Abstract:
A method of operating a RESS thermal system in a vehicle having a coolant loop for directing a coolant through a RESS and a refrigerant loop configured to selectively cool the coolant flowing through a chiller in the coolant loop, including: determining a current target temperature range for the RESS based on a current vehicle operating mode and ambient temperature; determining a temperature of the RESS; determining if the temperature of the RESS needs to increase or decrease to be within the current target temperature range; if the determination is made that the temperature of the RESS needs to increase, determining if an active heating or a passive heating of the coolant will be employed, the active heating using a greater amount of energy over a shorter time period than the passive heating; and activating the determined active heating or passive heating of the coolant.
Abstract:
A power supply system comprises a chargeable power storage device; a charging device configured to perform external charging for charging the power storage device using alternating-current power supplied from an external power supply; an air conditioner receiving electric power from the charging device and the power storage device and air-conditioning a compartment in a vehicle; an auxiliary machinery load; and an ECU. The ECU controls at least one of the charging device and the auxiliary machinery load so as to increase the electric power output from the power storage device in a case where overcharging of the power storage device is expected when the air conditioner is intermittently operated during external charging.
Abstract:
A method is disclosed that defines a protocol for distributing power to high voltage components when two conditions exist: they being when the vehicle is being propelled or operated and when the power requested of the power supply is less than what the power supply can provide. The method determines which high voltage components can receive reduced or intermittent voltage and still allow the vehicle to operate in a proper manner. Calibrations of the usage and energy loss are based on parameters that dictate how important it is that a particular high voltage component receives as much of its requested power as possible. The critical function components will be weighted differently than those less critical components.
Abstract:
A charge port receives power supplied from a power supply on the outside of a vehicle. A charger is constituted to charge a power storage device by performing voltage conversion of power inputted from the charge port. A block heater warms up an engine by receiving an operating power from the charger. When the block heater is connected with a power supply port which is connected electrically with the charger, an ECU controls the charger to give priority to power supply to the block heater over charging of the power storage device.
Abstract:
An air conditioning system that can operate an air conditioner of an electric vehicle without interfering with the charging process, which utilizes a secondary battery. When operation of the vehicle is terminated and the control system determines that a frosting judgment decision is positive, the control system judges whether the charging current has dropped to a specified level or less. As soon as the charging current has dropped to or below the specified level, the excess charging current may be used for a defrosting operation. When the operation of the vehicle is stopped and the control system determines that a frosting judgment decision is negative, the control system judges whether a preliminary air conditioning switch is on. If the preliminary air conditioning switch is on, it is judged whether charging of the secondary battery is in progress. If charging is progressing, the control system determines whether the charging current has dropped to or below a specified level. As soon as the charging current has dropped to or below this specified level, preliminary air conditioning is performed to cool or warm the cabin of the vehicle during charging of the secondary battery.
Abstract:
A mining vehicle has a body with a center boom extending forwardly from the body. A temporary roof support is mounted on the outer end of the center boom. The roof support has a base, a telescopic column, and a cross beam on top of the column with auxiliary beams pivotally connected to the cross beam to engage the roof. Hydraulic jacks are connected between the base and the outer ends of the beams, respectively. A pedestal is pivotally mounted on the front end of the body, on each side of the center boom, to support a drill boom. A drill head is pivotally mounted at the outer end of the drill boom and is vertically movable by the drill boom for roof drilling. Each drill boom has the end opposite the drill head received in a track on the pedestal which serves to maintain the drill head on a vertical axis in any position of the drill boom. Each pedestal, at its inner end, has a laterally extending arm, the outer end of which is pivotally connected to the body at a pivot joint. A swing jack is connected between the body and the arm to swing the pedestal and drill boom about the pivot joint.
Abstract:
A vehicle includes a temperature control system, a battery configured to power the temperature control system, and a controller. The controller is programmed to, in response to a request to precondition the battery or the cabin air, an absence of receiving a signal indicative of a desired initial battery state of charge, and an actual battery state of charge being greater than a default threshold, deliver electrical power from the battery to the temperature control system at a desired value. The controller is further programmed to, in response to the request to precondition the battery or the cabin air, receiving the signal indicative of the desired initial battery state of charge, and the actual battery state of charge being greater than the desired initial battery state of charge but less than the default threshold, deliver electrical power from the battery to the temperature control system at the desired value.
Abstract:
The invention relates to an electrical device for melting snow and ice that has accumulated on the surface of a. vehicle. During inclement weather, snow, sleet, rain or hail accumulate on all exposed surfaces of the automobile, in particular on the flat surfaces, such as on the roof the hood, the trunk, or a truck bed of a vehicle. These areas of snow coverage are relatively large and significantly high off the ground, presenting a challenge to clean in terms of time and effort. Frequently, the owners of the vehicles need to use their automobiles early in the morning, when snow or ice that has accumulated over night is at its hardest. Since it is unsafe, and sometimes unlawful, to operate a vehicle that has not been properly snow dusted and deiced, cleaning must be effectuated before a vehicle can be driven on the roads.
Abstract:
A vehicle includes a traction battery configured to be coupled to a power network that is controlled by a grid management system. The vehicle further includes a controller. The controller charges the traction battery and activates vehicle loads based on a request from the grid management system to consume an amount of power from the power network. When the traction battery is fully charged, one or more vehicle loads are activated to consume the amount of power. When a charge power limit of the traction battery is greater than or equal to the amount of power requested, the traction battery is charged to consume the amount of power requested.
