Storage battery charging station

Abstract

A charging station ( 1 ) for a rechargeable battery ( 5 ) that can be electrically and physically connected to the rechargeable battery ( 5 ). The charging station ( 1 ) has charger electronics ( 2 ) in a charger housing ( 3 ) and an electrical and physical contact interface ( 4 ) for the battery ( 5 ). An air blower ( 6 ) producing an air current (L) through two air vents ( 7 a, 7 b) is arranged in the charger housing ( 3 ). The air vent ( 7 a) of the physical contact interface ( 4 ) is spatially associated with the battery ( 5 ) and the charger electronics ( 2 ) is arranged in the air current (L) to transfer heat. In the cooling process, in a first stage, an air volume (V) at cooling temperature CT is moved past the battery to transfer heat into and onto the battery and, in a second stage, the air volume (V) at an intermediate temperature IT>CT permeates the charger housing ( 2 ) containing the charging electronics ( 2. ).

1. A charging station for a rechargeable battery ( 5 ) that can be physically and electrically connected to the battery ( 5 ) having charger electronics ( 2 ) in a charger housing ( 3 ) and an electrical contact interface ( 4 ) for the battery ( 5 ) that interfaces a vent ( 7 a), wherein an air blower ( 6 ) is arranged in the charger housing ( 3 ) for producing an air current (L) through two air vents ( 7 a,  7 b), wherein one of the two air vents ( 7 a) faces the battery ( 5 ), and wherein the charger electronics ( 2 ) is arranged to transfer heat in the air current (L) and wherein the air blower ( 6 ) is arranged between the air vent ( 7 a) on a flow inlet side and the charger electronics ( 2 ). 
     
     
       2. The charging station of  claim 1 , wherein the air vent ( 7 a) on a flow inlet side faces the battery ( 5 ). 
     
     
       3. The charging station of  claim 1 , wherein the air vent ( 7 a) on the flow inlet side forms a plurality of surface-distributed air inlet points ( 8 ) each associated with cooling vents ( 9 ) of the battery ( 5 ). 
     
     
       4. The charging station of  claim 3 , wherein a pressure chamber ( 10 ) causing air to be distributed is arranged between the air blower ( 6 ) and the air inlet points ( 8 ). 
     
     
       5. The charging station of  claim 1 , wherein the air vent ( 7 a) on the flow inlet side is arranged in an upper section ( 13 ) of the charging station ( 1 ). 
     
     
       6. A cooling process for a charging station ( 1 ) for a rechargeable battery ( 5 ) that is electrically and physically connected to the battery ( 5 ), wherein an air volume (V) of an air current (L) is moved by an air blower ( 6 ) arranged in the charger housing ( 3 ) of the charging station ( 1 ), comprising, a first step, wherein the air volume (V) at a cooling temperature CT is moved into the battery ( 5 ) to transfer heat, and, in a second step, the air volume (V) at an intermediate temperature IT>CT permeates the charger housing ( 3 ) containing the charger electronics ( 2 ). 
     
     
       7. A charging station for a rechargeable battery (5) that can be physically and electrically connected to the battery (5), comprising a charger housing (3) having an electrical contact interface (4) for physically and electrically connecting the charger housing (3) with the rechargeable battery (5); charger electronics (2) located in the charger housing (3); and an air blower (6) for producing air flow through two air vents (7a, 7b) and located in the charger housing (3), wherein one of the two air vents (7a) faces the battery (5), and the charger electronics (2) is located, in the direction of the air flow, downstream of the battery (5) and upstream of another of the two air vents (7b), whereby an environmental air volume having a cooling temperature flows through the battery for cooling the same and then at an intermediate temperature, permeates the charger housing (3), cooling the charger electronics (2).
