5. The cooling system of claim 1 , wherein the arrangement includes a cover defining a plurality of slots to correspondingly receive the plurality of electrical components therethrough and have the cover wrap around and provide a sealing around each electrical component, the sealing restricting the air flow directed around the plurality of electrical components from being redrawn into the cooling system.

6. A containerized energy storage system, comprising:

a plurality of electrical components;

a container to house the plurality of electrical components, the container including an inlet port to draw air into the container and an exhaust port to release air out of the container;

a cooling system for the plurality of electrical components, the cooling system including:

a blower to generate an air flow;

a platform to mount the plurality of electrical components, the platform defining a plurality of passages; and

an arrangement including a plenum extending between the blower and the platform to direct the air flow towards and around the plurality of electrical components through the plurality of passages, wherein the plenum includes:

a primary chamber to receive the air flow from the blower; and

a secondary chamber defining a structural section diverging outwardly and away from the primary chamber.

7. The containerized energy storage system of claim 6 , wherein

the secondary chamber directs air flow towards the platform.

8. The containerized energy storage system of claim 7 , wherein

the primary chamber includes a base and a plurality of walls positioned upright with respect to the base, the plurality of walls and the base surrounding a volume of the primary chamber, and

the structural section of the secondary chamber includes a first sidewall and a second sidewall disposed oppositely to each other, each of the first sidewall and the second sidewall being inclined with respect to corresponding walls of the plurality of walls of the primary chamber to define the structural section diverging away and outwardly from the primary chamber towards the platform, wherein

the first sidewall and the second sidewall respectively define a first angle and a second angle with respect to the corresponding walls, the first angle being equal to the second angle.

9. The containerized energy storage system of claim 7 , wherein the arrangement includes:

a diffuser disposed between the secondary chamber of the plenum and the platform, the diffuser including a perforated plate defining a plurality of air flow apertures to diffuse the air flow received from the secondary chamber of the plenum and uniformly distribute the air flow towards each electrical component mounted on the platform.

10. The containerized energy storage system of claim 9 , wherein the plurality of electrical components are arranged in a two-dimensional array on the platform, and wherein the plurality of air flow apertures are disposed at a uniform offset with respect to the two-dimensional array of the plurality of electrical components.

11. The containerized energy storage system of claim 6 , wherein

the platform includes a plurality of spaced apart beams arranged in a planar configuration,

a plurality of links arranged across the plurality of spaced apart beams to define a grid formation with the plurality of spaced apart beams, the plurality of links is configured to mount the plurality of electrical components thereon to arrange the plurality of electrical components on the platform, and

the plurality of links arranged across the plurality of spaced apart beams defines the plurality of passages for the air flow to pass therethrough and reach up to the plurality of electrical components.

12. The containerized energy storage system of claim 6 , wherein the arrangement includes a cover defining a plurality of slots to correspondingly receive the plurality of electrical components therethrough and have the cover wrap around and provide a sealing around each electrical component, the sealing restricting the air flow directed around the plurality of electrical components from being redrawn into the cooling system.

13. The containerized energy storage system of claim 6 , wherein each electrical component of the plurality of electrical components includes a core and an outer sheath surrounding and defining a clearance between the outer sheath and the core, and wherein the plenum directs the air flow to pass through the clearance associated with each electrical component.

14. A method for cooling a plurality of electrical components, the method comprising:
