Detailed Description

The present disclosure will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the present disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Lithium battery equipment is placed in the existing energy storage container more, and the lithium battery has the characteristic of easy ignition, so that the existing energy storage container generally has the risk potential hazard of ignition. At present, most of universal energy storage containers are large-size containers such as 20 or 40, on one hand, the large-size containers occupy large area and are complex to hoist and transport, on the other hand, large-capacity battery equipment is often placed inside the large-size containers, once a fire breaks out, short-circuit energy of the whole system is huge, and great harm is easily caused to all equipment in the containers and the surrounding environment.

The embodiment of the disclosure provides a modular energy storage container which is formed by splicing container modules with fixed sizes serving as basic units. Wherein, the container module is inside to be separated into two at least compartments by the baffle, and this compartment is used for placing energy storage equipment. It should be noted that although the container modules are mainly used for splicing into large-sized modular energy storage containers, one container module can also be used as an energy storage container alone. In one possible implementation, the separator includes a metal plate and a flame retardant insulating plate. Wherein, the metal sheet can be the steel sheet that the field is commonly used, and fire-retardant insulation board can be fire prevention rock wool board. For example, the steel plate can be placed between two fireproof rock wool plates to form a partition plate with a three-in-one structure.

In one possible implementation, the fixed-size container module may be a 5-foot container.

In one possible implementation, the container module interior may be divided into two compartments by a partition. As shown in fig. 1, the modular container may be divided into two opposing compartments by a partition.

In one possible implementation, the outer shell of the container module and all the inner walls of at least two compartments are provided with a fire-resistant material, i.e. the outer shell of the modular container and all the inner walls of each compartment may be provided with fire-resistant insulation panels to prevent the spread of a fire in case of fire.

In a possible implementation, the two compartments comprised by the container module are each provided with a door, the door of each compartment being outwardly opening. Set up to the outside through the door with the compartment and open a door operation outside, the staff to need not at the inside reservation passageway of container, can practice thrift the inner space of container, conveniently place energy storage equipment.

Through setting up the container module into the small-size container, separate the inside space of container module, and place the relevant equipment of energy storage such as battery System or PCS equipment (Power Control System, energy storage converter) of corresponding volume according to actual need in each compartment, in case the conflagration breaks out, the modular compartment design has reduced battery capacity, can reduce the danger level of conflagration, and through all setting up refractory material around the compartment, can win the precious time for fire Control and fault handling. In addition, the fire hazard can be limited in the compartment by arranging the fireproof materials around the compartment, and the equipment safety of other compartments cannot be influenced when any one compartment is in fire hazard, so that the fire hazard level can be greatly reduced, and the equipment loss in the fire hazard can also be reduced.

In this possible implementation, the fire-retardant insulating panels around the compartment are replaceable, and the aged or damaged fire-retardant insulating panels can be quickly replaced by staff, after a period of use, or after a fire.

The embodiment of the disclosure also provides a bottom support, which is used for splicing the container modules in the above embodiments through the bottom support to form a large-size container. As shown in fig. 2, the present embodiment provides that the bottom support 100 includes a bolt 200, and the bolt 200 is used to connect the modular container 300 to the bottom support 100 through the bolt 200. Wherein the bottom of each modular container is provided with bolt holes (not shown) corresponding to bolts 200. Each two adjacent modular containers may also be fixedly connected by a connecting bolt 400. In addition, the bottom support can be provided with a through hole 500. The cable connections between different modular containers may be arranged in the shoe, connecting the cables to different modular containers through the through holes 500, forming an integrated energy storage system.

In one possible implementation, 4 5 modular containers may be connected to the same base to form a 20 full size container, or 8 5 containers may be connected to the same base to form a 40 full size container. In practical application, staff can flexibly select the number of suitable 5-foot containers and the bottom supports with corresponding specifications to splice according to actual needs. Through the bottom support for splicing the container modules, workers can splice the container modules rapidly on the working site according to actual needs to form a large-size container with required size, and the problems of large occupied area, heavy weight and inflexible configuration of the conventional large-size container can be solved. In addition, the bottom support and the container module can be detached, and workers can select whether to use the bottom support for splicing according to actual requirements.

In one possible implementation, when transporting a plurality of container modules, for the convenience of transportation, the plurality of container modules may be first connected to the base and then disassembled or re-installed as needed when arriving at the destination.
