Abstract
An online detection apparatus for a storage battery is provided. The battery, serving as standby power, is connected in parallel with a power supply in an electric device circuit. The apparatus includes a control unit, a discharge circuit, and a battery monitoring unit. After detecting a trigger event, the control unit instructs the discharge circuit to boost the battery voltage to match or exceed the power supply, initiating discharge. During this state, the battery monitoring unit evaluates the battery's discharge performance. Both the discharge circuit and monitoring unit are electrically coupled to the control unit.
Claims9
An online detection apparatus for a storage battery, the storage battery being connected in parallel with a power supply in a working circuit of an electric device and being a standby power supply of the power supply, wherein the apparatus comprises:
- a control unit comprising circuitry configured to send boost enable instruction when detecting a detection trigger event of the storage battery;
- a discharge circuit connected in series with the storage battery and electrically coupled to the control unit, wherein the discharge circuit is configured to receive the boost enable instruction from the control unit and to control a voltage of the storage battery to be increased to greater than or equal to a voltage of the power supply according to the boost enable instruction to enable the storage battery to enter a discharge state, wherein the discharge unit further comprises:
- a positive output terminal connected to a series connection path between a positive electrode of the power supply and the electric device,
- a positive input terminal and a negative output terminal connected to a positive electrode of the storage battery,
- a negative input terminal connected to a series connection path between a negative electrode of the storage battery and the electric device, and
- a first controlled switch component provided between the positive output terminal and the positive input terminal and the negative output terminal, the first controlled switch component being configured to connect the positive output terminal of the discharge circuit to the positive input terminal and the negative output terminal of the discharge circuit according to the boost enable instruction;
- and
- a battery monitoring unit comprising circuitry electrically coupled to the control unit and configured to detect discharge performance of the storage battery when the storage battery enters the discharge state.
