Battery & Charger Enclosures

Custom-Built NEMA 1, 3R and 12 Enclosures

Exponential Power designs and builds custom DC enclosures for battery systems and/or chargers. A typical cabinet integrates batteries, racking and chargers into an indoor (NEMA 1 or 12) or outdoor (NEMA 3R) rated enclosure. There are many different options and accessories available, making every system unique and built to your site-specific needs. They can be constructed with batteries, battery/charger combinations, and even DC distribution panels. Batteries can be installed on pull-out drawers or fixed shelves.

Typical Features

  • Carbon steel (0.104 – 0.125″)
  • ANSI-61 gray powder coated finish
  • Continuously welded and ground smooth seams
  • Lifting eyes for easy handling
  • Concealed door hinges
  • Key / Padlocking handle
  • 3-point locking mechanism
  • Body stiffeners
  • Oil resistant gasket
  • Ground stud on door
  • Print pocket provided on door
  • Provision for mounting LED light

Typical Industry Standards

  • NEMA Type 1, 3R, 12
  • UL Listed Type 1, 3R, 12
  • CSA Type 1, 3R, 12
  • IEC 60529

NEMA Type 1 – Enclosures are for indoor use to provide a degree of protection to personnel against access to hazardous parts and to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt). This is a basic indoor cabinet that will include venting for batteries.

NEMA Type 3R – Enclosures are for indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure. This is a typical outdoor cabinet that will require rain hoods for the vents.

NEMA Type 12 – Enclosures are for indoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and circulating dust, lint, fibers, and flyings); and to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing). This cabinet will require NEMA 12 vents and/or cooling fans.

NEMA1 grill & washable aluminum filter kit – Stainless steel grill with thumb screws. Available in 6″ and 10″ sizes.

Charger subpanel and charger installation – Full or half size subpanels can be installed inside the enclosure to mount the charger and other equipment. This feature is common when a charger is pre-installed inside an enclosure. The subpanel typically mounts to the sides of the cabinets and can telescope towards the front or back of the cabinet.

Floor stand kit (required for NEMA Type 3R applications) – Kit includes two stands. Larger cabinets require two kits (4 stands). 6″H stands standard and 12″ stands are optional.

Rack assembly and installation – Exponential Power will assemble and mount the battery rack inside the cabinet so once the enclosure is set in place it can be loaded with the batteries. To permanently mount the rack, the floor stand kit is required.

DC cabling – Exponential Power will supply and connect the DC cables to the charger and provide the proper cable, lugs and insulating covers needed to connect to the supplied battery
