Description

charging device

[0001] The present invention relates to a charging device that can increase the efficiency of charging by distributing power supplied from a power bank to a plurality of dispensers that charge an electric vehicle.

[0002] Typically, electric vehicles (EVs) have been slow to become practical for a long time due to issues such as the heavier weight of the batteries installed in the vehicle compared to gasoline or diesel-powered vehicles and the time required to charge them. However, with the recent depletion of fossil fuels and environmental pollution, interest in EVs, which run on electric energy rather than fossil fuels, has grown, leading to active research and development in this area.

[0003] As a result, the widespread adoption of electric vehicles has increased in recent years. Electric vehicles are equipped with batteries that supply power for propulsion and store energy. Therefore, to keep an electric vehicle running, the batteries must be charged. Consequently, infrastructure for charging electric vehicles is essential, and to meet the growing demand for electric vehicles, fixed-mounted charging stations are being installed in various locations.

[0004] Here, electric vehicle charging facilities are essential for building a stable charging infrastructure that ensures electrical stability and long-term service life. This is because electric vehicle charging facilities are primarily installed outdoors, such as in public buildings, parking lots in parks, highway rest areas, and apartment complexes.

[0005] Electric vehicle charging facilities include power banks with multiple power modules built into them, and multiple dispensers that draw power from the power banks and charge the electric vehicle. To improve electric vehicle charging efficiency, power must be smoothly concentrated or distributed across multiple dispensers.

[0006] In addition, charging facilities for electric vehicles require cooling devices to ensure the stability of the charger connected to the power cable even when power is supplied.

[0007] However, in the past, each dispenser was equipped with a separate cooling device, or the dispenser and cooling device were connected one-to-one to perform cooling individually.

[0008] In this case, the cost of building infrastructure for electric vehicle charging increased because cooling devices were required for the number of dispensers in operation. Furthermore, securing installation space was problematic due to the increased size of the dispensers required to accommodate cooling devices.

[0009] Therefore, a means is required to solve the above-described problem by increasing the efficiency of electric vehicle charging and increasing the cooling efficiency of the dispensers while operating multiple dispensers.

[0010] The present invention relates to a charging device, and more specifically, to a charging device capable of increasing charging efficiency by distributing power supplied from a power bank to a plurality of dispensers that charge an electric vehicle.

[0011] In addition, it is an object of the present invention to provide a charging device capable of distributing power to at least one of a plurality of dispensers by controlling a plurality of switches arranged on a power distribution line connecting a plurality of power modules and a plurality of dispensers.

[0012] In addition, the present invention aims to provide a charging device that can efficiently cool a power cable while miniaturizing the dispenser by having a separate cooling module that is connected to multiple dispensers and supplies coolant.

[0013] In addition, the purpose is to provide a charging device that can secure efficiency in installation space by accommodating a power module and a cooling module through a single housing.

And the 2-4 cable line (1600d) connected to dispenser 4 (1200d) can be connected to the 1-4 power distribution line (1411d).

[0078] The 2-1 power distribution line (1412a) may serve to connect the 1-1 power distribution line (1411a) and the 1-2 power distribution line (1411b). In addition, a first switch (1420a) may be placed on the 2-1 power distribution line (1412a).

[0079] The 2-2 power distribution line (1412b) may serve to connect the 1-2 power distribution line (1411b) and the 1-3 power distribution line (1411c). In addition, a second switch (1420b) may be placed on the 2-2 power distribution line (1412b).

[0106] And the cooling water line (1720) may include a plurality of supply lines (1721) that supply cooling water from the chiller (1710) to a plurality of dispensers (1200). In addition, the cooling water line (1720) may include a plurality of inlet lines (1722) that introduce cooling water that has passed through the plurality of dispensers (1200) into the chiller (1710).

[0108] Furthermore, each of the plurality of dispensers (1200) may include a heat exchanger (1240) connected to a supply line (1721) and an inlet line (1722).

[0109] That is, the charging device (1000) according to one embodiment of the present invention has a separate cooling module (1700) to supply cooling water to a plurality of dispensers (1200), thereby solving the conventional problem of having to provide a cooling device for each dispenser (1200).

