The invention provides a high-voltage power-on method for a battery system, a storage medium and a processor, and the method comprises the steps: transmitting a first instruction to a battery management system when determining that the battery temperature of the battery management system meets a preset condition, the first instruction being used for closing a high-voltage contactor of the battery management system; the battery management system responds to the first instruction; sending a second instruction to the thermal management system, wherein the second instruction is used for closing a pre-charging contactor of the thermal management system; the thermal management system responds to the second instruction; when it is determined that the working condition information meets the preset condition, a third instruction is sent to the thermal management system, and the third instruction is used for closing a high-voltage contactor of the thermal management system; the thermal management system responds to the third instruction; sending a fourth instruction to the thermal management system, wherein the fourth instruction is used for disconnecting a pre-charging contactor of the thermal management system; and the thermal management system responds to the fourth instruction. The problem that the service life of a high-voltage contactor of the thermal management system is shortened due to a high-voltage method on an existing battery system is effectively solved.
