6. The hydraulic fracturing system of claim 1 , wherein the one or more battery trailers have an output power of between 3 MW and 8 MW.
7. The hydraulic fracturing system of claim 1 , further comprising:
a battery monitoring system to monitor at least one of a battery health or a battery charge level of the one or more batteries.
8. The hydraulic fracturing system of claim 3 , wherein the at least one fracturing support component comprises at least one of an electric powered blender or a data van.
9. The hydraulic fracturing system of claim 4 , wherein the alternative power supply is at least one of a mobile generator, a mobile substation, a utility grid, or a secondary battery trailer.
10. A hydraulic fracturing system, comprising:
one or more battery trailers arranged at a well site where hydraulic fracturing is to be performed, the one or more battery trailers each including one or more batteries to store and provide an operational energy at the well site;
a plurality of hydraulic fracturing components to receive the operational energy from at least the one or more battery trailers, at least some of the plurality of hydraulic fracturing components comprising one or more transformers; and
a switchgear system positioned electrically between the one or more battery trailers and at least some of the plurality of hydraulic fracturing components.
11. The hydraulic fracturing system of claim 10 , wherein the one or more battery trailers have a storage capacity between approximately 1 MW hour and 4 MW hours.
12. The hydraulic fracturing system of claim 10 , wherein the one or more battery trailers have an output power of between 3MW and 8MW.
13. The hydraulic fracturing system of claim 10 , wherein the operational energy from the one or more battery trailers is transmitted as alternating current (AC) power.
14. The hydraulic fracturing system of claim 10 , further comprising:
a utility grid connection; and
a mobile substation electrically positioned between the utility grid connection and the one or more battery trailers;
wherein energy received from the utility grid is conditioned and transmitted to the one or more battery trailers to charge the one or more batteries.
15. The hydraulic fracturing system of claim 10 , wherein the one or more battery trailers are operational in at least one of a pass through mode, a standby mode, a power supply mode, or a charge mode.
16. The hydraulic fracturing system of claim 14 , wherein the mobile substation is further coupled to at least some of the plurality of hydraulic fracturing components to provide the operational energy to at least some of the plurality of hydraulic fracturing components, via the switchgear system, independent from the one or more battery trailers.
17. A method, comprising:
positioning one or more dedicated battery trailers having one or more batteries to provide an operational energy to hydraulic fracturing equipment at a charging location, the charging location including at least one of a hydraulic fracturing site or an equipment staging location off-site from the hydraulic fracturing site; and
causing an electrical energy to be transmitted to the one or more batteries to increase a charge of the one or more batteries, the electrical energy being provided from one or more of a utility power source or an on-site power generator.
18. The method of claim 17 , wherein the electrical energy is transmitted to the one or more batteries while the one or more batteries provide the operational energy to the one or more connected components.
19. The method of claim 17 , wherein the on-site power generator is at least one of a diesel generator, a gas engine, a gas turbine, or a mobile power station coupled to a utility connection.
20. The method of claim 17 , further comprising:
causing electrical energy to be transmitted to the hydraulic fracturing equipment from one or more of the utility power source or the on-site power generator.
