The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The present inventors have found that at least the following problems exist during the use of existing energy storage devices:
1. many of the system designs are collected by using a traditional battery management system, and the system is unified with a battery inverter to perform interaction, so that the arrangement of the wire harness and the structure is complex.
2. Many energy storage containers are simpler in design of a fire protection system, and only one rain spraying device is arranged in a large box, so that after a fire occurs in energy storage, a fire source cannot be completely extinguished, and the spread of the fire cannot be effectively prevented.
3. For the energy storage device with the highly integrated battery pack inside, many existing heat dissipation schemes only add a fan on the box body of the device to dissipate heat, and the design cannot well dissipate heat of the energy storage system.
In view of the above problems, as shown in fig. 1 and 2, an embodiment of the present invention provides a container type energy storage device. As shown in fig. 1, the container type energy storage device comprises a container body 1 and an energy storage inverter 12 with an information acquisition function, wherein a heat dissipation channel 2 and an energy storage pile 3 are arranged in the container body 1, a cooling structure 5 is further arranged on the container body 1, and the cooling structure 5 is communicated with the heat dissipation channel 2; the container-type energy storage device further comprises a fire protection system 8 for providing fire extinguishing medium for the energy storage stack 3; the energy storage inverter 12 is electrically connected to the energy storage stack 3.
The cooling structure 5 blows a heat radiation medium into the container body 1 through the heat radiation channel 2, thereby realizing the cooling of all devices in the container body 1, mainly the energy storage stack 3. The fire extinguishing system 8 mainly performs fire extinguishing treatment on the energy storage pile 3 to avoid the expansion of fire. The energy storage inverter 12 performs conversion between alternating current and direct current.
In order to effectively prevent the spread of fire, as shown in fig. 3, the energy storage stack 3 includes an energy storage structure including at least one battery cluster 6, and an electric control structure, and each of the battery clusters 6 includes at least one battery pack electrically connected to the energy storage inverter 12. In practice, the locations at which fires may occur are mainly the inside of the battery pack, the outside of the battery pack (i.e., the inside of the battery cluster 6), and the outside of the battery cluster 6, so that when setting up a specific fire extinguishing location for the fire extinguishing system 8, it is considered to set up corresponding fire extinguishing equipment at each of these locations at which fires may occur.
In a possible embodiment of the fire protection system 8, the fire protection system 8 comprises a master controller and at least three fire extinguishing medium release mechanisms, wherein the master controller is in communication connection with both the energy storage inverter 12 and the energy storage stack 3, and the fire extinguishing medium release mechanisms are in communication connection with the master controller. The master controller is used for collecting the smoke and temperature from the energy storage pile 3, and makes a starting or stopping instruction for adjusting the fire extinguishing medium releasing mechanism after analysis and judgment, so that the fire extinguishing position is accurately extinguished.
In practical applications, as to how the overall controller collects the fumes and temperature conditions coming from the energy storage stack 3, as shown in fig. 5, at least one compound sensor is provided, for example, in the possible location of the fire: to realize fire extinguishment in the battery packs, a composite sensor can be respectively arranged at the front end and the rear end of each battery pack, the composite sensor is used for measuring the temperature and the pressure in the battery pack, and the composite sensor is in communication connection with a master controller; wherein each of the multiple sensors is capable of simultaneously sensing temperature and pressure.
In one possible embodiment, the specific arrangement of the fire extinguishing medium discharging mechanism may be as follows:
the fire extinguishing medium released by at least one fire extinguishing medium releasing mechanism reaches the inside of the battery pack and the fire extinguishing medium released by at least one fire extinguishing medium releasing mechanism reaches the inside of the battery cluster 6, and the fire extinguishing medium released by at least one fire extinguishing medium releasing mechanism reaches the outside of the battery cluster 6. The interior of the battery pack, the interior of the battery cluster 6 and the exterior of the battery cluster 6 are respectively subjected to accurate fire extinguishing.
In order to eliminate the fire in the battery pack to the greatest extent, at least two fire extinguishing medium release mechanisms can be arranged for the number of the fire extinguishing medium release mechanisms at the position, and after one fire extinguishing medium release mechanism is used for extinguishing a fire, if smoke is detected to be higher than a set value, the other fire extinguishing medium release mechanism is started to continue extinguishing the fire (namely, secondary fire control), so that the fire in the battery pack is eliminated to the greatest extent, and larger loss caused by expansion of fire is avoided.
As shown in fig. 5, the overall controller and energy storage inverter 12 maintain data sharing in real time. Once a fire condition occurs in a certain battery pack, the master controller can immediately control the fire control gas control valve, the electromagnetic valve of the loop is opened, fire control gas is accurately conveyed to the battery pack with the fire condition through the fire control gas pipeline in the fire control gas device to extinguish the fire condition, meanwhile, the master controller can report the energy storage inverter 12 and light the inner and outer fire control indicator lamps and the alarm, and at the moment, a fire fault of a platform can be reported, and the power output of the battery is cut off. When the fire-fighting gas is consumed, if the fire condition of the target battery pack is not controlled, the liquid control valve can open the electromagnetic valve in a targeted mode, fire-fighting water is filled into the battery pack through the fire-fighting pipeline instantly, and when the battery pack is filled with water, air is isolated, and the aim of completely extinguishing fire is achieved.
When fire spreads to the outside of a single battery pack, as shown in fig. 6, smoke detectors are arranged above each battery cluster 6, when the detectors detect abnormality, a master controller is reported, and the master controller confirms to open the sub-control valves on the corresponding battery clusters 6 according to the smoke positions, so that the delivery of fire extinguishing gas or liquid is realized, and the aim of fire extinguishing is fulfilled. When a fire propagates outside the battery cluster 6, a fire extinguishing medium discharging mechanism for extinguishing the fire is started.
In a possible embodiment, each of the fire extinguishing medium discharging mechanisms includes a smoke detector, a fire extinguishing medium reservoir, and a valve disposed on the fire extinguishing medium reservoir, the smoke detector and the valve being in communication with the master controller.
In a possible embodiment, the specific kind of fire extinguishing medium in each fire extinguishing medium discharging mechanism may be the same or different, and is specifically selected according to the performance of the energy storage material inside the battery pack.
