Abstract

The invention discloses a device for detecting the temperature control function of a sodium-sulfur battery management unit. The device comprises an upper computer, three lamp bulbs and three K-shaped thermocouples. The three lamp bulbs are connected between the input ends and the output ends of three thermal insulation box heating panel heating circuits; the three K-shaped thermocouples are connected to three heating panel temperature measuring terminals respectively; the upper computer is connected to the sodium-sulfur battery management unit and is used for presetting a temperature threshold. The lamp bulbs are used for replacing the heating panel with the lamp bulbs and the temperature control function of the BMU accurately and quickly. The invention also discloses a method for detecting the temperature control function by use of the device for detecting the temperature control function; the method is capable of accurately determining whether the temperature control function of the BMU is satisfied.

Description

technical field [0001] The invention relates to the field of sodium-sulfur battery detection, in particular to the field of temperature control function detection of a sodium-sulfur battery management unit. Background technique [0002] The normal operating temperature range of sodium-sulfur batteries needs to be maintained at 320°C±30°C, so the sodium-sulfur battery module is a high-temperature energy storage system. Multiple sodium-sulfur battery cells for energy storage are placed in a dedicated mechanical electrical box through a specific series-parallel connection, and the battery management system is used to manage the operation and management of the sodium-sulfur battery module, which is responsible for the detection of the current and voltage of the sodium flow battery, SOC ( battery state of charge) estimation, overall failure analysis, judgment and online alarm to ensure the normal charging and discharging of sodium-sulfur batteries. [0003] The battery managemen...
