Portable and modular energy storage with authentication protections for electric vehicles
First Claim
1. A power system that authenticates multiple battery packs to allow for power transfer between the battery packs and an external load system, the power system comprising:
- a plurality of modular battery packs, wherein each of the plurality of modular battery packs comprises;
a first housing;
a plurality of battery sub-systems, wherein each of the plurality of battery sub-systems comprises;
a plurality of individual battery cells;
a processor; and
a memory that stores a serial number for the battery sub-system;
a power sub-system that;
authenticates, and receives the serial numbers from, the memories from each of the plurality of battery sub-systems; and
aggregates power from the plurality of battery sub-systems;
a first interface for authentication communication; and
a second interface that transmits power from the power sub-system;
a second housing configured to removably receive the plurality of modular battery packs; and
a processing system that is configured to exchange authentication information with the plurality of modular battery packs through the respective first interfaces, wherein the respective second interfaces are only enabled to transmit power when the authentication information is validated.
