The battery is usually used as a backup power source for the power distribution system, and when the power distribution system fails, the battery will take over the power distribution system to temporarily supply power to the load. Therefore, once the battery has a problem, the power distribution system is likely to have major accidents such as electric power breakdown and equipment stop running.
When the battery is used as a standby power supply, the battery is usually in a floating charge state, but long-term floating charge causes problems of pole plate vulcanization, water loss and the like, and the performance of the battery is reduced. Therefore, the battery needs to be checked for capacity periodically.
However, when the prior art performs the capacity check on the battery, the current battery is usually required to be removed from the power distribution system, another battery set is replaced, and then the capacity check is performed on the removed battery, which consumes a lot of manpower and material resources.

It should be noted that, for a component not limited in the following description, the component is not necessary for the following operation mode, and the specific function of the component can be referred to the above embodiment.
1. Normal mode of operation
By way of example, the operation process of the nuclear capacity discharge device provided in the embodiment of the present application in the normal operation mode is described with reference to fig. 3.
In the normal operation mode, the control main unit 101 sets the ac contactor 105 to a closed state and sets the dc contactor 104 to an open state.
Ac power in the distribution system enters the rectifier 116 through the ac contactor 105, and the rectifier 116 converts the ac power into dc power and outputs the dc power to the load device 117 and the battery, respectively. Accordingly, the load device 117 receives the dc power output from the rectifier 116 to operate normally. The battery receives the dc power output from the rectifier 116 to float or level.
2. Standard kernel capacity mode of operation
Since the battery parameters detected by the battery under different conditions are different, the battery parameters detected by the battery under specific conditions are used as standard parameters.
Exemplary, discharge at a rate of 10 hours(i.e. I) 10 ) For the standard, the operation process of the nuclear capacity discharge device provided in the embodiment of the present application in the standard nuclear capacity operation mode is described with reference to fig. 4.
(1) Starting phase
The control host unit 101 determines whether it conforms to I according to the configuration information and the battery parameters 10 And (4) nuclear capacity discharge conditions. If the condition is satisfied, the battery capacity check device 10 will start the standard capacity check operation mode. The control host unit 101 sets the ac contactor 105 to the open state and sets the dc contactor 104 to the closed state.
(2) Execution phase
At this point, the battery will automatically output dc power as the ac contactor 105 is opened and the power distribution system is no longer providing ac power. The dc power output from the battery flows to the load device 117 to supply power to the load device 117; on the other hand, the current flows to the dc contactor 104, and flows to the smart discharging module 103 through the dc contactor 104. Therefore, the current output by the battery includes the current received by the load terminal 115 and the current received by the smart discharging module 103.
Due to I 10 The constant output I of the battery is ensured when the nuclear capacity discharge is required 10 Therefore, the control host unit 101 can determine the current output by the battery according to the first current detection circuit 106 and determine the current received by the load terminal 115 according to the second current detection circuit 107, so as to control the intelligent discharge module 103 to adjust the current received by the intelligent discharge module 103 in real time, so that the battery can output I 10 The current is measured.
(3) End phase
When the end condition is satisfied, the battery capacity verification apparatus 10 performs an end operation. Illustratively, the configuration information includes a cutoff voltage. The control host unit 101 acquires the voltage of the battery in real time according to the battery monitoring module 102. When the voltage of the battery is less than or equal to the cutoff voltage, the control host unit 101 controls the battery capacity device 10 to switch to the normal operation mode. At the same time, the control host unit 101 generates a standard core capacity detection report. The standard capacity check report includes the current standard capacity of the battery.
3. Load kernel capacity mode of operation
The load capacity refers to the battery capacity device 10 detecting the battery parameter when the battery is supplying power to the load device 117. Through the load capacity detection, the battery capacity detection device 10 can determine the power supply time and the power supply capacity of the battery under the actual condition.
For example, the working process of the core capacity discharge device in the load core capacity working mode according to the embodiment of the present application is described with reference to fig. 5.
(1) Starting phase
The control host unit 101 determines whether the condition of the load capacity discharge is met according to the configuration information and the battery parameters. If the condition is satisfied, the battery capacity check device 10 will start the load capacity check operation mode. The control main unit 101 sets the ac contactor 105 to an open state and sets the dc contactor 104 to a closed state.
(2) Execution phase
At this point, the battery will automatically output dc power as the ac contactor 105 is opened and the power distribution system is no longer providing ac power. The control host unit 101 controls the intelligent discharge module 103 such that the current received by the intelligent discharge module 103 is set to 0, i.e., does not receive the direct current supplied from the battery. Thus, the current output by the battery will only be used to provide current to the load device 117.
(3) End phase
When the end condition is satisfied, the battery capacity verification apparatus 10 performs an end operation. Illustratively, the configuration information includes a cutoff voltage. The control host unit 101 acquires the voltage of the battery in real time according to the battery monitoring module 102. When the voltage of the battery is less than or equal to the cutoff voltage, the control host unit 101 controls the battery capacity device 10 to switch to the normal operation mode. At the same time, the control host unit 101 generates a load kernel capacity detection report. The load nuclear capacity detection report comprises the power supply time and the power supply capacity of the battery under the actual condition.
