This paper provides an overview of the different types of traction battery mounting arrangements available in electric buses globally. The paper describes a key comparison of all the types of traction battery mounting strategies used in EV buses along with their dominance and limitations. In EV buses, bigger sized batteries are used which directly affect vehicle architecture, assembly & serviceability. On the other hand, larger-sized batteries are used in buses which carries heavy mass, which influences vehicle dynamics & performance characteristics such as vehicle ride, handling, braking & NVH. The most important consideration in EV vehicles is safety, which comes in first place, so this paper gives some ideas to carefully design battery mounting arrangements for EV bus applications. There has been seen a very positive adaptation of EV buses in the last few years due to the rise in Co2 and global warming. Many EV bus manufacturers have entered the market with their innovative ideas of traction battery mounting arrangements. Day to day, we are witnessing a great evolution in EV buses in terms of design, performance and safety. The electric bus architecture is directly driven by the traction battery mounting strategy, because in EV's traction batteries occupy maximum space compared to other vehicle components, that's why care needs to be taken while positioning and mounting of traction batteries. So a comprehensive report is prepared on traction battery mounting arrangement in EV Buses based on study of different EV bus manufacturers globally.
