An electrified tractor includes a vehicle body, a working machine, an electric motor, a battery, an inverter that controls input-output electric power of the battery. The electrified tractor includes a control device that controls the inverter. The control device executes a restriction process, a charging rate calculation process and a relaxation process. In the restriction process, the control device controls the inverter such that the input and output of the battery is restricted within a prescribed electric power range, when a state of the battery satisfies a restriction condition. In the charging rate calculation process, the control device calculates a charging rate of the battery when it is assumed that a work is finished in a farming field, as an estimated charging rate. In the relaxation process, the control device expands the prescribed electric power range, when the estimated charging rate is higher than a first prescribed charging rate.

An in-vehicle system is provided with a front J/B and a first voltage detection unit. The front J/B has a main relay unit, a second voltage detection unit, and a second MCU. Based on detection results detected by the first voltage detection unit and a second voltage detection unit when the main relay unit is subjected to on/off operations, the second MCU monitors whether each of the main relay unit, the first voltage detection unit, and the second voltage detection unit has abnormality or not.

A system and method monitors occupancy and electric vehicle charging activity at parking spaces to optimize charging availability and to electric vehicles and parking/charging control systems using various obtained data, and the use of the data to compute and dynamically adjust parking regulations, charging time and resulting alerts to customers and facility operators, to improve the management of energy consumption and control and manage as well as increase parking/charging station utilization.

Electric vehicle charging management methods and systems are provided. A server performs a charging scheduling operation for each electric vehicle charging station to determine a specific time point for each electric vehicle charging station to perform a charging operation in which the charging operation is to charge an electric vehicle coupled with the electric vehicle charging station. When the charging operation corresponding to each electric vehicle charging station is being performed, each electric vehicle charging station transmits charging information corresponding to the charging operation to the server through a network. The server determines whether the charging operation of specific electric vehicle charging station among the electric vehicle charging stations is abnormal based on the charging information received from each electric vehicle charging station, and generates a warning notification and sends the warning notification through the network when the charging operation of the specific electric vehicle charging station is abnormal.

A marine power pedestal is disclosed. The power pedestal is configured to connect to a mobile device comprising a main body, one or more electrical power units disposed in the main body and configured to conduct power to a marine vessel, one or more display screens, one or more sensors. A controller including a network interface is configured to communicate with a mobile device via a communication network, transmit data to a server via the communication network, and execute commands received, via the communication network, from the server or the mobile device.

A computing system can receive and compile power cell data, and in certain examples, the power cell data can be distributed to a distributed ledger. The computing system can further determine approximate battery end of life (ABEL) for each power cell based on a compiled historical record of power cell data. Based on the determined ABEL, the computing system can generate ABEL reports for users, determine optimal settings for a power cell or battery-powered device, and/or transmit notifications to users, to facilitate power cell usage optimization, and/or optimal repurposing or recycling timing.

A vehicle system of a hybrid vehicle includes: a navigation device that searches a movement path to a destination of a vehicle; and a vehicle control device configured to predict driving energy of a road section included in the movement path according to a vehicle speed of the vehicle when the movement path includes an exhaust gas emission restriction zone, predict first consumption State of charge (SOC) value of the battery consumed within the exhaust gas emission restriction zone based on the driving energy for a case in which the vehicle drives in the exhaust gas emission restriction zone without driving the engine, determine a target SOC value of the battery at a time when the vehicle enters the exhaust gas emission restriction zone based on the predicted first consumption SOC, and control the operation of the vehicle.

When it is determined that a tractor is located in a farm field, a first handling process of performing a first treatment for handling an abnormality when a first condition has been satisfied and a second handling process of performing a second treatment for handling an abnormality when a second condition has been satisfied are performed. The first condition is a condition that is satisfied when the second condition has been satisfied and that is satisfied in some situations in which the second condition has not been satisfied.

A power supply system includes a first power circuit coupled to a capacity-type first battery and a drive motor, a second power circuit coupled to an output-type second battery, a voltage converter that converts a voltage between the first power circuit and the second power circuit, and a converter ECU and a management ECU that operate the voltage converter to control converter passing power in the voltage converter. The management ECU sets, when a first SOC that is a percentage of charge in the first battery is less than a predetermined lamp-on threshold and a first maximum output P1_lim that is a maximum output of the first battery is more them a predetermined output threshold Pe0 maximum converter passing power Pcnv_max corresponding to maximum power with respect to the converter passing power to 0 to prohibit discharging of the second battery.

Aspects of the invention are directed towards a system and method for safe decoupling of the external power supply from a vehicle. The technology described herein provides an indication or an alert to the user at an appropriate time and avoids the possible damage to the system. The system comprises an electrical port by which the refrigerator can be connected to an external AC mains supply via an electrical cable when the vehicle is in stationary state. The system further comprises a refrigerator main controller unit (RMU) for controlling the power delivered to the refrigerator in both stationary and driving states of the vehicle. There is a safety system installed for restricting the vehicle from being driven when the electrical port of the system is connected to the AC mains supply via the electrical cable and the refrigerator is powered by the AC mains supply.
