The challenge of range anxiety from DC fast-charging incompatibility
Charge anxiety is on the rise as today’s EV primary battery voltages increase from 400V to 800V, even though public infrastructure is not adequate to support 800V DC fast charging. Upgrading charging stations is not a tenable short-term solution. A faster, more holistic approach is an onboard conversion solution that enables compatibility between 400V and 800V EV batteries and roadside charging stations. With Vicor scalable, bidirectional, high-density power modules, this approach can be adopted quickly, with minimal investment and far easier execution.
The Power Delivery Network
The NBM9280 provides 37.5kW of 400V and 800V fixed-ratio conversion in a 92 x 80mm CM-ChiP package, enabling a high-efficiency and high-density scalable onboard solution for compatibility between EV batteries and roadside DC fast-charging stations. The bidirectional capability of the NBM9280 allows the same module to be used for either step-up or step-down conversion. The NBM9280 can also provide a 400V source for air conditioning and cabin electronics during 800V charging, minimizing battery balancing circuitry.

Tesla commits to 48-Volt automotive electrics
48V is soon to be the new 12V according to Tesla. Size and weight reduction and enhanced power efficiency are a few of the benefits.
High-bandwidth power modules quell the disruption of high-voltage line ripple rejection
Vicor DC-DC converters combine high bandwidths with soft switching topologies to reduce EV ripple rejection more effectively than conventional solutions
BEVs have a weight problem that can’t be solved with traditional approaches
BEVs are getting heavier and adopting a 48V zonal architecture curbs the weight. High-density power modules maximize weight reduction and efficiency.
