Systems, methods, devices, and models for range estimation and analysis in battery powered vehicles are described. Energy consumption over vehicle trips is collected, to evaluate weighting factors for a weighted sum. The weighted sum is evaluated based on determined weighting factors and expected trip data, to determine an energy consumption of a trip or trips of a vehicle. Determined energy consumption for trips is used for evaluating suitability of the vehicle for performing the trips.

A shifting device for an electric vehicle having a virtual manual transmission system, that is configured to realize a variety of shift patterns and torque characteristics. The shifting device comprises: an indicator that indicates a shift pattern; and an indication switcher that switches the shift pattern indicated in the indicator to another pattern. At least any one of the number of the shift positions and a virtual gear stage assigned to the shift position in the shift pattern switched by the indication switcher is different from that in the previous shift pattern indicated in the indicator before switched by the indication switcher.

A method for balancing an electric vehicle is provided, in which a controller of an electric vehicle variably adjusts the disposition of a bracket with battery modules of a traction battery of the electric vehicle situated in the bracket relative to a chassis of the electric vehicle. An electric vehicle is also provided.

A method of generating a virtual internal combustion engine vibration in an electric vehicle includes collecting driving variable information, determining a virtual internal combustion engine vibration characteristic on the basis of the collected driving variable information, determining a vibration torque command having the determined virtual engine vibration characteristic, determining a final motor torque command using a basic motor torque command determined from the collected driving variable information and the determined vibration torque command, and controlling the operation of a vehicle driving motor according to the determined final motor torque command.

An electric vehicle charging control method and apparatus related to the technical field of electric vehicle charging. The method includes: periodically obtaining a working temperature; maintaining a charging power output to an electric vehicle at a first charging power and triggering a first prompt signal, when the working temperature is greater than or equal to a first temperature threshold and less than a second temperature threshold; reducing the charging power output to the electric vehicle from the first charging power to a second charging power when the working temperature is greater than or equal to the second temperature threshold and less than a third temperature threshold; and stopping charging the electric vehicle when the working temperature is greater than or equal to the third temperature threshold. Therefore, the charging efficiency can be improved and the charging time can be shortened on the premise of ensuring the charging safety of the electric vehicle.

A system or method for vehicle-side control of a multi-pile charging session, the system comprising: (a) a plurality of charging piles (10A), each charging pile (10A) including a supply equipment communication controller (10B); and (b) a vehicle electrical system for an electric vehicle with a master battery control unit (18) in data communication with a plurality of battery control units (BCU.sub.0, BCU.sub.1, BCU.sub.2). The master battery control unit (18) is configured to coordinate two or more independent charging sessions through the battery control units (BCU.sub.0, BCU.sub.1, BCU.sub.2) during each multi-pile charging session. Each independent charging session is managed with an independent protocol message exchange through a BCU-to-SECC communication pathway (22) established by power line communication.

A method to control a road vehicle during a slip of the drive wheels and having the steps of: detecting a slip of at least one drive wheel; and controlling, only during a slip of at least one drive wheel, a driving unit of the road vehicle with a signalling law so as to obtain a cyclic operating irregularity, which generates an abnormal vibration and/or an abnormal noise.

A power transfer managing apparatus includes: a demand information acquiring unit that acquires information indicating power demand in a power network; a selecting unit that selects, as a vehicle to be caused to perform power transfer with the power network according to the power demand, a vehicle provided with a driving power source having an accumulated energy amount larger than a predetermined accumulation amount, and having an accumulatable energy amount larger than a predetermined accumulatable amount; and a notification control unit that makes a user of the vehicle that is selected by the selecting unit notified.

A vehicle control apparatus mounted on a vehicle including a DC-DC converter that supplies electric power from a first battery to a second battery and an auxiliary load includes an electronic control unit configured to control an operation of the converter, determine a state of a starter switch of the vehicle, detect a user operation to the vehicle, and acquire charging status information of the second battery. The electronic control unit is configured to, when the electronic control unit detects a first operation by the user and determines that the starter switch is off, drive the converter such that the converter charges the second battery, and, when an electric power amount charged in the second battery reaches a target amount of charge set based on an amount of electric power to be consumed by the auxiliary load while the starter switch is off, stop the converter.

The invention relates to a method for operating an electric energy store (1), to an electric energy store (1), and to a device, having an electric energy storage module (18), a switch unit (4), and a first and second connection (5, 7).
