The Joint Institute of Mechanical Engineering offers customers modular energy storage systems, including documentation development and upgrades at the customer's request, under a manufacturing agreement and/or a licensing agreement for their production and is looking for partners interested in a distribution services agreement.

Global and regional leaders in modular energy storage systems (BESS/ESS) include CATL, BYD, Tesla, Huawei Digital Power, and Sungrow. Their modular architecture allows for flexible capacity scaling from small commercial units to large megawatt-class industrial and grid-connected storage systems. Below is a structured list of leading global and local manufacturers of modular energy storage systems and their official websites.

Global Technology Leaders
1. CATL (Contemporary Amperex Technology Co., Limited): The world's largest manufacturer of lithium-ion cells and complete containerized and modular systems (EnerC, TENER series).
2. BYD (BYD Energy): A global giant offering both modular solutions for homes and businesses, as well as large-scale containerized systems based on safe Blade Battery batteries.
3. Tesla Energy: Known for its modular, scalable Powerpack (for commercial enterprises) and Megapack (for distribution grids) architectures.
4. Huawei Digital Power: A leader in the integration of digital technologies and power electronics. It produces modular Smart String ESS systems for the commercial and industrial sectors.
5. Sungrow Power Supply: One of the world's largest integrators of energy storage systems and general-purpose inverter equipment.
6. Fluence: A joint venture between Siemens and AES, specializing in modular hardware and software systems for grid stabilization.

The modular energy storage system, developed at the Joint Institute of Mechanical Engineering and based on lithium-containing cells, is a set of functionally complete, similar, and mutually coordinated components that enable the creation of energy storage devices with the capacity and voltage range required for vehicle powertrains or stationary energy storage systems.

The modules are a complete product designed for installation on commercial vehicles or stationary storage systems. The modules are equipped with a BMS system with passive or active balancing, a thermal stabilization system, and a disconnect switch for maintenance.

The modular energy storage system is adapted for use in the Eurasian Economic Community (EAEU) in terms of climatic conditions. Software solutions enable in-depth diagnostics of the system's technical condition and prevent premature failure of the storage devices.

Readiness for production:
availability of a prototype, design documentation with the letter "O", bench test results, and a certificate of conformity.

The Joint Institute of Mechanical Engineering completed the R&D project "Developing modular energy storage systems based on lithium-containing cells for electric vehicles and stationary installations". The results were used to create a modular electrical energy storage system.
