Abstract

A power system is enclosed, which may comprise one or more modular and exchangeable battery packs; at least one of the battery packs comprising one or more individual electrochemical cells, a housing, and a first blind electrical connector; one or more connection buses; and at least one of the connection buses comprising a plurality of second blind electrical connectors disposed to self align with the first blind electrical connectors of the battery packs.

Claims

1. A power system, comprising:

one or more modular and exchangeable battery packs;

at least one of the battery packs comprising one or more individual electrochemical cells, a housing, and a first blind electrical connector;

one or more connection buses; and

at least one of the connection buses comprising a plurality of second blind electrical connectors disposed to self align with the first blind electrical connectors of the battery packs.

2. The power system of claim 1, wherein the individual electrochemical cells are arranged in series to produce voltage.

3. The power system of claim 1, wherein the individual electrochemical cells are arranged in parallel to produce voltage.

4. The power system of claim 1, wherein the first blind electrical connector of the battery back is off centered to allow the battery pack to be self aligned with the second blind electrical connector of the bus in only one direction to assure correct polarity.

5. The power system of claim 1, wherein the first and second electrical connectors have a male-female self aligning configuration.

6. The power system of claim 1, wherein each of the battery packs comprise a length of 27 inches, a width of 11 1/16 inches, and a height of 6 inches.

7. The power system of claim 1, wherein each battery pack produces 156 volts.

8. An electric vehicle, comprising:

one or more electric motors for propulsion of the electric vehicle;

one or more hollow cavities for enclosing one or more modular and exchangeable battery packs;

at least of the battery packs comprising one or more individual electrochemical cells, a housing, and a first blind electrical connector;

wherein the one or more cavities are configured in the electric vehicle to distribute weight of the one or more battery packs;

one or more connection buses; and

at least one of the connection buses comprising a plurality of second blind electrical connectors disposed to self align with the first blind electrical connectors of the battery packs.

9. The electric vehicle of claim 8, wherein battery chemistry of the individual electrochemical cells is selected from the group consisting of nickel metal hydride, lithium ion, and lithium iron phosphate.

10. The electric vehicle of claim 8, wherein the housing of the battery packs comprise a standard shape and size.

11. The electric vehicle of claim 8, wherein the battery packs are configured to be exchangeable by hand.
