Battery control circuit and battery control system

The utility model provides a battery control circuit and a battery control system. The battery control circuit comprises a main control assembly and a first controllable switch assembly, the first controllable switch assembly comprises a main path and a parasitic path, the main path is an on-off controllable path, and the parasitic path is a one-way normally open path; the control end of the first controllable switch assembly is connected with the main control assembly, the first end of the first controllable switch assembly is connected with the positive electrode of the battery, and the second end of the first controllable switch assembly is connected with the load. When the first controllable switch assembly is turned on, current output by the positive electrode of the battery flows into the load through the main path; when the first controllable switch assembly is turned off, the current output by the positive electrode of the battery flows into the load through the parasitic path.
