The Hours Shift
Understanding peak and valley hours needs no formula. The system adjusts to conditions, and one good setup beats patching the schedule again and again whenever the prices happen to move.
Lower The Long Term Cost
Moving routine charging into valley hours is the simplest win. A fixed off-peak slot keeps the yearly bill lower without changing how people drive or when they actually need the car.
Practical Notes
Set a timer or a reservation for the cheap window, and review the bill monthly. Small, steady shifts beat one dramatic change that nobody on the team can actually sustain for long.
Across Yantai districts, Dongshang New Energy points users to the valley window so the saving is easy to catch and the habit forms without a dull lecture about the tariff structure. The users who benefit most are the ones with a fixed routine, because the cheap window does the saving for them automatically, and they never have to think about the tariff again except to enjoy the lower total.
