Example Embodiment

[0028] The present invention is further illustrated by way of examples, but will not be limited to the scope of the embodiments.

[0029] Such as figure 1 As shown, the present invention discloses an internal heat exchange cycle control method in which the power transmission station is disclosed, wherein the internal heat exchange cycle control method of the power-on power station includes the following steps:

[0030] Step S101, the normal temperature range of the battery pack and the charging module is preset;

[0031] Step S102, the temperature of the charging module and the battery pack is collected, and the battery pack and / or the charging module will be heat excited according to the acquisition temperature;

[0032] Step S103, in the normal temperature range, the heat transfer medium flows through the battery or charging module in the power station.

[0033] In the present invention, the charging module corresponds to the battery separation setting, which reduces the conce...

Abstract

The invention discloses an internal heat exchange cycle control method for a battery swap station. The method comprises the following steps: respectively presetting normal temperature ranges of a battery pack and batteries respectively acquiring the temperatures of charging modules and the battery pack, and performing heat exchange control on the battery pack and/or the charging modules according to the acquired temperatures; and in the normal temperature range, enabling a heat exchange medium circularly to flow through the batteries or the charging modules in the battery replacing station. The charging modules are separately arranged, so that heat concentration is reduced. Heat generated by charging of the charging modules is uniformly dissipated into the open space, and the temperature of the whole battery swap station is controlled within a reasonable range by means of natural heat dissipation. Under the condition of low temperature, the heat generated by the charging modules is dissipated, and the heat taken away by the heat exchange medium can be balanced with the heat of the batteries, so that the temperature of the batteries is improved, and the condition that the charging efficiency of the battery is reduced and even the battery cannot be charged in a low-temperature state is avoided.

Description

technical field [0001] The invention relates to a method for controlling an internal heat exchange cycle of a power exchange station. Background technique [0002] At present, the chargers in the power station are installed in a traditional cabinet, and the power is distributed in a centralized manner. These charging cabinets are centrally arranged in a separate space of the entire power exchange station (this space is used to arrange power distribution and air conditioning devices) and the battery rack is arranged in another space of the power exchange station, which is called a charging room. Each charger in the charging cabinet outputs 2 DC output power lines and a set of charging control lines (including CAN communication between the charger and the battery and other control lines). The length of these lines depends on the number and layout of batteries in the station. , and its length is between 3-20 meters. [0003] Since the alternating current is input into the cha...
