Problems solved by technology

[0003] However, after a series of project verifications, although the efficiency of lithium battery energy storage products is higher than that of other energy storage systems, there is still a large energy loss. In addition to inevitable losses such as internal resistance, the power consumption of system thermal management has a particularly obvious impact on system efficiency
Since the battery will generate a lot of heat during charging and discharging, in order to ensure the operation of the battery within the optimum temperature range, ensure the normal operation of the system, improve product reliability, and reduce battery life attenuation, the existing lithium battery energy storage container system is basically equipped with There is a high-power industrial air conditioning system (the power of an ordinary industrial air conditioner is generally tens of kilowatts), and the overall switch control of the industrial air conditioner is performed according to the battery temperature. This design leads to extremely high power consumption of the system thermal management, which seriously affects the product revenue

Abstract

The invention provides an energy storage container temperature control system and a temperature control method. The temperature control system comprises an air inlet part, an air outlet part, a control part and an air duct part in a box body, and an external air inlet module and an air outlet of an air conditioner are jointly used as an air inlet part. The external air inlet module is composed ofa first electric shutter installed on the air inlet channel and a plurality of air inlet fans. An external air outlet module and an air inlet of each air conditioner jointly serve as an air outlet part, the external air inlet module is composed of a second electric shutter installed on an air outlet channel and a plurality of air outlet fans, an air outlet of each air conditioner is communicated with an air inlet of an air duct part, and an air inlet of each air conditioner is communicated with an air outlet of the air duct part. The system power consumption is greatly reduced while the battery operation storage temperature is ensured, the working efficiency of the energy storage system is effectively improved, and the product income is improved; and meanwhile, the air-conditioner utilization rate is reduced, and the air-conditioner service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric energy storage, and in particular relates to an energy storage container temperature control system and a temperature control method. Background technique [0002] In recent years, with the increasing frequency regulation, demand regulation, peak shaving of power plants, and the demand for wind and new energy, the demand for power storage system products is increasing. Among them, lithium battery energy storage products are characterized by their high performance, long life, clean and non-toxic. Advantages such as pollution become the first choice. [0003] However, after a series of project verifications, although the efficiency of lithium battery energy storage products is higher than that of other energy storage systems, there is still a large energy loss. In addition to inevitable losses such as internal resistance, the power consumption of system thermal management has a particularly obviou...
