If we view this also in the context of time-to-market (and total cost of ownership), the right (bi-directional) power supply can play a role by being scalable not just in power, but also in interaction: that is, reusing tests and programming effort while transitioning from development to prototypes, and from prototypes to production.
At the end of the life cycle, after being used in E-Mobility, degraded batteries may have a second life in domestic or grid-coupled storage – but they need to be thoroughly qualified. Bi-directional power supplies can help, again, in achieving this – or in deep discharging batteries and fuel cells for recycling.
In episode 7 of the PCIM Podcast, Michael Himmels, Head of Product Management at EA Elektro-Automatik, talks about the role of power supplies, and how they continue to rise to emerging challenges.
