Embodiment Construction
[0048] figure 1 and figure 2 A high-current charging cable 1 for charging an electric vehicle according to a preferred embodiment is shown in each case in a cross-sectional view. The cable 1 comprises one non-insulated high current ground wire 2 serving as ground, the high current ground wire comprising a ground conductor 3 extending in a longitudinal direction orthogonal to the layer, and a ground wire insulation 4 surrounding the ground conductor 3 . Ground conductor 2 includes 25mm 2 Cross-section.
[0049] The high-current charging cable 1 further includes two high-current power lines 5, each of which is configured to conduct positive and negative direct current DC respectively. The two high-current power supply lines 5 each extend parallel to the ground line 2 and are arranged away from each other and away from the ground line 2 . Each high current supply line 5 comprises a supply conductor 6 and a supply line insulation 7 surrounding said supply conductor 6 . Each ...

Abstract
The invention relates to a heavy-current charging cable (1) for charging an electric vehicle, comprising a ground heavy-current wire (2) configured for serving as ground, the ground heavy-current wire (2) comprising a ground conductor (3) and extending in a longitudinal direction, at least two heavy-current power wires (5) configured for conducting positive and negative direct current, DC, each of said heavy- current power wires (5) comprising a power conductor (6) and a power wire insulation (7) surrounding said power conductor (6), the heavy-current power wires (5) extending parallel to the ground wire, a liquid tight inner sheath (8) extending in the longitudinal direction and surrounding the heavy-current power wires (5), thereby defining a first hollow area (10) between and around the heavy-current power wires (5) comprising liquid coolant to flow between the heavy-current power wires (5) along the longitudinal direction, whereby the liquid tight inner sheath (8) comprises a second hollow area (12) extending in the longitudinal direction, arranged adjacent to at least one of the heavy-current power wires (5) and comprising liquid coolant to flow within the second hollow area (12) along the longitudinal direction, and a liquid tight outer sheath (9) extending in the longitudinal direction and surrounding the inner sheath (8) and the ground heavy-current wire (2).
Description
technical field [0001] The present invention relates to a high current charging cable for charging an electric vehicle, comprising: a high current ground line configured to serve as a ground, the high current ground line including a ground conductor and extending in a longitudinal direction; and configured being at least two high current power lines for conducting positive and negative direct current DC, each of said high current power lines comprising a power conductor and power line insulation surrounding said power conductors, these high current power lines being parallel to Ground wire extension. The invention further relates to an electric vehicle supply apparatus comprising a high-current charging cable and a cooling unit, and a corresponding method for cooling the high-current charging cable. Background technique [0002] Conventional charging cables (especially uncooled or air-cooled charging cables) for charging electric vehicles are used in applications where the ...
