In hybrid electric vehicles having increased battery storage capacity and plug-in capability, electric-only operation of significant duration is available. To supplement lubrication for the electric and mechanical components provided in a fluid circuit by an engine-driven mechanical pump, an electric pump is provided in parallel to the mechanical pump. When the electric pump is operating, a diagnostic can be performed to determine system integrity. According to one embodiment, an actual quantity provide to the circuit is determined; an expected quantity is estimated; and a fault is determined when the actual and expected quantities differ by more than a predetermined amount. The fault may indicate a leak or plug in the fluid circuit or a failure of a component in the fluid circuit.

System and method to provide lubrication for a plug-in hybrid

A vehicle wireless information system includes a vehicle, an onboard vehicle computer provided in the vehicle and at least one external access point adapted to wirelessly access the onboard vehicle computer.

Vehicle wireless information system

A battery electrical vehicle or plug-in hybrid electric vehicle includes a battery which may be charged by an electrical charging station coupled to the electric power grid. To maximize the charging efficiency thus decreasing charge time, the voltage and current drawn from the power grid may be closely monitored. Based on the monitoring of the voltage and current of an electrical circuit powering a battery charger, a notification of changing conditions to charging characteristics including electric circuit wiring resistance, power loss or wiring efficiency may be generated.

Vehicle battery charging system notification

A charge station includes a controller that initiates charging of a battery of a vehicle and notifies the vehicle in response to an electrical parameter measured and reported by the vehicle not being approximately equal to a same electrical parameter measured at the charge station. The electrical parameter may be power, voltage or current.

In hybrid electric vehicles having increased battery storage capacity and plug-in capability, electric-only operation of significant duration is available. To supplement lubrication for the electric and mechanical component provided by an engine-driven mechanical pump, an electric pump is provided in parallel to the mechanical pump. A method to control the electric pump is also disclosed in which a first desired quantity of a first component and a second desired quantity of a second component are determined. The electric pump is commanded to provide the greater of the first and second quantities. The desired quantity can be based on preventing temperature in the component from exceeding a maximum design temperature and/or providing sufficient lubrication to rotating parts of the component.

A vehicle power system includes a traction battery and a battery charger. The battery charger has an electrical output and a capacitor electrically connected with the electrical output. No more than two electrical contactors are electrically connected with the traction battery, capacitor and battery charger.

System and method for vehicle battery charging

A vehicle includes an auxiliary battery and one or more accessory loads. An accessory load command is modulated such that the auxiliary battery outputs a discharge current to an accessory load. The discharge current has, in addition to a current component for driving the accessory load, an alternating current (AC) component to cause a temperature of the auxiliary battery to increase.

Method and system for heating auxiliary battery of vehicle

A method for diagnosing a battery may include applying a generally constant current to the battery for a period of time, measuring a response voltage of the battery to the applied current, determining battery impedance parameters based on at least one of the applied current, period of time, and response voltage, and determining a degradation condition of the battery based on the battery impedance parameters.

Vehicle and method of diagnosing battery condition of same

A system includes an isolation detection unit (IDU) having a first leakage detection circuit and being configured to determine an isolation characteristic for a voltage bus; and a circuit detection and response unit (CDRU) configured to determine whether the first leakage detection circuit is coupled to a second leakage detection circuit by a common ground. The CDRU can use a change in isolation characteristic of the voltage bus to determine whether a second detection circuit is coupled, and can characterize a coupled circuit. IDU operation and fault detection thresholds can be altered to mitigate confounding effects caused by simultaneous operation of both circuits. A system can be disposed at an electric vehicle to detect coupling of a detection circuit at a charging apparatus, or disposed at a charging apparatus to detect coupling of a leakage detection circuit at an electric vehicle.

Detection of and response to second leakage detection circuit

An electric vehicle such as a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), and a battery-only electric vehicle (BEV) includes a traction battery. A torque command is generated for a motor such that a traction battery electrically connected therewith outputs a discharge current having an alternating current (AC) component to cause a temperature of the traction battery to increase.

Method and system for heating traction battery of electric vehicle

A vehicle computer is programmed to receive weather data from a remote server, to determine a frequency, based on the weather data, to obtain precipitation data from one or more vehicle sensors. The computer is further programmed to obtain the precipitation data, and to close one or more vehicle windows based at least in part on the precipitation data.

Vehicle window management

An automotive vehicle may include a battery charger that receives electrical energy, via an electrical connection including a ground wire, from an electrical source remote from the vehicle, and outputs the electrical energy to at least one electrical load. The vehicle may also include at least one controller that commands a change in the electrical energy output by the battery charger. The battery charger, in response to the command, may control a rate of change in the electrical energy output such that a coupling current to the ground wire resulting from the change in the electrical energy output by the battery charger has a magnitude less than a predetermined threshold.

System and method for controlling chassis coupling current

A vehicle may include a battery that receives energy from a charge station remote from the vehicle, and a controller. The controller may request that the station provide information about an electrical parameter associated with energy being supplied by the station, may determine information about an electrical parameter associated with energy received by the battery, and may prevent the battery from further receiving energy if the provided information is different than the determined information.

An exemplary battery charge monitoring method includes, among other things, calculating expected charge data for a battery using at least a capacity of the battery and a charge rate, and comparing actual charge data to the expected charge data to identify differences between the actual charge data and the expected charge data.
