Abstract:
A battery charger (B1) for electric vehicles, composed of at least three identical current controlled AC-DC converter modules (M1, M2, M3) having reverse current protected outputs connected in parallel to a charge terminal of the battery (44).
Abstract:
The present invention relates to a charger for charging the battery of an electric vehicle, comprising at least one port for exchanging electric power and/or data with a vehicle during a charge session, first data communication means, for saving information regarding the charge session to a data storage location, second data communication means, for communicating a reference for obtaining access to the data storage location comprising the information regarding said charge session to an external device.
Abstract:
The present invention relates to a method for determining the charging behaviour, comprising obtaining the parameters from an electric vehicle, estimating the charging characteristics based on at least the parameters, measuring the actual charging characteristics of the electric vehicle and using the actual charging characteristics to improve the estimation of the charging characteristics.
Abstract:
System for charging a battery of at least one electric vehicle, comprising at least one sensor, arranged for measuring at least one parameter representing a power supplied by the phase output of the power supply or an asymmetry between the phase outputs of the power supply, and providing at least one sensor signal representing the value of the at least one parameter, a controller coupled to the at least one sensor at the power output ofthe power supply for receiving all sensor output signals, and coupled to the charging configuration for controlling the power of the power converter thereof, wherein the controller is configured for controlling the power exchanged for at least one phase of the power supply and the charging configuration according to a control model.
