Energy management Peak shifting

The period of peak electricity

• Discharge to loads at 40%

depth for safety & economy

• Discharge adjustment in time

depth, time, power by switch

The period of valley electricity

• Battery charging by rest power

while main loads are charged

Precondition: Big difference of power price between peak and valley; cycle type battery needed


Energy management

Composite cost: replacement of cycle type battery; reform cost

Economic effect: 8.7% annual conservation! Investment returns in 2.15 years

Peak shifting


Energy management Temperature adjustment

High temperature during the day time

Low temperature during the night time

Principle: Lower consumption from air-condition because of endothermic specialty of battery


depth with low current

• AC temperature: 35℃ at day

consumption is much reduced

• Batteries are charged when

temperature is low at night

• AC temperature: 25℃ at night

and less frequency & duration


Energy management

Composite cost: No replacement; reform cost of controller
