  • Patent number: 11912547
    Abstract: A system includes a platform to support a vehicle on a first side of the platform and a passive motion device arranged on a second side of the platform, opposite the first side, to move upon actuation. A mechanical actuator actuates the passive motion device based on movement of one or more wheels of the vehicle to change a position of the vehicle. The position of the vehicle relative to the platform is unchanged and the passive motion device is actuated by only the movement of the one or more wheels of the vehicle to change the position of the vehicle.

  • Patent number: 11914642
    Abstract: The present technology can detect potential labeling conflicts made during different labeling tasks when those tasks are checked in to ensure that a map database is free from conflicts that might interrupt publishing of a map. The present technology can determine whether a first labeled version of map portion is based on a most recent version for the map portion that is stored in the map database, and when it is determined that it is not, and there is an intervening version, the present technology can identify differences between the intervening version of the map portion and the first version of the map portion and identify differences between the second version of the map portion and the first version of the map portion. Based on the identified differences, the present technology can determine whether any of those differences are conflicting.

  • Publication number: 20240063465
    Abstract: A battery module includes first and second neighboring battery cells. The battery module also includes a cold-plate configured to remove thermal energy from the first and second battery cells. The cold-plate includes first and second sections configured to seat respective first and second cells. The first section defines a first vent arranged directly adjacent the first cell and configured to exhaust gases therefrom. The cold-plate additionally includes a first closure element arranged within and configured to block the first vent in a first mode to transfer thermal energy from the first cell to the cold-plate. The first closure element is additionally configured to open the first vent in a second mode when the first cell undergoes a thermal event to exhaust gases and transfer thermal energy from the first cell through the first vent and thereby control propagation of a thermal runaway in the battery module.

  • Publication number: 20240059170
    Abstract: A method for dynamically matching energy demand of a population of electric vehicles (EVs) with energy supply of a population of charging stations within a geofenced perimeter includes receiving, via a cloud-based server, EV information from each respective EV, and receiving charging station information from each respective charging station. The method includes generating an SoC map and a charging station power map from the EV information and the charging station information, respectively, and predicting the energy supply and demand using the maps. The server dynamically matches the EVs to at least one of the charging stations or vice versa using a reward function, the predicted energy supply, and the predicted energy demand, including generating a rank-ordered listing for each of the EVs and/or each of the charging stations in a manner that maximizes an expected discounted future reward.
