A battery system includes a rechargeable energy storage system and a battery controller. The rechargeable energy storage system has a rapid charging mode and a discharging mode. The battery controller is electrically coupled to the rechargeable energy storage system and is configured to store multiple charging tables that contain multiple charge current limit entries, where each charging table corresponds to a unique one of multiple initial state-of-charge values, determine a starting state-of-charge value of the rechargeable energy storage system in response to entering the rapid charging mode, select up to two charging tables in response to the starting state-of-charge value of the rechargeable energy storage system being adjacent to up to two of the initial state-of-charge values, and control a charging current provided to the rechargeable energy storage system based on the charge current limit entries in the up to two charging tables as selected.

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.

A refuse vehicle includes a vehicle chassis and an all-electric vehicle body on the chassis. The body includes a hopper, a refuse storage container, and a plurality of electrically powered body systems. The body systems include an electrically actuated tailgate, an electrically actuated refuse loading assembly, and an electrically actuated refuse packing assembly configured to remove refuse from the hopper and to pack said refuse in the storage container. The vehicle (e.g., vehicle body) further includes a power management module configured to regulate energy usage of the body systems and/or to record and track electrical energy usage in the body systems.

An ECU switches a control mode to an HV mode when an SOC decreases to a lower limit during an EV mode. The ECU calculates an evaluation value ΣD of high-rate deterioration indicating a deterioration component of a secondary battery due to non-uniformity in salt concentration in a battery. The ECU executes high-rate deterioration inhibiting control when the HV mode is currently selected and when the battery is evaluated as deteriorating based on the evaluation value ΣD, the high-rate deterioration inhibiting control being control for increasing the SOC by making a control target of the SOC higher than the lower limit of the SOC. On the other hand, the ECU does not execute the high-rate deterioration inhibiting control when the EV mode is currently selected.

A vehicle control device mounted on a vehicle includes a power storage device, a drive device configured to be driven by electric power from the power storage device, a system main relay attached to a power line between the power storage device and the drive device, and a charge circuit connected to a side of the drive device through the system main relay of the power line, in which the vehicle control device is configured to turn off the system main relay and prohibit reactivation of the system in a power shortage of the power storage device. The vehicle control device is configured to permit the system main relay to be turned on in a case where charging of the power storage device using the charge circuit is requested.
