It comprises essential components—Motors, Batteries, Controllers, Electronic Control Units (ECUs), Microcontroller Units (MCUs), and Printed Circuit Board Assemblies (PCBAs)—each with distinct roles that collectively ensure vehicle performance. The linchpin of this intricate system is connectivity, provided through wire harnesses and connectors that facilitate power delivery and data exchange. These connections must withstand electrical, mechanical, and environmental challenges unique to each component. Below, we explore each element in detail, highlighting their functions, connectivity requirements, and how Avertronics delivers cutting-edge solutions to overcome inherent obstacles in e-mobility powertrains.
Motors are the dynamic force behind e-mobility, converting electrical energy into mechanical torque to propel vehicles forward. From brushless DC (BLDC) motors in drones to mid-drive motors in e-bikes and high-torque outboard motors in electric boats, their designs vary by application, yet all share a need for high-current wiring to manage peak loads during acceleration or heavy operation. Connectivity challenges are significant: thermal stress from sustained high currents can degrade wire insulation, leading to energy loss or failure; mechanical vibrations from terrain or flight dynamics risk loosening connections; and environmental factors, such as dust in ground vehicles or wind resistance in drones, demand robust durability.
Effective connectivity for motors relies on thick, heat-resistant cables capable of carrying currents often exceeding 50A, coupled with flexible harness designs to absorb vibrations. Electromagnetic interference (EMI) shielding is critical to prevent disruption to nearby electronics. Avertronics excels in addressing these needs with customized wire harnesses featuring high-strength insulation and modular connectors that simplify installation while ensuring stability.
