Battery pack designed for second life

A European project has developed a battery prototype designed for ease of assembly and disassembly of battery components, writes Nick Flaherty. The battery pack developed as part of the MARBEL project with car maker Stellantis uses a wireless battery management system (BMS), artificial intelligence (AI) and a digital twin capable of predicting a battery’s remaining useful life, as well as its state of charge and health.

Busbar connector alternative to electroplating

Penn Engineering has developed a new technique to reduce the cost of busbar connections in electric vehicles, writes Nick Flaherty. “The challenge is how to connect busbars,” says John O’Brien, global technologist at Penn Engineering. “One of the things we have seen is a move from cabling to busbars, driven by cost. Busbars are much cheaper for the same current than cables and more suited for automated assembly, which also gives lower cost.”

Cell-to-chassis

Moving to cell-to-chassis architecture means significant changes to EV structures and materials, finds Nick Flaherty Manufacturers of electric vehicles (EVs) are placing increased emphasis on pack design optimisation. Moving from modules to packs and even to direct integration with the chassis can promote lighter weight, less space, higher energy density, and lower material and assembly costs. However, this drive toward cell-to-chassis (C2C) architecture comes with a range of engineering challenges with respect to cooling, materials and assembly processes.
