The present invention provides a thermal management and automatic fire-extinguishing system of a vehicle battery, used for managing the vehicle battery in a hybrid vehicle or an electric vehicle, including: fire-extinguishing packages which are adjacent to or in contact with the vehicle battery, wherein the fire-extinguishing package is filled with a fire-extinguishing agent; and the fire-extinguishing package is configured to be opened when the temperature of the vehicle battery is higher than a preset temperature, so that the fire-extinguishing agent can be released and then filled into a space where the vehicle battery is located, thereby achieving the effects of automatic combustion prevention and fire extinguishing of the vehicle battery, effectively protecting the vehicle battery and the whole vehicle, reserving more escape time for passengers and improving the safety of the vehicle. On the whole, the thermal management and automatic fire-extinguishing system of the vehicle battery of the present invention is simple and reliable in structure, low in cost and strong in universality, and can be directly mounted on the vehicle without reforming the existing vehicle battery cooling system.

1. A thermal management and automatic fire-extinguishing system of a vehicle battery, used for managing the vehicle battery in a hybrid vehicle or an electric vehicle, comprising: fire-extinguishing packages which are disposed adjacent to or in contact with the vehicle battery, and filled with a fire-extinguishing agent;wherein the fire-extinguishing packages are configured to be opened when the temperature of the vehicle battery is higher than a preset temperature, so that the fire-extinguishing agent can be released and then filled into a space where the vehicle battery is located;wherein the fire-extinguishing packages comprise an upper fire-extinguishing package and a lower fire-extinguishing package, the upper fire-extinguishing package wholly covers the upper surface of each vehicle battery or a battery module composed of the vehicle batteries, and the lower fire-extinguishing package wholly covers the lower surface of each vehicle battery or the battery module composed of the vehicle batteries;wherein the upper fire-extinguishing package and the lower fire-extinguishing package are communicated with each other;wherein the upper fire-extinguishing package is connected with a pump in parallel, the fire-extinguishing agent in the upper fire-extinguishing package, which is pumped by the pump, can heat or cool the battery module, and the lower fire-extinguishing package is connected with the pump in parallel, and the fire-extinguishing agent in the lower fire-extinguishing package, which is pumped by the pump, can heat or cool the battery module; andwherein the system further comprises an upper cover and a lower cover, which are disposed at a battery package box body, the upper fire-extinguishing package is directly connected between the battery module and the upper cover, and the lower fire-extinguishing package is directly connected between the battery module and the lower cover. 2. The system of claim 1, wherein the material of at least a part of the upper fire-extinguishing package is plastic or resin, and when the temperature of the vehicle battery is higher than the preset temperature, the at least a part of the upper fire-extinguishing package is heated by the vehicle battery into a fluid state, so that the fire-extinguishing agent can be released and then filled into the space where the vehicle battery is located. 3. The system of claim 2, wherein the melting point of the material of the at least a part of the upper fire-extinguishing package is selected within a range of 85-95° C., and the melting point of the material of the lower fire-extinguishing package is higher than the melting point of the material of the at least a part of the upper fire-extinguishing package. 4. The system of claim 2, wherein the plastic is EVA plastic, and the resin is an ABS/PC alloy. 5. The system of claim 1, wherein the fire-extinguishing agent is silicone oil or transformer oil. 6. The system of claim 1, further comprising an insulating layer arranged on a circuit connecting plate between the battery modules and/or on a connecting wire between the battery modules and electric elements. 7. The system of claim 6, wherein the insulating layer is made of acrylic resin.
