In the age of electrification, is the 12V battery still necessary?
Today’s BEVs are powered by 400 or 800V batteries. So is a 12V battery still needed? Learn how small, power modules can replace the 12V battery.
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 NBM6123 provides 6kW of 400V and 800V fixed-ratio conversion in a 61 x 23mm 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 NBM6123 allows the same module to be used for either step-up or step-down conversion. The NBM6123 can also provide a 400V source for air conditioning and cabin electronics during 800V charging, minimizing battery balancing circuitry.
