Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention is further described below with reference to examples.
Examples: referring to fig. 1 to 7, a high protection energy storage battery module includes an energy storage battery module 1 composed of a plurality of battery cells 11 arranged at equal intervals, a battery fixing assembly 2 for fixing each battery cell 11, and a heat dissipation performance adjusting assembly 3 for indirectly and synchronously adjusting the spacing of each battery cell 11 through the battery fixing assembly 2 so that the energy storage battery module 1 is at an optimal working temperature.
One of the basic concepts of the present invention is: the corresponding type of battery cell 11 (one of ion battery, lead-acid battery, nickel-hydrogen battery, lithium polymer battery, etc.) is selected according to the need, taking lead-acid battery as an example, then T1 is 20 ℃, T2 is 30 ℃, the optimal working temperature is 25 ℃, the heat preservation temperature T4 (the temperature value that can not maintain the side surface temperature to reach the optimal working temperature when the battery cell 11 is in normal working efficiency) is set to 0 ℃, in addition, the heat dissipation performance adjusting component 3 is connected with a temperature management system in the prior art, the temperature management system is used for monitoring the side surface temperature and the environmental temperature of the battery cell 11, and the temperature can be monitored in real time by setting a temperature sensor.
The basic principle of performing heat dissipation performance is that the air flow space is larger or smaller by adjusting the interval between the battery cells 11, specifically: 1. when the temperature of the side surface of the battery cells 11 is higher than the optimal working temperature and the ambient temperature is higher than the heat preservation temperature, the heat dissipation performance is not enough without considering the ambient temperature, and the space between the battery cells 11 is increased through the heat dissipation performance adjusting component 3 so as to improve the heat dissipation performance; 2. when the side surface temperature is lower than the optimal working temperature and the ambient temperature is higher than the heat preservation temperature, the heat dissipation performance is excessively large without considering the ambient temperature, and the interval between the battery cells 11 is reduced by the heat dissipation performance adjusting assembly 3 to weaken the heat dissipation performance. The side surface temperature of the battery cell 11 is always maintained near the optimal operating temperature, improving the operating performance of the battery cell 11.
The second basic concept of the invention is as follows: when the environmental temperature is too low, the battery cells 11 are tightly arranged and cannot maintain the optimal working temperature, so the heat preservation temperature T4 is additionally arranged, namely, when the environmental temperature is lower than the heat preservation temperature, heat preservation measures are needed, and when the working efficiency of the battery cells 11 is higher than the normal working efficiency, heat dissipation is needed to be considered, so the heat preservation cover 51 with changeable heat conductivity according to the needs is designed, and the principle is that: under the non-vacuum condition of atmospheric pressure, heat conduction mainly transfers heat through collision between atoms or molecules inside the solid substance, under the vacuum condition, as no gas molecules participate in heat transfer and conduction, the efficiency of heat conduction can be obviously affected by changing the vacuum degree.
Therefore, in addition, when the side surface of each battery cell 11 contacts, the temperature of the side surface is lower than the optimal working temperature, and the temperature of the environment is lower than the insulation temperature, the insulation component 5 is covered outside the battery cell 11 and used for insulation, specifically, referring to fig. 1, 5 and 7, the insulation component 5 comprises an insulation cover 51 which is arranged in a hollow mode, two air holes are arranged on the insulation cover 51, one air hole is connected with a vacuum pump 52, the other air hole is connected with a switch valve 53 through a one-way valve, the vacuum pump 52 and the switch valve 53 are in signal connection with a temperature management system, the air inside the battery cell 51 is sucked by the vacuum pump 52, the external air can enter the insulation cover 51 through opening the switch valve 53, and the insulation cover 51 is required to be strong enough to maintain the shape and not influenced by air pressure.
Further, a connection notch 54 is provided at the center of the upper end of the heat insulation cover 51 in order to provide a space for connecting adjacent battery cells 11 in series or parallel. In order to avoid the condition that the heat dissipation performance adjustment of the battery cell 11 is affected by the exposure of the upper and lower surface portions of the battery cell 11, the upper and lower surfaces of the battery cell 11 are subjected to heat insulation treatment.
For the fixed arrangement of the battery cells 11, reference is made to fig. 3 to 4: 1. two fixed plugboards 12 are fixedly arranged at the lower ends of the battery monomers 11, and plugholes 13 are formed in the fixed plugboards 12; 2. the battery fixing assembly 2 comprises a supporting seat 21 with a box-shaped structure, the width of the supporting seat 21 is smaller than that of the battery monomers 11, so that the battery monomers 11 can be arranged in a mutually tight fit mode, a slot 211 capable of being in plug-in fit with the fixing plug board 12 is formed in the upper end of the supporting seat 21, a first rotating shaft 25 is arranged in the supporting seat 21 in a rotating mode, a first bidirectional thread is arranged on the outer surface of the first rotating shaft 25, a second sliding plate 23 is connected with the first bidirectional thread in a symmetrical mode in a threaded mode, the second sliding plate 23 is connected with the supporting seat 21 in a sliding mode, and a plug rod 24 capable of being plugged into the plug hole 13 is fixedly connected to one side, opposite to the opposite side, of the second sliding plate 23. When each battery cell 11 needs to be fixed, the fixing plugboard 12 at the lower end of the battery cell 11 is inserted into the alignment slot 211 and is placed above the supporting seat 21 and supported, and the first rotating shaft 25 is driven to rotate under the influence of external force (described below), so that the second sliding plates 23 under the limiting condition move oppositely to drive the plugboard 24 to be in plug-in fit with the plughole 13 at the corresponding position, and the fixing of the battery cell 11 is completed.
