A method for detecting a bad contact of a charging cable comprises: measuring a cooling fluid temperature of a cooling fluid flowing through the charging cable; measuring a connector base temperature of a connector base of the charging cable, which connector base carries an electrical contact element of the charging cable; estimating a contact temperature of the electrical contact element by determining the contact temperature from a difference of the connector base temperature and the cooling fluid temperature; and deciding presence of a bad contact, when the estimated contact temperature is higher than a threshold temperature.

A heat exchanger includes: a baseplate having a first side and a second side opposite the first side, the first side being coupled to a thermosiphon, one or more electronic components being mounted on the second side. The baseplate has a two-phase heat spreading structure. In an embodiment, the heat exchanger includes a thermosiphon.

The invention relates to a method which is suited for manufacturing a 3D-vapor chamber in a defined and efficient manner. Especially, the present method provides a solution for providing a vapor chamber having an evaporator and a condenser made from a first part and a second part, wherein continuity of internal structures is given which in turn provides an efficient working behaviour of the vapor chamber.
