  • Patent number: 10741888
    Abstract: Embodiments of the present invention include a battery management system that provide a plurality of channels that allow communication between host and clients. This communication may operate in bi-directional modes such that commands from the host and responses from the clients are transmitted clockwise or counter-clockwise around a daisy-chain loop. This architecture provides both a high level of redundancy across multiple channels as well as transmission directions around the loop. The use of multiple channels provides a separation in signal paths akin to the provision of completely separate physical wires, preventing malfunction of spurious operation of devices using one channel from interfering with the normal operation of devices using the other channel. In addition, the signaling architecture allows a host to dynamically transmit commands and receive responses between specific client(s) and host or broadcast communication across all clients.

  • Patent number: 10714735
    Abstract: A battery pack includes an enclosure containing a plurality of battery modules. A cooling system disposed among and electrically isolated from the plurality of battery modules uses a coolant solution that is a first mixture of a first liquid and a second liquid in a predetermined ratio to produce a first boiling point. Boiling of the coolant solution changes the predetermined ratio to produce a second boiling point that is higher than the first boiling point and that is sufficient to induce a thermal runaway condition for the plurality of battery module. A sensor monitors at least one operational characteristic of the plurality of battery modules and a controller determines a possible high voltage electrolysis within the enclosure based upon the at least one operational characteristic. A remediation system is responsive to the possible high voltage electrolysis to decrease risks associated with the possible high voltage electrolysis when operated.

  • Patent number: 10678244
    Abstract: An autonomous control system generates synthetic data that reflect simulated environments. Specifically, the synthetic data is a representation of sensor data of the simulated environment from the perspective of one or more sensors. The system generates synthetic data by introducing one or more simulated modifications to sensor data captured by the sensors or by simulating the sensor data for a virtual environment. The autonomous control system uses the synthetic data to train computer models for various detection and control algorithms. In general, this allows autonomous control systems to augment training data to improve performance of computer models, simulate scenarios that are not included in existing training data, and/or train computer models that remove unwanted effects or occlusions from sensor data of the environment.

  • Patent number: 10587162
    Abstract: An electric motor includes a case, a stator that includes end-windings, a rotor coupled to the case via at least one rotor bearing, at least one drive motor fluid pump, and drive motor electronics. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion, a fluid feed tube having a fluid receive end and a fluid feed end, the fluid feed end extending into the hollow cylindrical body, and a plurality of fluid exit ports. The drive motor electronics power the stator with or without causing rotation of the rotor. The drive motor fluid pump pumps fluid into the hollow cylindrical body via the fluid feed tube, pumps the fluid out of the plurality of fluid ports, and onto the stator end-windings to collect heat from the rotor and the stator. The heated fluid may be used for heating a battery.
