutions with an focus on:

Safety and redundancy - ASIL-D

Cost-optimized sensor design

There is a lot of buzz around Solid-State battery technology, even though they are still in an early phase of development and scaling up. The technology promises a lot from energy density improvement, thermal efficiency and stability point of view.

• What does the solid state battery landscape look like, and how far are we from integration in electric vehicles?
• What is the expected cost impact on battery cells?
• What are the opportunities and challenges in the solid-state battery value chain?
• How can solid state technology be integrated into an already existing infrastructure?
• Quantifying improvement in energy density, increase in thermal efficiency and thermal stability of the cells
• A first look at the recycling aspect of solid-state batteries

• Hybrid approach to combine High Energy with High Power cells in the same battery pack and have a modular & scalable design that fits a broad range of vehicle applications
• Goal is to increase energy and power density in the modular pack, while reducing weight and volume compared to standard solutions, and in addition allowing super-fast charging at 360kW
• Will use wireless communication and new BMS functionalities, incl multi-sensor units monitoring the various states of the battery pack, even for 2nd life applications
• In 2024 we will integrate two demo packs in a small city E V and also in a 12m full size E-Bus

So far, there are no defined standards for just BMS in the same way the industry has a defined ISO 26262 safety standards for automotive. Right now, everyone uses ISO26262 as a basis and focuses on the safety aspect of the BMS to match with the standard. Companies are trying to build systems their own way, while protecting their IP…

But there is a growing need for OEMs around the world to come together to formulate a standard for BMS as they did for functional safety. The audience will now gather together in a roundtable format to:

• Discuss what needs to be done to formulate a standardised BMS approach so there is:
• Interoperability between different chemistries
• Market standard for battery charging
• Protection of intellectual property

• Data collection including sampling rate and data compression
• Algorithms for diagnostics and prognostics running in the cloud
• Calibrate digital twins based on cloud data
• Parameter identification based on digital twin and field data
• Anomaly detection and safety improvement by data analytics and the digital twin
