Free QuoteStructural batteries are changing the way electric cars are assembled. Structural adhesives are replacing screws and welds to “glue” components together using a process called adhesive bonding. This process requires additional surface preparation and creates new challenges for automakers and battery makers.
Carlstedt and Asp developed a performance analysis framework to study the benefits of using structural battery composites in EVs . Their case study manifested that the driving range could be increased by 70% for lightweight vehicles with feasible structural battery designs.
As a result, redundant structural elements can be removed, eliminating weight from other parts of the vehicle. They are said to offer “massless energy storage” because their effective weight is lower than the total weight of the cells (considering the parts they replace). Structural batteries are changing the way electric cars are assembled.
Among them, the more representative is BYD's “Blade” battery, which arranges individual battery cells together in an array, and then inserts them into the battery pack like a “blade”, which is why everyone calls it a “blade battery”.
Cell-to-chassis (CTC) designs incorporate the battery cells directly into the vehicle's chassis, optimizing space, reducing weight, and improving structural integrity. Some OMEs prefer the traditional modular setup housing 16 or 32 modules per pack, while others choose CTP designs to reduce the module count.
However, the potential gain in energy density of externally reinforced structural batteries is limited by the additional mass of reinforcement and its mechanical properties, whereas integrated multifunctional structural components inside the battery ideally do not add extra weight to it.
