Abstract: An offline mutual authentication method for battery swapping includes communicating a first authentication request to a battery by a computing device associated with a battery charger. A first authentication response is communicated to the computing device. The first authentication response is verified, and a first challenge request is communicated to the battery. A first challenge response is communicated to the computing device. The first challenge response is verified, and a battery authentication status is communicated to the battery. A second authentication request is communicated to the computing device. A second authentication response is communicated to the battery. The second authentication response is verified, and a second challenge request is communicated to the computing device. A second challenge response is communicated to the battery. The second challenge response is verified, and a charger authentication status is communicated by the battery to the computing device.

Abstract: Battery swapping includes receiving a swap request for swapping a set of discharged batteries in a vehicle with a set of charged batteries at a charging station. Based on a battery swapping count provided by a user, the set of charged batteries including first and second subsets of charged batteries are selected from a plurality of charged batteries available at the charging station. At least one of a static ID or a dynamic ID is assigned to each charged battery. Each charged battery in the first and second subsets is configured as a master battery and a slave battery by integrating at least the respective static and dynamic ID in a corresponding battery management system of each charged battery, respectively, for facilitating in-vehicle battery communication. Further, the set of charged batteries is released from a charging and storing platform to a swapping platform for swapping.

Abstract: An offline authentication of batteries includes communicating an encrypted authentication request to secondary batteries and a vehicle controller by a primary battery of an electric vehicle. The encrypted authentication request is decrypted to obtain a first random number and a fleet flag. An encrypted authentication response, including a first random number, a second random number, and a vehicle identifier, is communicated to each battery. Each battery verifies the first random number and the vehicle identifier. An encrypted battery status, including the first and second random numbers and an authentication status, is communicated to the primary battery that verifies the first and second random number and the authentication status. The primary battery communicates an encrypted authentication message to the secondary batteries and the vehicle controller. The secondary batteries and the vehicle controller verify the first and second random numbers and the authentication status for authenticating each battery.

Abstract: A method for emergency response handling includes receiving an emergency signal from at least one of a vehicle or a user device of an occupant of the vehicle. Sensor data from one or more sensors in the vehicle or the user device is collected. An in-vehicle emergency is detected based on the sensor data and a severity level and a context associated with the in-vehicle emergency are determined. From a plurality of responses, one or more responses are selected, based on the determined severity level and context, for handling the in-vehicle emergency. Response actions are executed based on the selected responses. Execution of the response actions includes communicating, an instruction to at least one of the user device, an emergency contact, a response team, and user devices associated with users present within a first distance from the vehicle.

Abstract: An offline to online booking of a street-hailed vehicle by a passenger includes scanning a quick response (QR) code or a near-field communication (NFC) sticker associated with the street-hailed vehicle. Based on the scanning, QR or NFC information is retrieved from the QR code or the NFC sticker, respectively. The QR or NFC information is further processed to determine an availability of the street-hailed vehicle for allocation to the passenger. The street-hailed vehicle is further allocated to the passenger based on successful conversion of the offline to online booking of the street-hailed vehicle. A driver of the street-hailed vehicle transports the passenger from a current location to a destination location based on the allocation.

Abstract: A safety method and system for users in a vehicle is provided. The method includes operations that are executed by a circuitry of the system to facilitate safety features to the users. The operations include detecting an emergency input for activating a camera device to record real-time in-vehicle activities. A preferred contact of a user in the vehicle is determined and audiovisual information of the in-vehicle activities is communicated in real-time with each preferred contact. The recorded in-vehicle activities are further processed in real-time for detecting an emergency incident. An alert signal is generated based on the emergency incident, and one or more entities who can provide help are identified based on a location of the vehicle. The alert signal is communicated to the one or more entities along with the recorded in-vehicle activities.

Abstract: A vehicle-mounted communication system is provided. The communication system includes a communication device. The communication device includes at least a plurality of displays that are mounted on top of a vehicle. Each display includes a smoky acrylic covering for hiding one or more dead pixels. Based on real-time status of the vehicle, a driver of the vehicle, or a passenger therein, the communication device obtains targeted content and displays the targeted content on the plurality of displays for communicating relevant information to various prospective passengers for their rides or other near-by individuals who can offer help in case of any emergency.
