A control method for an energy-storage apparatus, an energy-storage apparatus, and a storage medium are provided. The energy-storage apparatus supplies power to electrical devices, establishes a communication connection with a terminal bound to a target user, and includes a high-voltage box including a controller, and multiple energy-storage modules. The method includes: obtaining, by the controller, a current power of the energy-storage apparatus; determining, by the controller, power consumption of the energy-storage apparatus when the energy-storage apparatus normally supplies multiple the electrical devices in a future preset period; generating, by the controller, prompt information or an adjustment scheme of a running strategy for the energy-storage apparatus according to the current power of the energy-storage apparatus, the power consumption, and weather information of a location of the energy-storage apparatus in the future preset period; and controlling, by the controller, the energy-storage apparatus according to the adjustment scheme.
