Based on the user's travel information the process determines (i) an optimal charge level that maximizes the battery pack's lifetime while assuring that there is sufficient energy for the vehicle to travel the intended distance and (ii) an optimal charging rate that maximizes the battery pack's lifetime while assuring that the battery pack is charged to the optimal charge level prior to the intended time of departure. Safety margins may be added to the user's travel information, thus insuring that the car is charged and ready for use if the user decides to leave earlier than expected, or if the travel takes a larger charge than expected. | 05-26-2016 |

20160164322 | WEAK COMPONENT DETECTION FOR CHARGING CAPACITY CONTROL - A charger and a mobile device exchange messages indicating that high wattage charging is supported over a bidirectional communication channel. After the message exchange, the charger sends a controlled output voltage and current to the mobile device over a cable connected between the charger and the mobile device. The mobile device takes an input voltage measurement that corresponds to the controlled output voltage after being passed through the cable. The charger or mobile device may then calculate a resistance of the cable based on a difference between the controlled output voltage and the input voltage measurement. Based on the resistance of the cable, the controlled voltage and current used to charge a battery of the mobile device is adjusted in order to avoid exceeding capacity of the cable. | 06-09-2016 |
20160164337 | FAR FIELD TELEMETRY OPERATIONS BETWEEN AN EXTERNAL DEVICE AND AN IMPLANTABLE MEDICAL DEVICE DURING RECHARGE OF THE IMPLANTABLE MEDICAL DEVICE VIA A PROXIMITY COUPLING - Far field telemetry operations are conducted between an external device and an implantable medical device while power is being transferred to the implantable medical device for purposes of recharging a battery of the implantable medical device. The far field operations may include exchanging recharge information that has been collected by the implantable medical device which allows the external device to exercise control over the recharge process. The far field operations may include suspending far field telemetry communications for periods of time while power continues to be transferred where suspending far field telemetry communications may include powering down far field telemetry communication circuits of the implantable medical device for periods of time which may conserve energy. The far field operations may further include transferring programming instructions to the implantable medical device. | 06-09-2016 |

20160375783 | Identifying a User of a Charging Station - Systems, methods, and other embodiments associated with identifying a user of a charging station. According to one embodiment, a system includes a communication logic and an authorization logic. The communication logic aggregates transaction data to an authorizing entity. The transaction data is associated with a user and a chargeable vehicle. The authorization logic receives an authorization request to authorize a transaction between the chargeable vehicle and the charging station. The authorization logic sends a response to the authorization request. The communication also enables the chargeable vehicle to receive a charge from the charging station based on the response to the authorization request. | 12-29-2016 |

20220135385 | LIFT DEVICE WITH SPLIT BATTERY PACK - A lift device includes a base assembly, a turntable assembly, and a controller. The base assembly includes multiple base assembly batteries. The turntable assembly is rotatably coupled with the base assembly through a slip ring transmission. The turntable assembly includes multiple turntable assembly batteries. The controller is configured to operate the base assembly batteries to discharge electrical energy to the turntable batteries through the slip ring transmission. The slip ring transmission is configured to both (1) drive the turntable assembly to rotate relative to the base assembly and (2) to electrically and communicably couple electrical components of the base assembly with electrical components of the turntable assembly. | 05-05-2022 |
20220140619 | POWER USAGE PATTERN COLLECTOR AND CHARGING CONTROLLER - 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. | 05-05-2022 |
