Systems and Methods for Preparing an Electric Vehicle for Travel
20230194271 · 2023-06-22 · ·

A user may specify via a user device an origin, a destination, a date of arrival and a time of arrival at a destination. A server may determine a route from the origin to the destination, the amount of time for travel from the origin to the destination and time for departure. The server may also determine whether the battery should be charged prior to departure and if it does, the server may control the charging process. Time for departure and charging may be reported to the user. Message may be sent to ask the user to connect the electric vehicle to the charger.

Temperature regulation system and method for estimating foreign matter clogging amount

A temperature regulation system includes: an electric storage device, installed in a vehicle and configured to perform charge and discharge; an intake duct that leads air of a vehicle interior to the electric storage device; a fan configured to cause the air to be taken into the intake duct; a filter that is provided inside the intake duct and that prevents passage of foreign matter; and a controller that estimates a clogging amount of the foreign matter on the filter. The controller is configured to increase the estimated clogging amount as there increases a total amount of the air that is supplied to the electric storage device accompanying driving of the fan, and the number of times that the vehicle is brought to a state in which air is allowed to flow into and flow out of the vehicle.

Battery thermal management systems for providing improved battery cooling as a function of vehicle speed

Thermal management systems are provided for thermally managing electrified vehicle battery packs. An exemplary battery thermal management system may monitor the availability and effectiveness of a radiator for thermally managing a battery pack. A control unit may be configured to actuate a valve from an open position to a closed position that prevents the flow of the coolant to the radiator when a coolant temperature of the coolant is less than a modified ambient temperature. The modified ambient temperature may be derived as a function of a vehicle speed.

20170353039 · 2017-12-07 ·

Present invention concerns charging of a power source of a device. A power usage pattern collector is configured to: collect data on power usage in a device, power source of which is chargeable, with regard to at least one particular criterion having influence on power usage in the device; and determine at least one power usage pattern by use of the collected data, said power usage pattern specifying power usage in the device with regard to at least one particular reoccurring criterion. A charging controller is configured to: acquire at least one power usage pattern; and control charging of a power source of a device by use of the at least one acquired power usage pattern. Present invention relates also to corresponding methods, correspondingly arranged computer program products, correspondingly arranged computer-readable recording media, and a system comprising the power usage pattern collector and the charging controller.

Diagnosis method of battery, diagnosis device of battery, diagnosis system of battery, battery-mounted device, and non-transitory storage medium

According to an embodiment, a diagnosis method of a battery is provided. In the diagnosis method, based on an internal state of the battery at a plurality of mutually different times, a time when the internal state of the battery becomes a predetermined state after the plurality of mutually different times is estimated.

Wireless energy transfer to transport based on route data

An example operation includes one or more of determining, by a transport, an energy transfer condition exists along a route, routing, by the transport, to a location on the route based on the energy transfer condition exceeding an energy transfer value and based on one or more traffic conditions, aligning, by the transport, a position of the transport at the location to wirelessly receive an energy transfer, and receiving, by the transport, the energy transfer while the transport is in motion.

Transmitting Notification Messages for an Electric Vehicle Charging Network

An electric vehicle charging station network server that manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) that indicate one or more events of interest for which the subscriber wishes to receive notification messages. A set of one or more contact points associated with the subscriber is also received. The server receives data associated with the subscriber that indicates that a charging session at one of the charging stations has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.

Aid for inductive battery charging of a motor vehicle

A method for assisting with the positioning of a motor vehicle for inductive charging of a battery of the motor vehicle comprises reading a number plate associated with the motor vehicle using the number plate information to produce a location on the vehicle of a vehicle inductive coupling point (VICP) with reference to at least one reference point on the motor vehicle, comparing a predicted current position of the VICP to a fixed inductive coupling point (ICP) located in or on a road surface upon which the motor vehicle is to be positioned, and providing feedback to one of the driver and the motor vehicle indicative of the required action required to produce alignment of the VICP with the ICP. The method may further comprise energizing the ICP to charge the battery of the motor vehicle when the VICP is predicted to be aligned with the ICP.
