Engineering that
starts at the cell level.
From the battery management system (BMS), which keeps the battery running safely and efficiently, to thermal management and modular system integration — these are the technology layers that set REAP apart.
One BESS container,
five layers of engineering.
A BESS (battery energy storage system) container is a complete, ready-to-install unit that holds the batteries and everything that keeps them safe — cooling, fire safety, monitoring and the connections that link it to the power grid. Here is how it is built, layer by layer.
Maintenance-free side access.
Double-wing service doors with stainless steel hinge system and gasket + buffer structure, plus maintenance-free sides and inlet louver for weather and dust resistance.
BMS access + EMS connections.
Electrical compartment with access to the battery management system (BMS), plus connections to the energy management system (EMS) — the software that decides when and how stored energy is used. CAN, RS485 and TCP/IP communication for monitoring and automation. Operation box and alarm box for field engineers.
Active liquid cooling system.
An air-to-liquid chiller with a liquid cooling pipeline keeps every cell at an even temperature. Compressor, radiator and circulation pump work together as a thermal management system (TMS) — the part that keeps the batteries cool so they last longer and stay safe.
Multi-layer detection + suppression.
A fire suppression system (FSS) detects trouble early and puts out a fire before it can spread. Gas sensor, smoke detector and temperature sensor trigger aerosol suppression, a water sprinkler pipeline and a pressure-relief (deflagration) panel. UL 9540A, IEC 62619 compliant.
Parallel connection from the top.
Roof module internal connector panel — DC busbar, communication and sensor lines. Parallel expansion up to 5 MWh per container in stack mode, with crane lifting points for installation.
Battery Management System
The BMS keeps the battery running safely and efficiently. It watches each cell, tracks how full and how healthy the battery is (state of charge and state of health), and balances the cells for safe, reliable operation.
Safety Architecture
5-layer safety from cell to field level. UL 9540A, UL 1973, IEC 62619 compliant architecture.
Energy Management System
The EMS decides when and how stored energy is used. It monitors the system in real time, warns of problems early using a big-data warning system, and corrects itself automatically (closed-loop correction).
Scalable Architecture
One architecture from 5 kWh residential to 5 MWh utility-scale — modular scalable design.
Liquid Cooling System
Homogeneous thermal distribution with active liquid cooling for consistent performance and longer service life.
From cell
to container.
The system is built up step by step: a cell becomes a module, modules become a pack, packs become a rack, and racks fill a container. A single modular architecture scales from 5 kWh for a home to 5 MWh for the grid — the same LFP (lithium iron phosphate) cell, the same liquid cooling platform, the same IP55 protection.
Cell
Lithium iron phosphate (LFP) cells with cell-level monitoring and 6,000+ cycle life.
Module
One module platform serves energy storage systems (BESS), forklifts, AGVs (automated guided vehicles) and other mobility uses — its cells can be rewired in series or parallel to suit each job.
Pack
LiqPack-314Ah series in 1P52S or 1P104S configurations, IP67 liquid-cooled, ~350 kg per unit.
Rack
LiqRack-314Ah 1P416S — 418 kWh at 1331 V nominal. 4 packs + 1 HV box per rack, Class B functional safety.
Container
20-foot high-cube containerized BESS with integrated fire suppression, thermal management, BMS, deflagration panel and forced exhaust.
