Expanded Abilities or Enhanced Capacities
In the ever-evolving electric vehicle (EV) sector, companies are continuously innovating to overcome challenges and offer a seamless EV experience. Two crucial trends driving change are battery charging and electric machines.
Wide Bandgap (WBG) Semiconductor: WBG materials, such as silicon carbide (SiC) and gallium nitride (GaN), boast superior electrical properties. These semiconductors promise improvements in efficiency, reliability, and performance for EV applications. Incorporating SiC and GaN devices into on-board chargers (OBCs) and DC-DC converters results in faster charging, higher efficiency, and reduced energy loss compared to traditional silicon-based semiconductors. Furthermore, WBG-based traction inverters convert DC battery power to AC for the electric motor, enhancing vehicle efficiency and reducing heat generation for extended driving ranges and better battery performance.
Electric Machines: The preference for enhancing power density and efficiency leads to groundbreaking designs, improvements to fundamental machine topologies, and new machine classes, revolutionizing the EV industry. Traditional traction drive systems are now leaning towards using permanent magnet machines. However, the industry is witnessing a shift towards non-rare-earth machine alternatives, such as synchronous reluctance machines (SynRM). This trend aims to reduce costs by minimizing reliance on rare-earth materials and offer low-cost machines. Alternatively, machine and power electronics integration for compactness, cost savings, and decreased electromagnetic interference is an ongoing focus.

Battery Charging System Solutions:
- Shift to Wide Bandgap (WBG) Semiconductors: Silicon carbide (SiC) and gallium nitride (GaN) devices outperform traditional semiconductors by providing improved efficiency, switching frequencies, and operating temperatures. WBG devices allow for faster charging and extended battery life, contributing to increased driving range per charge.
Battery Cooling Technology Solutions:
- Phase Change Material-Based Cooling: Phase Change Materials (PCMs) absorb and release heat energy during the solid-to-liquid and liquid-to-solid phase transitions, respectively. Companies like AllCell Technology and Advanced Cooling Technologies Inc are pioneering PCM-based cooling solutions to address thermal management challenges in EVs.
- Heat-Pipe Based Cooling: Heat pipes facilitate the transfer of heat energy from the battery, while PCMs act as heat sinks during operation for stable performance and extended battery life. Companies such as Allatherm are harnessing this technology for improved thermal management in EV charging stations.
- Thermoelectric Element-based Cooling: Thermoelectric coolers employ semiconductors between heat sources and sinks to produce an electric voltage, which generates a temperature difference for heat transfer. This approach provides precise temperature control, but manufacturers like 3M and Ferrotec are working on enhancing its efficiency and power density.
In conclusion, competition within the EV sector is fierce, with new players, acquisitions, and constant innovation on the horizon.
