Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] See Figure 1-3 , the present invention provides a charging pile 100 , which includes a coolant heat exchange device 110 . The coolant heat exchange device 110 includes a heat exchange pipeline 111 , a coolant output pipe 212 and a coolant input pipe 222 connected to the heat exchange pipeline 111 . When the charging pile 100 is in operation, the coolant output pipe 212 and the coolant input pipe 222 are used to communicate with the cooling pipeline of the vehicle battery 30 respectively, so that the heat exchange pipeline 111 and the vehicle battery 30 The cooling lines fo...

Abstract

The invention provides a charging pile. The charging pile comprises a cooling-liquid heat exchanging device. The cooling-liquid heat exchanging device comprises a heat exchanging pipe, a cooling-liquid output pipe and a cooling-liquid input pipe, wherein the cooling-liquid output pipe and the cooling-liquid input pipe are connected with the heat exchanging pipe, and are used for being communicatedwith a vehicle-mounted battery cooling pipe respectively, and thus a loop is formed by the heat exchanging pipe and the vehicle-mounted battery cooling pipe. Through the loop of the cooling liquid pipe, and heating and cooling of a full-electric-vehicle battery pack can be achieved through the cooling-liquid heat exchanging device of the charging pile so that a vehicle-mounted battery can be charged in the best temperature range. When a full electric vehicle is charged, it can guarantee that a power battery is charged at the optimum temperature through the charging pile according to the environment temperature, the present temperature of the power battery and different charging requirements of the power battery, the charging speed of the charging pile is increased accordingly, and the charging time of the charging pile is shortened.

Description

technical field [0001] The invention relates to the field of power battery charging, in particular to a charging pile. Background technique [0002] With the development of science and technology and new energy, pure electric vehicles have been more and more popularized and applied due to their unique advantages. The internal resistance of the power battery of pure electric vehicles is low, and the temperature rise of the battery is very small under the operating conditions of the vehicle. If the initial temperature of the battery is controlled within the appropriate range, the final temperature of the battery will not be too high, thus ensuring the durability and reliability of the battery. safety. [0003] With the user's requirements for charging time, fast charging and super fast charging functions have become the future development trend. High temperature and low temperature will affect the safety and durability of the battery. Under fast charging conditions, the prob...
