Technical Level Technique threshold 1. Cost: LiFePO4 cost is too high ( Cost about 4-5 times Gel battery) 2. Temperature: Low temperature caused battery unable to use 3. Life: A number of series batteries caused battery cycle short life Solution: Hirate Energy Gel battery combine with Battery Management System ( DOD100%,battery life can maintain approximately 500 times-HRE series) HiRate Energy 20

Conclusion Classification Project Traditional Storage Energy System Hirate Energy Storage Energy System System Price Basically the same price System Life 2-3 years 4-6 years Management Maintenance Need to arrange staff on-site inspect at fixed period, if meet defective battery, have to change it any time Via computer processing remote system management and battery change is unnecessary Data Contents Commonly test voltage Record real-time voltage 、 current and temperature Abnormal notice No abnormal notice function If happen abnormal condition, it will give warning message Maintenance Cost Higher maintenance cost Basically maintenance cost is zero HiRate Energy 21

Due to the whole system becomes double life ， and its price did not increase. The entire management cost and personnel cost is greatly reduced as well. Consequently, whether system performance or use cost, Hirate Energy storage energy system is better than ordinary storage energy system HiRate Energy 22 Conclusion
