Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044]At present, when the battery is charged in the high temperature season, the battery will have the problem of overcharging; when the battery is charged in the low temperature condition, the charging acceptance of the battery is lower. There will still be problems for a long time. Based on this, a charging pile, charging control method and device provided by the embodiment of the...

Abstract

The invention provides a charging pile, a charging control method and device. A connecting cable in the charging pile comprises at least one temperature control pipeline; two air inlet ports of the temperature control pipe are connected with a heating module and a cooling module respectively; the end surface of the connecting cable is provided with a temperature sensor for detecting a temperature value of the surface of an accumulator; a control module is used for generating cooling control signals or heating control signals according to the temperature value; the heating module is used for heating the air in a preset cavity according to the heating control signals; the cooling module is used for cooling the air in the preset cavity according to the cooling control signals. A fan is arranged at the air inlet and used for blowing the air in the preset cavity so that the air can pass through a temperature control pipeline, and then acts on the outer wall of the accumulator to reach the technical effects that when the accumulator in an electric car is charged in a high temperature season, the overcharging problem is avoided; in a low temperature environment, the charging receiving capacity of the accumulator can be improved, and the charging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging pile, a charging control method and a device. Background technique [0002] At present, electric vehicles use batteries to provide electric energy for the drive motor, and the drive motor converts the electric energy of the power supply into mechanical energy, and then drives the wheels and working devices through the transmission device or directly. [0003] However, on the one hand, when charging the battery in the high temperature season, due to the increase of the temperature of the battery, the activity of each active material in the battery increases, the oxygen evolution potential of the positive electrode decreases, and the oxygen evolution potential of the negative electrode also decreases (negative value decreases). The problem of overcharging occurs; on the other hand, when charging the battery at low temperature, due to the decrease in the activity o...
