Electric vehicle battery module
A system may comprise a vehicle having a frame. One or more rails may form at least a portion of the frame. The system may comprise a container configured to be mounted to the one or more rails. The system may comprise a plurality of battery packs positioned within the container below the one or more rails. Each of the plurality of battery packs may extend across an entire length of the container. The system may comprise a power distribution unit (PDU) to which the plurality of battery packs are connected. The plurality of battery packs may be configured to provide power to at least one component of the vehicle via the PDU. The container may protect against road debris and moisture.
1. A battery power system, the system comprising:
a vehicle having a frame, wherein one or more rails form at least a portion of the frame;
an enclosure configured to be mounted to the one or more rails;
a plurality of cell string battery packs positioned within the enclosure below the one or more rails, wherein each of the plurality of cell string battery packs is configured as a structural beam which extends across an entire length of the enclosure; and,
wherein the plurality of cell string battery packs are formed structural beams configured to cooperate with the enclosure to function as a monolithic block; and,
wherein the structural beams are configured to improve the resisting bending moment of the chassis in at least one of the vertical and lateral direction.
2. The battery power system of claim 1 , the system further comprising:
one or more additional cell string battery packs positioned within a container above the plurality of cell string battery packs and adjacent to the one or more rails;
wherein the plurality of cell strings battery packs are configured to form an electrical connection to at least one of an electrical component of the vehicle and a power distribution unit.
3. The battery power system of claim 1 , further comprising a layer of material connected to at least one side of the at least one of the enclosure and, the layer of material configured to protect the plurality of cell string battery packs from damage during impact.
4. The battery power system of claim 1 , wherein the battery packs of the plurality of cell string battery packs are stacked on top of each other.
5. The battery power system of claim 1 , further comprising a lid configured to cover an open top of the enclosure enclosing the plurality of cell string battery packs.
6. The battery power system of claim 1 , further comprising a plate to which the plurality of cell string battery packs are configured to be mounted, and wherein the plurality of cell string battery packs are configured to be inserted into the enclosure by lifting the plate including the mounted plurality of cell string battery packs into an open bottom of the enclosure.
7. The battery power system of claim 1 , wherein the enclosure is configured to be mounted to the one or more rails by:
affixing a portion of the container to the one or more rails; or lowering the enclosure over the one or more rails.
8. The battery power system of claim 1 , further comprising at least one component of a main driver inverter, a motor, a steering pump, an AC compressor, a DC-DC converter, a cabin heater, a cooling system, a charger, an air compressor, an accessory inverter.
9. The battery power system of claim 1 , further comprising a charging connector mounted to at least one outer wall of the container, the charging connector configured to provide power to the plurality of cell string battery packs from a power source to recharge the plurality of cell string battery packs.
10. The battery power system of claim 1 , wherein the vehicle is a truck, a van, or a trailer.
11. A method for assembling a battery power system, the method comprising:
mounting an enclosure to one or more rails, of a chassis, wherein the one or more rails form at least a portion of a frame of a vehicle;
inserting a plurality of cell string battery packs formed into structural beams within the enclosure, and wherein each of the plurality of cell string battery packs are formed into structural beams extend across an entire length of the enclosure;
wherein the structural beams across the enclosure improve the resisting bending moment of the chassis in at least one of the vertical and lateral direction; and,
wherein the enclosure protects against road debris and moisture.
12. The method of claim 11 , the method further comprising:
the plurality of cell string battery packs are configured to form an electrical connection to at least one of an electrical component of the vehicle and a power distribution unit.
13. The method of claim 11 , further comprising:
connecting a layer of material to at least one side of the enclosure, the layer of material configured to protect the plurality of cell string battery packs from damage during impact.
14. The method of claim 11 , the method further comprising at least one component of a main driver inverter, a motor, a steering pump, an AC compressor, a DC-DC converter, a cabin heater, a cooling system, a charger, an air compressor, an accessory inverter.
15. The method of claim 11 , further comprising:
mounting a charging connector to at least one outer wall of the enclosure, the charging connector configured to provide power to the plurality of cell string battery packs from a power source to recharge the plurality of cell string battery packs.
16. The method of claim 11 , wherein the vehicle is a truck, a van, or a trailer.
