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, high efficiency.
The EnerOne+Energy Storage productis capable of variouson-grid applications, such as frequency regulation,voltage regulation, arbitrage,peak shaving and valley filling, and demand response. Furthermore, the EnerOne+Rackcan be used for PV storage integration and Wind storage integration. The system can also operate as amicrogrid to support backup and islanded systems.

Overview

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

Battery

The capacity of cellis 306Ah,1P52S cells integrated in one module,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,andensure the stable operation of the energy storage system.It canmanageenergy absorption and release, the thermal management system andauxiliarypower supplyaccording to the detectedinformation:battery voltage, currentandtemperature.It canmonitorhigh voltage DC/AC security, diagnosis and analysis faultsaccording informationfrom various detectors and dry-contacts.Andit cankeep communicationwith PCS and EMSthrough CAN.

FSS

FSS consists of smoke detectorand heatdetector(Orheatdetector and gasdetector), the aerosol, the dry pipe(optional).FSSundertakesfunctions :monitorthe thermalrun-awayrisks ofRackthroughthedetectors, extinguishthe thermal run awayin an early stage, andcontrol the loss to minimum. The FSS is independent with any other systemandit is the security guard of EnerOne+Rack.

TMS

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

Controlbox

Control box mainly includes detection device, protection device andAC/DC power supply. The structure is shown as follows.