[0110] Referring to FIG. 8 together, a plurality of supply lines (1721) supplying cooling water from a chiller (1710) to a plurality of dispensers (1200) may include a first supply line (1721a), a second supply line (1721b), a third supply line (1721c), and a fourth supply line (1721d).

[0111] A first supply line (1721a) may be connected to a first heat exchanger (1240a) of dispenser 1 (1200a). A second supply line (1721b) may be connected to a second heat exchanger (1240b) of dispenser 2 (1200b).

[0112] Additionally, the plurality of inlet lines (1722) that introduce cooling water that has passed through the plurality of dispensers (1200) into the chiller (1710) may include a first inlet line (1722a), a second inlet line (1722b), a third inlet line (1722c), and a fourth inlet line (1722d).

[0113] The first inlet line (1722a) may be connected to the first heat exchanger (1240a) of dispenser 1 (1200a). The second inlet line (1722b) may be connected to the second heat exchanger (1240b) of dispenser 2 (1200b). The third inlet line (1722c) may be connected to the third heat exchanger (1240c) of dispenser 3 (1200c). And the fourth inlet line (1722d) may be connected to the fourth heat exchanger (1240d) of dispenser 4 (1200d).

[0114] In addition, in a charging device (1000) according to one embodiment of the present invention, a plurality of valves (1730) may be arranged on a plurality of supply lines (1721). More specifically, a first valve (1730a) may be arranged on the connection side of the supply line (1721) and the chiller (1710) to serve to supply cooling water to a plurality of dispensers (1200) through opening and closing.

[0115] And the second valve (1730b) may be placed on the first supply line (1721a). The third valve (1730c) may be placed on the second supply line (1721b). The fourth valve (1730d) may be placed on the third supply line (1721c), and the fifth valve (1730e) may be placed on the fourth supply line (1721d).

[0116] Through this, a supply path of cooling water can be formed by opening and closing a plurality of valves (1730) arranged on a plurality of supply lines (1721). This can be implemented through the cooling control unit (1740) described above with reference to FIG. 3.

[0117] Additionally, the sixth valve (1730f) can be opened and closed by being positioned on the connection side of the inlet line (1722) and the chiller (1710). Through this, the cooling water that has passed through the heat exchanger (1240) provided in the plurality of dispensers (1200) can be re-introduced into the chiller (1710).

[0118] Additionally, as described above through FIG. 2, in the charging device (1000) according to one embodiment of the present invention, a plurality of dispensers (1200) may include a charger (1230) connected to a power cable (1220), and a heat exchanger (1240) may be connected to the power cable (1220).

[0119] That is, as illustrated in FIG. 8, a first power cable (1220a) connected to a first charger (1230a) may be connected to a first heat exchanger (1240a). A second power cable (1220b) connected to a second charger (1230b) may be connected to a second heat exchanger (1240b). A third power cable (1220c) connected to a third charger (1230c) may be connected to a third heat exchanger (1240c). And a fourth power cable (1220d) connected to a fourth charger (1230d) may be connected to a fourth heat exchanger (1240d).

[0120] Through this, the heat generated in the power cable (1220) when charging an electric vehicle can be cooled, thereby ensuring that the power cable (1220) has thermal durability. In addition, as described above, even when rapidly charging an electric vehicle, the power cable (1220) can be cooled.

[0121] In addition, the charging device (1000) according to one embodiment of the present invention can distribute cooling water supplied to a plurality of dispensers (1200) through a cooling module (1700), and can efficiently cool the power cable (1220) even when the user charges for a long time, thereby improving stability.

[0122] In summary, the charging device according to the present invention can increase charging efficiency by distributing power supplied from a power bank to multiple dispensers that charge an electric vehicle. Furthermore, power can be distributed to at least one of the multiple dispensers by controlling multiple switches positioned on a power distribution line connecting multiple power modules and multiple dispensers. Furthermore, by providing a separate cooling module connected to the multiple dispensers and supplying coolant, the dispenser can be miniaturized while efficiently cooling the power cable. Furthermore, the power module and cooling module can be housed in a single housing, thereby ensuring efficient installation space.
