BATTERY VOLTAGE COLLECTION CIRCUIT AND AUTOMOBILE

WIPO Patent Application WO/2019/214341

A1

A battery voltage collection circuit and an automobile. The battery voltage collection circuit comprises a collection unit (30), a trigger unit (20) and a controller (10). The collection unit (30) comprises an input end for connecting to a storage battery (40), an output end connected to a voltage collection port of the controller (10), and a control end for controlling the conduction of the input end and the output end. The trigger unit (20) comprises an input end connected to a drive port of the controller (10), and an output end connected to the control end of the collection unit (30). When the drive port of the controller (10) outputs a drive signal, the trigger unit (20) triggers the conduction of the input end and the output end of the collection unit, such that the voltage collection port of the controller (10) collects a voltage of the storage battery (40). When the drive port of the controller (10) does not output a drive signal, the battery voltage collection circuit does not work, the input end and the output end of the collection unit (30) are non-conductive, the collection unit (30) does not consume the electric energy of the storage battery (40), and the circuit enters a low power consumption state, thereby avoiding causing the feeding of the storage battery (40) and avoiding impacting the user experience.
