3. Resistance up to C5 corrosion level, with 20-year reliability

4. Separate fire protection system

Long service life

1. Available for integration with CATL's advanced technologies (e.g. optional cell with super-long cycling up to 12,000 cycles)

2. Integrated frequency conversion liquid-cooling system, with cell temperature difference limited to 3℃, and a 33% increase of life expectancy

High integration

1. Modular design, compatible with 600 - 1,500V system

2. Separate water cooling system for worry-free cooling

3. Modular design with a high energy density, saving the floor space by 50%

4. Transportation after assembly, reducing on-site installation costs and commissioning time


Application

The EnerOne+Rack is a modular fully integrated product, consisting of rechargeable lithium-ion batteries, with the characteristics of high energy density, long service life, and high efficiency.

The EnerOne+Energy Storage products are capable of various grid applications, such as frequency regulation, voltage regulation, arbitrage, peak shaving and valley filling, and demand response. Furthermore, the EnerOne+Rack can be used for PV storage integration and Wind storage integration. The system can also operate as a microgrid to support backup and islanded systems. 

The EnerOne+Rack consists of the following parts: batteries, BMS, FSS, and TMS, which are integrated together to keep the normal working of Rack.


Overview


0.5P EnerOne+ Outdoor Liquid Cooling Rack


Battery

The capacity of cells 306Ah,1P52S cells integrated into one module, and 8 modules integrated into one Rack. As the core of the energy storage system, the battery releases and stores energy.

BMS

BMSadopts the distributed scheme, through the three-level (CSC--SBMU--MBMU)architecture to control the BESS, and ensure the stable operation of the energy storage system. It can manage energy absorption and release, the thermal management system, and auxiliary power supply according to the detected information: battery voltage, current, and temperature. It can monitor high voltage DC/AC security, and diagnose, and analyze faults according to information from various detectors and dry-contacts. And it can keep communication with PCS and EMS through CAN.

FSS

FSS consists of a smoke detector and heat detector (Orheatdetector and gas detector), aerosol, and a dry pipe(optional).Functions: monitor thermal run-away risks of rack-through detectors, extinguish the thermal run-away in an early stage, and control the loss to a minimum. The FSS is independent of any other system and is the security guard of EnerOne+Rack.

TMS

TMS consists of one powerful chiller, one PTC heater, and the liquid cooling pipe distributed in each battery module. The TMS will keep the battery working at its best state and reach the longest life.

Control box

The control box mainly includes a detection device, protection device, and AC/DC power supply. The structure is shown as follows.
