BEVs work on improving inverter technology to extend cruising range
The global automotive industry is becoming increasingly electrified, but in-car battery prices remain high, contrary to initial forecasts. In addition, the cost of key components such as drive motors and inverters is also rising due to material shortages, supply chain issues, compliance with the US Inflation-Reduction Act (IRA) and tighter environmental regulations in many countries. Against this backdrop, the key to the electrification race is how to improve performance, including efficiency, while keeping BEV production costs low.
In order to extend the range of BEVs (or reduce product costs by reducing the on-board battery capacity), complete vehicles and suppliers are working on improving on-board battery technology, reducing vehicle weight, as well as improving eAxle efficiency control and inverter technology for overall energy efficiency of on-board equipment. The core of the inverter is the inverter, which is the heart of the inverter. Amongst other things, the efficient conversion of battery energy into kinetic energy is particularly remarkable, for example by switching from silicon (Si) to silicon carbide (SiC) in power module semiconductors, which are at the heart of the inverter. This has led to a clear trend towards downsizing the volume of inverters by raising their thermal performance and simplifying the cooling section. There is also a trend towards the integration of DC-DC converters, on-board battery chargers (OBC), high-voltage relays and other components into the inverter, known as ‘x in 1’. There are many technological proposals to further downsize the control unit, reduce the volume of drive systems (e.g. eAxle for BEV/FCEV, HEV/PHEV high-voltage drive systems, etc.) and improve the degree of freedom of layout and design, by reducing costs and simplifying the system through system integration.
