How the saving works
Shandong's Energy Doc 2024-667 of August 19 2024 requires new residential fixed parking spaces to be 100 percent pre-equipped or reserved and pushes removal of property proof, so more residents get compliant independent-metering meters. Valley rates are clearly lower than flat rates, making night charging a felt saving. The NDRC pricing policy lets directly metered households voluntarily choose peak-valley rates, guiding orderly charging.
Qingdao experience
For Qingdao, the policy means home-pile users see each unit's price in the app. Operators make billing transparent so residents trust what they pay. Once grids enable peak-valley, plug in at night and wake to a full battery becomes routine.
Trust is the dividend
The deeper value is steering disorderly charging into orderly flow through price leverage, benefiting grid and user alike. Transparent billing is the bedrock of trust and repeat use. Operators should provide clear electricity-cost views; residents apply for independent metering and shift charging to valley hours.
