摘要： A portable high voltage charging apparatus (HVCA) can be configured to controllably charge a hybrid electric vehicle (HEV) traction battery using energy provided by a low voltage (LV) lead acid vehicle battery. An HVCA can include a DCDC converter configured to boost a lower input voltage from the LV battery to a higher output voltage provided to the HV battery. The HVCA can be configured with a traction battery interlock, allowing offline charging of the traction battery. In an example embodiment, an HVCA can be configured to communicate with an HV battery control module via a CAN bus. An HVCA can be configured to transfer energy to the HV battery for a predetermined time period, then automatically stop the transfer process. An HVCA can be configured to receive user input to start and/or stop a charging process. An example embodiment can include a supplemental charger to boost LV battery voltage.

摘要： A first fuel consumption value is determined for operating a host vehicle in a first lane on a road surface. A second fuel consumption value is predicted for operating the host vehicle in a second lane on the road surface based on acceleration data for a target vehicle operating in the second lane. A request to move the host vehicle from the first lane to the second lane is transmitted to the target vehicle based on the predicted second fuel consumption value being greater than the first fuel consumption value. After receiving an acknowledgement from the target vehicle, the host vehicle is operated from the first lane to the second lane.

摘要： An electrical leakage detection circuit detects electrical leakage of a battery in an electric vehicle. A first transistor switch coupled between a first and second resistor is actuated for coupling the first resistor and the second resistor. A second transistor switch coupled between a third and fourth resistor is actuated for electrically coupling the third and fourth resistor. A controller generates control signals for actuation of the first transistor switch and the second transistor switch. A first voltage is measured across the traction battery cell string. A second voltage is measured across the second resistor. A third voltage is measured across the third resistor. The controller detects electrical leakage by measuring the first, second, and third voltages and applying them in equations utilizing these voltages with constants of the first, second, third, and fourth resistances.

摘要： Systems, apparatus, and methods are presented to transfer energy between an energy storage device (ESD) at an electrified vehicle (EV) and an AC or DC external load such as an electric grid, appliance or power tool. A portable EVETA can engage an EV charge inlet couple an EV, and can provide an AC outlet, a grid interface and a DC connector for coupling external loads. An EVETA can be used at a remote construction site or campsite to power high current equipment, obviating the need to transport an electric generator. An EVETA can be configured for data and control communication with the EV to coordinate energy transfer. An EVETA can receive a predetermined ESD state of charge limit so that the transfer process can be terminated to preserve sufficient charge for EV return to a desired destination. A human machine interface enables user input reception and information display.

摘要： A multi-cell battery pack in an electric vehicle is monitored by multiple sensing modules. A primary controller is coupled to a first plurality of cells to measure a predetermined parameter of each cell. The primary controller determines a sampling moment recurring at a fixed frequency for sampling the predetermined parameter of each of the first plurality of cells. The primary controller generates a sync pulse at each sample moment. A secondary controller is coupled to a second plurality of cells to measure the predetermined parameter of each cell. The secondary controller receives the sync pulse to start a pulse generator operating at a frequency which is a predetermined multiple of the primary controller fixed frequency. The secondary controller counts pulses generated by the pulse generator and schedules a synchronized secondary sampling moment according to a predetermined pulse count.
