Description
Technical Field
The invention belongs to the technical field of battery thermal management experimental equipment, and relates to a battery module experimental box device which is used for simulating the general working condition and the extreme working condition of a battery module during working.
Background
Currently, batteries are favored by all countries in the world as novel environmental-friendly power energy sources. However, in the actual operation process of certain areas, some severe environmental conditions, such as wide outdoor temperature variation range from-40 ℃ to 40 ℃, can be met. In coastal areas, the external atmosphere is relatively humid, and the box body is corrosive. During the charge and discharge of the battery, a large amount of heat is generated due to the electrochemical reaction and the internal resistance, so that the temperature is increased. Excessive temperature may cause gas escape or corrosion of the battery, and even thermal runaway may occur in severe cases, so that the electrolyte is decomposed to generate a large amount of gas, resulting in explosion of the battery due to excessive pressure, and aged battery is more likely to cause uneven temperature distribution. Therefore, thermal management of the battery is required. Because of the good cooling effect of the liquid medium, thermal management systems employing liquid media have evolved rapidly in recent years. This patent has designed a sealed box that adopts liquid cooling heat dissipation mode, keeps warm adiabatic completely.
