Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A module comprises a tubular enclosure attached (e.g., glued) to different surfaces of the cells and forming two fluid channels with one side of the cells and two additional fluid channels with the opposite side. The module also comprises a first end plate, which is attached to the tubular enclosure and comprises two electrical terminals for connecting to an electric vehicle (EV) and/or external charger. The first end plate also comprises a first fluidic port (fluidically coupled with two fluid channels) and a second fluidic port (fluidically coupled to the remaining two fluid channels), both are configured to form fluidic coupling to the electric vehicle and/or the external charger. The module also comprises a second end plate that fluidically interconnects paid fluid channels from different cell sides.

In a training phase, training data may be used to train a supervised machine learning prediction model and an unsupervised machine learning segmentation model. Then, in a testing phase, the supervised machine learning prediction model may be used to predict a target outcome for a test data observation. Also, the unsupervised machine learning segmentation model may be used to evaluate the novelty of the test data observation relative to the training data.

Described herein are battery modules comprising immersion-cooled prismatic battery cells and methods of fabricating thereof. A battery module comprises prismatic battery cells that are stacked along the primary module axis. The module also comprises top, bottom, and side covers and two end plates, collectively enclosing these battery cells. Each cover forms two fluid channels, both fluidically open to the prismatic battery cells. Furthermore, the module comprises bus bars that interconnect the cell terminals and protrude into the fluid channels formed by the top cover. One end plate comprises two fluid ports for connecting to a thermal management system. Each port is fluidically coupled to one fluid channel, formed by the top cover, and one fluid channel, formed by the bottom cover. The other end plate fluidically couples the two fluid channels, formed by the top cover, and, separately, the two fluid channels, formed by the bottom cover.

A foldable non-highway electric vehicle (EV) for recreational use. The non-highway EV may include a chassis and a foldable battery module coupled to the chassis. The foldable battery module may fold to a position to allow portable transport of the non-highway EV. Suspension may control movement of the wheels relative to the chassis. The suspension may also be set in a plurality of different configurations, including a configuration where the suspension is set in a transport position. With the battery folded and the suspension set in the transport position, the footprint of the non-highway EV may be significantly reduced, to allow for convenient transportation of the non-highway EV.

Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A method comprises positioning a swappable battery module on a battery dock comprising dock fluidic ports and sliding the swappable battery module to the dock fluidic ports until these dock's ports are fluidically coupled with the module's fluidic ports. Specifically, the dock comprises an enclosure and a module support rail slidably coupling the swappable battery module and the enclosure. The module support rail comprises a rail base, a first slider, a second slider, and a lever-based unit, interconnecting the rail base and both sliders. The rail base is fixed to the enclosure, while the second slider is detachably coupled to the module. The two sliders move at different speeds or at the same speed relative to the dock base depending on the proximity of the first end plate to the dock base.

Described herein are DC-DC converters with a ratio of the power output to volume of at least 2 kW per liter or even at least 4 kW per liter. Such DC-DC converters can operate at power levels of at least 150 kW or even at least 200 kW. A DC-DC converter comprises an enclosure and a front plate sealed against the enclosure using a set of fasteners. The DC-DC converter also comprises a converter unit comprising a switching sub-module, a diode sub-module, and an inductor as well as an additional converter unit comprising an additional switching sub-module, an additional diode sub-module, and an additional inductor. The switching sub-module and the additional switching sub-module or, more generally, the converter unit and the additional converter unit are configured to operate out of phase. The inductors are immersed cooled, the switching sub-modules are conductively cooled, while the diode sub-modules are convectively cooled.

Described herein are methods and systems for obtaining high-quality images, which may be suitable for various applications such as training and operating artificial intelligence (AI) systems. Specifically, a system may comprise multiple cameras and one or more actuators that are capable of moving these cameras relative to each other. For example, these cameras may form one or more stereo pairs, each pair having its stereo axis. The actuators can change baselines in these pairs and/or tilt these stereo axes relative to the imaged objects to address possible self-similarity issues associated with the shape of these objects and their orientation relative to the cameras. In some examples, the simultaneous images captured by these cameras are used to construct a three-dimensional (3D) model. The fidelity of this model is then used to determine the position of the cameras (as a camera unit or individually for each camera).

Low-noise electric lawnmowers comprise curved cutting blades. In some examples, a lawnmower comprises a driving unit and a mowing unit with a mowing-unit deck. The mowing-unit deck comprises a set of blade units (e.g., 3 units) and a discharge conduit. Each blade unit comprises a blade enclosure and a cutting blade with a cutting edge having a curved shape. For example, the cutting edge, at a point furthest away from the blade center axis, may form an approach angle of greater than 90° but be less than 90° closer to the blade center. This curving aspect allows operating the blade at lower rotating speeds (e.g., less than 3,000 RPM), which reduces the turbulence and noise. In some examples, the blade enclosure forms an enclosure tunnel such that the tunnel's cross-sectional area increases from the tunnel's inlet to the outlet.

Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A method comprises positioning a swappable battery module on an external charger comprising charger fluidic ports and sliding the swappable battery module to the charger fluidic ports until these charger's ports are fluidically coupled with the module's fluidic ports. Specifically, the external charger comprises an enclosure and a module support rail slidably coupling the swappable battery module and the enclosure. The module support rail comprises a rail base, a first slider, a second slider, and a lever-based unit, interconnecting the rail base and both sliders. The rail base is fixed to the enclosure, while the second slider is detachably coupled to the module. The two sliders move at different speeds or at the same speed relative to the charger base depending on proximity of the first end plate to the charger base.
