Operation for performing diagnostics, such as vehicle diagnostics including short circuit and low impedance diagnostics during a high-voltage (HV) battery pre-charging a power-net of the vehicle and including insulation resistance monitoring diagnostics for measuring an insulation resistance between the power-net and another power-net, with reduced processing time includes measuring a physical parameter (voltage or current signal) as the parameter is being generated by a device-under-test to which the diagnostic process pertains. The diagnostic process requires a stable value of the parameter. The parameter variates while being generated during a beginning time and is stable while being generated during an ending time. While the parameter is being generated during the beginning time, a stable value of the parameter which the parameter will have during the ending time is predicted. The stable value of the parameter is predicted based on variation of measured values of the parameter during the beginning time.

Provided is a technique for monitoring energy consumption in an electric vehicle (EV) charging network. The technique is based on using messages from one or more EV charging stations, each of which comprises a timestamp, a station ID, a charging session ID, and an energy meter reading. Whenever a new message is received, it is first stored in a database, whereupon it is checked whether the database comprises an older message with the same station ID and charging session ID as the new message. If the older message is present in the database, a time difference and an energy difference between the new and older messages are calculated. Then, a time granularity level is selected based on the time difference. An energy consumption distribution between the timestamps of the new and older messages is obtained based on the time granularity level and the energy difference.

A vehicle includes an accelerator pedal, an electric machine, and a controller. The electric machine is configured to propel and brake the vehicle according to a one-pedal driving operation. The controller is programmed to, in response to depressing the accelerator pedal, command a desired torque to the electric machine. The controller is further programmed to, adjust the desired torque based on a gradient of a road surface that the vehicle is positioned on. The controller is further programmed to, in response to movement of the electric machine in a direction that is opposite to a desired direction while the adjusted desired torque is being applied, increase the adjusted desired torque by a compensation torque such that movement of the electric machine transitions to the desired direction.

A method for charging a traction battery of an electric vehicle includes, in response to a request to charge a traction battery, initially discharging the traction battery, for a first duration of time, according to a discharge stage having a constant power; subsequently charging the traction battery, for a second duration of time, according to a charge stage having a constant current; and repeating the discharge stage and the charge stage in sequence until the battery is charged.

A method and apparatus for parking lot metering. The present invention allows multi-space meters to separately manage and control premium parking spaces, such as those for charging electric vehicles or those which supply electric power for engine block heaters in both pay-by-space and pay-an-display systems. Such premium spaces can be managed together over large areas (e.g., a city or region), or may be managed over smaller areas (e.g., the domain of an individual kiosk), or individually per parking space. Management includes pricing, time limits, hours, seasons of operation, and restrictions by vehicle type, and alternative pricing and restrictions for non-premium hours.

An example operation includes one or more of determining an estimated arrival time of a first transport to a charging station, determining an estimated remaining stored transport energy at the estimated arrival time of the first transport, notifying the first transport to provide a portion of the determined remaining stored transport energy and when a next transport is delayed to the charging station, notifying the first transport to provide an additional portion of the determined remaining stored transport energy based on the delay.

A method for controlling a vehicle brake system of a heavy duty vehicle, the brake system comprising a service brake system and an electrical machine brake system. The method includes determining a total brake torque request for braking a wheel of the vehicle, obtaining a brake torque capability of the electrical machine, determining if the total brake torque request exceeds the brake torque capability of the electrical machine, and if the total brake torque request exceeds the brake torque capability of the electrical machine but is below a threshold level, applying a baseline brake torque by the service brake system, wherein the baseline brake torque is configured to compensate for a difference between total brake torque request and brake torque capability of the electrical machine, and controlling wheel slip by the electrical machine brake system.

A method of calculating an aging degree of a battery, the method including obtaining a duration of the battery in a first state, when a use state of the battery is changed from the first state to a second state, determining whether the obtained duration is greater than or equal to a first reference time, calculating an average temperature of the battery based on a first algorithm when the duration is less than the first reference time, and calculating the average temperature of the battery based on a second algorithm when the duration is greater than or equal to a reference time, and calculating the aging degree of the battery based on the calculated average temperature.
