Increase in the HV creepage and clearance requirements – battery-engineers define insulative properties between voltages and determine distances needed between the components within the whole inverter design, allowing separation between parts on the PCB and the PCB tracks themselves.Careful component selection – hofer powertrain support customers throughout the entire development and implementation process in dealing with suppliers and brings the essential knowledge of the market needed to select the right set of components to assemble a system in alignment with customers’ needs.Key considerations when moving from lower voltage to 800V systems: When running at a lower current with higher voltage, there is less loss as heat, and therefore smaller, lighter cables and connectors are required. Compared to a 400V system, less current is required for an 800V inverter to transfer the same power. Meanwhile, improved performance (i.e., power) for electric powertrains can be achieved through either higher current or higher voltage. There are two main advantages in using 800V systems, improving inverter’s efficiency: faster charging as more power is transferred in less time and reduced power losses in the cabling. Our teams provide development services and technical support for individual needs through testing, simulation, technical, and concept studies to implement specific vehicle concepts. hofer powertrain has been developing its 800V systems to help its customers achieve extended range, as a new norm, with the convenient EV systems. As the infrastructure evolves, fast charging solutions such as 800V technology are gaining in speed, respectively – 800V-capable DC rapid charging infrastructure is a key enabler to extreme / ultra-fast charging XFC technology. New technologies are entering the market and help change this mindset. In recent years, car manufacturers have often been confronted by consumers' skepticism towards electric cars, wishing better solutions in charging technologies.
This charging technology promises to reduce the waiting times at the charging station drastically, but more importantly, to make range anxiety a matter of the past. This technology promises car manufacturers to gain more power into their new vehicle fleets quicker and recharge at speeds that match the fast-moving market with the soon improved infrastructures, capable of handling 800V. Growing demand for more electric vehicle efficiency, higher charging convenience with appropriate infrastructure, and reduced charging times leads many car manufacturers to explore and develop new age charging systems and technologies such as 800V inverters enabling higher efficiency and cost-effectiveness. In this part of our Electrification Weeks, we address future-oriented technologies, looking at 800V inverters and some neighboring technologies, their advantages, and their potentials in developing and implementing new-generation vehicles. We are witnessing the disruption of the automotive market by renewable energies, decreasing costs for e-batteries, alternative energy sources are becoming more appealing, and powerful storage solutions are in demand.
