Hangzhou Zhongheng Electric Co., Ltd

GMDE used power battery cascade energy
storage solution

The Solution provides the energy storage and micro grid clients with station energy dispatching, power station safety management, automatic operation & maintenance and intelligent operation, as well as provides the operation optimization, intelligent control and other management services for the whole lifecycle of the electric power market.

Solution Advantages Value creation

Available to directly use without disassemble required, which reduces the system cost

Retain the original BMS and mechanism design, the cost of the whole cascade energy storage system is as low as CNY 1 /Wh, and the investment return period is shortened by 40-60%

Group serial distributed architecture solves the battery consistency

GMDE group serial energy storage inverter is used and the group serial distributed architecture is to creatively adopted to maximize the consistency of licensed batteries

Low rate charging and discharging strategy (＜0.2C) ensures long service life of the system

By controlling the discharge rate and discharge degree, the safety and reliability of the cascade energy storage system are increased.

GMDE used power battery cascade energy storage solutions

The system deploys the operation strategy as peak cut. The low-voltage side grid charges the energy storage system during the off-peak electricity rate stage, and the energy storage system supplies power to the load during the peak electricity rate stage, so as to share the benefits brought by the peak and off-peak rate difference with customers through the business mode as contract energy management.

Peak cut strategy brings profit

By means of charge at off-peak and discharge at peak strategy, the profit from price difference of electricity at peak and off-peak can be obtained.

On-demand electricity fee management

By continuously recording and analyzing users' power consumption behaviors, reasonable charging and discharging strategy can be generated in combination with local electricity rate policy to reduce users' peak power consumption, so as to achieve the purpose of reducing electricity fee.

Smooth electricity load

The energy storage system discharges at the peak hour and reduces the rate of load change to achieve the purpose of smoothing load.

Reduce energy storage costs

The cascade utilization of power batteries improves the overall economy of the energy storage system and maximizes the cycle life of used power lithium batteries
