[0024] The high-safety energy storage lithium battery module provided by the present invention is to solve the problem that the existing lithium battery modules in the prior art generate heat during operation, are prone to fire due to improper use, and have great hidden dangers.

[0028] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A high-safety energy storage lithium battery module, wherein the fire extinguishing mechanism 2 is provided with multiple groups, and the fire extinguishing mechanism 2 also includes a guide rod 203 arranged in the box body 1, a baffle 204 is slidably arranged on the guide rod 203, an expansion solid 205 is arranged on the baffle 204, and a barb 206 is arranged on the baffle 204, and the barb 206 and the rubber membrane 202 are adapted to each other, and the guide rod 203 is used to guide the baffle 204 when sliding, and the rubber membrane 202 is initially in a tight state, wherein the output end of the barb 206 is in the rubber membrane 202, and because the lithium battery pack 101 is in the temperature range of 150°C to 450°C, many reactions will occur in the lithium battery pack 101, such as electrolyte and solvent decomposition reaction, negative electrode and adhesive reaction, positive electrode and electrolyte reaction, positive electrode material decomposition reaction, etc., producing A variety of flammable gases are generated, which are prone to fire. The solid 205 (which can be one of 316L stainless steel, aluminum, lead and copper) expands significantly when the solid 205 exceeds 150 degrees. Because the annular cavity 301 is filled with coolant, when the temperature of the lithium battery pack 101 is within the temperature range of 150°C to 450°C, the solid 205 expands and drives the baffle 204 to slide along the guide rod 203, so that the baffle 204 is unfolded. When the baffle 204 is unfolded, the barb 206 is driven to tear the rubber film 202 in a tight state, so that the coolant in the annular cavity 301 enters from the water inlet 201 and falls on the lithium battery pack 101, and the single battery in the lithium battery pack 101 that is about to catch fire is wrapped by condensed water to prevent the occurrence of fire; A placement cavity 207 is provided in the box body 1, and the lithium battery pack 101 and the baffle 204 are both provided in the placement cavity 207.

The holes 2093 on the waste liquid box 2091 in the initial state are in communication with the outside. Compared with directly placing the box body 1 on the ground, the waste liquid box 2091 is arranged at the bottom of the box body 1, which can improve the efficiency of heat dissipation; A transparent window 210 is provided on the top of the box body 1.

Since the transparent window 210 is connected to the box body 1 by bolts, it is convenient for the staff to disassemble the transparent window 210 and replace or inspect the lithium battery pack 101. A U-shaped frame 211 is provided at the bottom of the box body 1, and the waste liquid box 2091 is slidably provided on the U-shaped frame 211. When there is coolant in the waste liquid box 2091, condensed water can be quickly poured out; When one or more of the lithium battery packs 101 are within the temperature range of 150°C to 450°C, the fire extinguishing mechanism 2 is used to isolate one or more of the lithium battery packs 101 that are about to catch fire, and wrap them with condensed water to prevent the occurrence of fire without affecting the batteries in normal use. The leak-proof component 209 prevents the internal pressure of the placement cavity 207 from being too high, which may cause damage to the box body 1, thereby increasing the service life of the product.

[0029] Example 2 further optimizes the high-safety energy storage lithium battery module provided in Example 1.

