15-minute rapid charging for

any EV with our e^pack

Scalable and



Highest energy throughput in the lowest space guaranteed. Kills the need for large, show charging hubs

Our proprietary connector, capable of handling 600A of current

Connects the e^pump to the e^pack


Off-board Thermal

Management System

While charging, our e^pump cools the e^pack by pumping refrigerated water through the e^plug.


15-minute rapid charging generates 256x more heat

Than 4 hour slow charging

Conventionally, extracting this heat needs bulky & expensive cooling systems on the vehicle. But, why lug around and pay for a system that you only need while charging?

Hence, we offboarded the system onto the e^pump to make all EVs powered by us lighter and more affordable.
