Embodiment 1

[0020] See figure 2 and image 3 , figure 2 An energy storage of the present invention, the temperature control system of the converter of FIG communication connection control method; image 3 The present control flowchart of an inventive method for temperature control system controlling the storage converter, the present embodiment discloses a method of controlling the temperature control system accumulator converter, the converter including an energy storage, the energy storage management system temperature and for accumulator battery converter temperature adjustment of the adjusting means, the control method further comprising: operating state storage converter operation state detection module detects accumulator converter, the working state detecting module detects that the operation state is sent to the energy management system storage,

[0021] When the accumulator is in operation the converter, the energy storage device is an energy management system for the temperature adjus...

Embodiment 2

[0025] Since a time accumulator battery converter comfort temperature is between 18 ℃ to 28 ℃, in the present embodiment, when the storage management system determines the energy accumulator converter is in operation, the cooling provided The lower limit temperature T1 is 18 ℃, refrigeration sensitivity 10 ℃; when the storage management system determines the energy accumulator converter is in operation, the upper limit of a heating temperature T2 is 28 ℃, heat sensitivity of 10 ℃.

[0026]When the storage converter is in operation and the temperature adjustment device detects that the temperature is higher than 28 ° C, the temperature adjustment device automatically turns the cooling, when the temperature adjustment device detects that the temperature is lower than 18 ° C, the temperature adjustment device is automatically turned off; When the storage converter is in operation and the temperature adjustment means detects that the temperature is below 18 ° C, the temperature adjust...

Embodiment 3

[0028] Suitable storage temperatures in non-working states between 5 ° C and 35 ° C,

[0029] In the present embodiment, when the energy storage energy management system determines that the storage converter is in a non-operating state, the cooling temperature limit is 25 ° C, and the refrigeration sensitivity is 10 ° C;

[0030] When the storage converter is in a non-operating state and the temperature adjustment device detects the temperature above 35 ° C, the temperature adjustment device automatically turns the cooling, when the temperature adjustment device detects the temperature of the temperature below 25 ° C, the temperature adjustment device automatically shuts down .

Abstract

The invention discloses a control method for a temperature control system of an energy storage converter, which comprises the following steps of: detecting the working state of the energy storage converter through a working state detection module of the energy storage converter, and adjusting the temperature of a temperature adjusting device according to the environment temperature of the working state of a battery when the energy storage converter is in a running state; carrying out heating and refrigerating control on the temperature adjusting device according to the refrigerating temperature lower limit and the heating temperature upper limit of the normal working state temperature range of the battery; and when the energy storage converter is in the non-operating state, adjusting the temperature of the temperature adjusting device according to the storage temperature requirement of the battery in the non-operating state. According to the invention, on the basis of detecting and distinguishing the working state of the energy storage converter in the energy storage system, different temperature range control is adopted for the temperature control system, the requirements for the environment temperature of the working state and the storage temperature of the non-working state of a battery are met, and the power consumption of the temperature control system is reduced; therefore, the overall efficiency of the energy storage system is improved.

Description

Technical field [0001] The present invention relates to storage control technology, temperature control flow control system and particularly to a method for the storage variable. Background technique [0002] Conventional energy storage systems, such as figure 1 , Since the operating characteristics of lithium batteries, the basic temperature control system using the thermostat cooling / heat battery is placed at about ambient temperature control 23 ℃, consider a temperature regulating refrigeration apparatus hysteresis 5 ℃, the battery is located temperature is between 18 ℃ ~ 28 ℃. Suitable temperature and the battery is stored in a non-operating state is between 5 ℃ ~ 35 ℃. Therefore it does not distinguish between a state in which the battery will cause a certain extent, large power loss, can not be fine management of the storage temperature control system, thereby reducing the overall efficiency of the energy storage system. [0003] For this purpose, on the basis of need, di...
