HEAR OEM PLANS FOR MAKING BETTER BATTERY PACKS THAT ARE MORE EFFICIENT, DESIGNED TO RESIST THERMAL RUNAWAY AND DELIVER HIGH PERFORMANCE

ARRIVAL's Charging System Product Lead, Ekaterina Sergeeva, who is an expert in advanced battery management system (BMS) algorithms design and functional safety (FuSa) concept development for various electric vehicle (EV) architectures, has written a featured article for Automotive IQ that is available for you to download.

In her article, Ekaterina discusses the strategy of reusing EV battery modules for mechanical and software development for the EV fleet. As battery packs are a major cost driver in EVs, there is a significant focus on approaches to reduce their price in the long term. Recycling aged battery modules could be an alternative approach to reducing costs, as they can be recovered and returned to the first stage of cell and module production.

Ekaterina's article explores the challenges associated with unifying recycling systems for different cell chemistries and suggests that repurposing aged battery modules for stationary applications such as energy storage systems could provide several benefits. These benefits include better returns on investment for EV fleet companies, reduced need for new battery production, reduced initial investments, and less landfill waste. The article also discusses the certification requirements that repurposed or reused battery modules need to meet for stationary applications.

The battle for the battery of the future continues to gain in intensity, with lithium-ion remaining the technology of choice as the latest developments could ensure it remains the default for years to come. On the other hand, new materials, whether for anodes or cathodes, are heading toward improvements on the atomic level. Would you like to further explore this topic?

Together with environmental concerns, the introduction of Li-ion chemistries in automotive batteries has driven the beginning of a vehicle electrification wave over the past 10 years. During the coming decade, battery electric vehicles (BEVs) will have to become commonplace and start yielding profit for original equipment manufacturers (OEMs).

To achieve this, battery and vehicle manufacturers will have to further mitigate the current gaps compared to internal combustion engine (ICE) driven cars. These include cost, range, charging speed, reliability and safety.
