摘要： A method for providing an estimated present state of charge of a battery pack includes measuring battery parameters and then calculating a first state of charge utilizing an initial state of charge and the battery parameters. An error covariance prediction is calculated for the calculated first state of charge. A correction of the first state of charge is determined by mapping the open circuit voltage of the battery to the initial state of charge to obtain an open circuit voltage-initial state of charge confidence slope, calculating a Kalman gain of the error covariance prediction, and mapping the open circuit voltage (incorporating EMF) to the first state of charge. The estimated present state of charge is calculated by correcting the first state of charge utilizing selected battery parameters, the Kalman gain, and the mapping of the resulting voltage of the battery to the first state of charge.

摘要： A modular design for a storage tank system can be deployed across multiple vehicle platforms. Certain embodiments can include a rack. The rack can be configured to hold a storage tank. The rack can include a frame assembly. The frame assembly can include a base, an upright support member, and a strap connected to the frame assembly, where the strap can be configured to secure the storage tank on the frame assembly. In some embodiments, the base includes a Y-axis support member and an X-axis support member. The storage tank can sit across the Y-axis support member in a secured configuration. The rack can be configured to removably mount to a platform of a vehicle.

摘要： A cab for a semi-truck vehicle may include a main body with a wrap around windshield providing a predetermined field of front vision and side vision. The cab may further include a seat, a rear wall, and a cabin interior accommodating a driver. The cabin interior may be located between the wrap around windshield and the rear wall and include a frontside volume and a rearside volume. A doorway formed in the main body may provide ingress to and egress from the cabin interior. A plurality of front entry steps may be disposed beneath the doorway. A door may be configured to selectively open and close the doorway, allowing direct access to the frontside volume of the cabin interior. The cab design may optimize visibility, accessibility, and interior space utilization for the driver.

摘要： Ways of making a solid-state electrolyte are provided. Various energy storage devices, such as solid-state lithium-ion batteries, may incorporate the solid-state electrolyte. The solid-state electrolyte may be manufactured by dissolving a fluoropolymer with a solvent, combining a portion of the dissolved fluoropolymer with an ionic liquid to form a PVDF-HFP/IL-Li salt solution, and combining a portion of the dissolved fluoropolymer with lithium lanthanum zirconium oxide to form a PVDF-HFP/LLZO solution. Then, coating a first side of a porous membrane with the VDF-HFP/IL-Li salt solution and coating a second side of the porous membrane with PVDF-HFP/LLZO solution to thereby form the solid-state electrolyte.
