Manufacturing scale and organization

The team behind JKESS began working in the new energy and energy storage sector in 2017. JKBMS Electronic Technology Co.,Ltd was formally established in 2023, followed by the launch of the JKESS energy storage brand in 2024.

Today, the company operates a 70,000-square-meter manufacturing facility on a 120-mu site, supported by more than 700 full-time employees, including over 100 R&D professionals. Current annual production capacity reaches 2.1 GWh.

JKESS products and solutions are supplied to customers across more than 200 countries and regions. The company provides BMS control hardware, battery enclosure kits, high-voltage battery management systems, and configured commercial and industrial energy storage cabinet solutions.

Product-level certification, test scope, factory acceptance testing, third-party inspection, and project documentation vary by model and order. Buyers should rely on the documents specifically identified in the signed quotation rather than assuming every certificate or service applies to every product.

Quality workflow

Checks should follow the actual product and supply scope

Configuration review

The product model, selected option, voltage, current, communication, included hardware, destination, quantity, and project-specific requirements should be confirmed against the quotation or order record before production or packing.

Incoming material and component checks

Mechanical parts, control hardware, displays, harnesses, connectors, and other supplied components are checked against the applicable bill of materials and purchasing requirements before assembly.

Assembly and workmanship checks

Applicable checks include enclosure condition, fasteners, labels, cable routing, connector seating, insulation, grounding points, and the hardware included for the selected package.

Functional verification

Testing depends on the supplied product. It can include power-up checks, display and communication checks, voltage or current measurement verification, input and output inspection, and confirmation of configured control hardware.

Packing and shipment verification

The final packing list, product quantity, accessories, protection materials, labels, gross weight, dimensions, and freight requirements are checked before dispatch documentation is issued.

Documents to confirm before shipment

The controlling document is the signed quotation or order confirmation. It should identify what the buyer receives, what remains outside the scope, and which technical or compliance documents will be supplied.

Signed quotation or order confirmation defining the exact supply scope
Model and option list, quantities, and applicable packing list
Product datasheet, user manual, or wiring information where available
Communication protocol or compatibility statement when included in the project scope
Inspection, test, or configuration records when agreed for the order
Warranty, shipping, return, safety, and installation responsibility documents
Certificates or compliance documents only when applicable to the selected product and confirmed in writing

Request order-specific evidence

Send the product, option, quantity, destination, certification target, inspection requirement, and required documents so they can be confirmed in the quotation.