The condensed water is driven to circulate through the conveying component 308. When the inlet and outlet pipe 3081 rotates, the auger blade 3082 is driven to rotate synchronously, so that the coolant in the annular cavity 301 circulates, and the circulation direction of the coolant is controlled by the rotation direction of the auger blade 3082. The switching component 309 includes a telescopic rod 3091 disposed in the box body 1, the output end of the telescopic rod 3091 is connected to the mounting frame 302, the interior of the telescopic rod 3091 is filled with expansion gas, and a spring 3092 is disposed in the telescopic rod 3091. When the temperature of the lithium battery pack 101 is low, the elasticity of the spring 3092 drives the telescopic rod 3091 to reset, and the expansion gas (which may be one of hydrogen, carbon dioxide, methane and argon) has the characteristic of thermal expansion and contraction; The outer side of the inlet and outlet pipe 3081 is provided with a plurality of strip grooves 3093, and the strip grooves 3093 and the fan blades 304 are adapted to each other. When the temperature of the lithium battery pack 101 is high, the expansion gas in the telescopic rod 3091 expands, and the expansion gas drives the telescopic rod 3091 to expand. The expanded telescopic rod 3091 drives the mounting frame 302, the motor 303 and the fan blades 304 to move synchronously, and at the same time, the fan blades 304 are adapted to the strip grooves 3093, and the inlet and outlet pipe 3081 is driven by the fan blades 304. 1 rotates, and the auger blades 3082 in the inlet and outlet pipes 3081 rotate synchronously, so that the coolant in the annular cavity 301 circulates. When the temperature of the lithium battery pack 101 is low, the characteristics of thermal expansion and contraction of the expanding gas and the elasticity of the spring 3092 drive the telescopic rod 3091 to reset, and the fan blades 304 are separated from the adaptation of the strip grooves 3093. At the same time, the fan blades 304 are aligned with the air cooling cavity 305, so that the lithium battery pack 101 is air-cooled. By switching between air cooling and water cooling, energy consumption can be reduced; The cooling mechanism 3 is used to dissipate heat for the lithium battery pack 101 when it is working normally. The switching component 309 is used to cool the lithium battery pack 101 by air when it is at a low temperature. When the temperature of the lithium battery pack 101 is high, the air cooling is switched to water cooling, thereby reducing energy consumption.

[0030] The use process of the high-safety energy storage lithium battery module provided by the present invention is as follows: When in use, when one or more of the lithium battery packs 101 are in the temperature range of 150°C to 450°C, the expansion solid 205 will expand and drive the baffle 204 to slide along the guide rod 203, so that the baffle 204 is unfolded. When the baffle 204 is unfolded, the barb 206 is driven to tear the rubber film 202 in a tight state, so that the coolant in the annular cavity 301 enters from the water inlet 201 and falls on the lithium battery pack 101, and the lithium battery pack 101 is wrapped by condensed water to prevent the lithium battery pack 101 from catching fire. At the same time, the end of the baffle 204 and the triangular block 208 are The baffle plate 204 is fitted and limited, and the baffle plate 204, the triangular block 208 and the placement cavity 207 form a closed space, wherein the closed space is connected to the annular cavity 301, and the single battery in the lithium battery pack 101 that is about to catch fire is sealed to prevent condensed water entering the closed space from affecting other normal batteries. Because the single battery in the lithium battery pack 101 that is about to catch fire will produce flammable gas, and at the same time, it will mix with condensed water, so that the baffle plate 204, the triangular block 208 and the placement cavity 207 form a closed space with a larger internal pressure, and the rubber plug 2092 is squeezed out by the pressure. Then, the condensed water is discharged from the placement chamber 207 into the waste liquid box 2091, and the condensed water is collected, and at the same time, the pressure inside the placement chamber 207 is prevented from being too high, which may cause damage to the box body 1. When the lithium battery pack 101 is working normally and the lithium battery pack 101 is at a high temperature, the expansion gas in the telescopic rod 3091 expands, and the expansion gas drives the telescopic rod 3091 to expand. The expanded telescopic rod 3091 drives the mounting frame 302, the motor 303 and the fan blade 304 to move synchronously, and at the same time, the fan blade 304 is adapted to the strip groove 3093, and the motor 303 drives the fan blade 30 4 rotates, the fan blades 304 drive the inlet and outlet pipes 3081 to rotate, and the auger blades 3082 in the inlet and outlet pipes 3081 rotate synchronously, so that the coolant in the annular cavity 301 circulates, and the water cooling of the lithium battery pack 101 is realized. When the temperature of the lithium battery pack 101 is low, the characteristics of thermal expansion and contraction of the expanding gas and the elasticity of the spring 3092 drive the telescopic rod 3091 to reset, and the fan blades 304 are separated from the adaptation of the strip grooves 3093. At the same time, the fan blades 304 are aligned with the air cooling cavity 305, so that the air cooling of the lithium battery pack 101 is realized. By switching between air cooling and water cooling, energy consumption can be reduced.
