Dual-output battery system

Abstract

A dual-output battery system includes a first battery module, a second battery module, a first output module, a second output module, and a switching control module. The first output module is coupled to the first battery module and an external device. The second output module is coupled to the second battery module and the external device. The switching control module is coupled to the first battery module, the second battery module, the first output module, and the second output module. The switching control module is configured to control the first output module to turn on or off based on either a first state of the first battery module or a load requirement of the external device, and to control the second output module to turn on or off based on either a second state of the second battery module or the load requirement of the external device.

Claims

1. A dual-output battery system, comprising: A first battery module and a second battery module; A first output module is coupled to the first battery module and an external device; A second output module coupled to the second battery module and the external device; and a switching control module coupled to the first battery module, the second battery module, the first output module and the second output module; wherein the switching control module is configured to control the first output module to turn on or off based on either a first state of the first battery module or a load requirement of the external device, and to control the second output module to turn on or off based on either a second state of the second battery module or the load requirement of the external device.

2. The dual-output battery system as described in claim 1, wherein, Either the first output module or the second output module is turned on, and the other of the first output module or the second output module is turned off.

3. The dual-output battery system as described in claim 1, wherein, The switching control module includes a detection unit and a control unit coupled to the detection unit. The detection unit is configured to detect the first state and the second state, and the control unit is configured to control the first output module and the second output module to turn on or off.

4. The dual-output battery system as claimed in claim 1, wherein, The first state includes the voltage, current, temperature, or a combination thereof of the first battery module.

5. The dual-output battery system as claimed in claim 1, wherein, The second state includes the voltage, current, temperature, or a combination thereof of the second battery module.

6. The dual-output battery system as claimed in claim 1, wherein, The first battery module is a niobium-based lithium-ion battery, and the second battery module is a ternary lithium battery.

7. The dual-output battery system as claimed in claim 1, wherein, The first battery module is a high-rate lithium-ion battery, and the second battery module is a high-energy-density lithium-ion battery.

8. The dual-output battery system as claimed in claim 1, wherein, The switching control module is coupled to the external device.

9. The dual-output battery system as claimed in claim 1, wherein, When the load demand of the external device exceeds a preset threshold, the switching control module controls the first output module to turn on.

10. The dual-output battery system as claimed in claim 1, wherein, When the load demand of the external device is lower than a preset threshold, the switching control module controls the second output module to turn on.
