Abstract

Devices, systems, methods, computer-implemented methods, and/or computer program products to facilitate an intelligent battery cell with integrated monitoring and switches are provided. According to an embodiment, a device can comprise active battery cell material. The device can further comprise an internal circuit coupled to the active battery cell material and comprising: one or more switches coupled to battery cell poles of the device; and a processor that operates the one or more switches to provide a defined value of electric potential at the battery cell poles.

Claims (13)

1. A system, comprising:

modular battery cell devices coupled to one another and comprising internal circuits that are used to respectively operate the modular battery cell devices in at least one defined operation mode to concurrently provide an alternating current energy supply and a direct current energy supply; and

switches that couple the modular battery cell devices to an alternating current terminal and a direct current terminal.

2. The system of claim 1 , further comprising:

a control unit that operates the switches to couple the modular battery cell devices to the alternating current terminal and the direct current terminal to concurrently provide the alternating current energy supply and the direct current energy supply, respectively.

3. The system of claim 1 , further comprising:

a control unit that operates the switches to couple the modular battery cell devices to the alternating current terminal and the direct current terminal to concurrently provide the alternating current energy supply at the alternating current terminal and receive a charging direct current energy supply at the direct current terminal.

4. The system of claim 1 , further comprising:

a control unit that operates the switches to couple the modular battery cell devices to the alternating current terminal and the direct current terminal to concurrently receive a charging alternating current energy supply at the alternating current terminal and provide the direct current energy supply at the direct current terminal.

5. The system of claim 1 , further comprising:

a control unit that respectively provides operation instructions to the internal circuits to respectively operate the modular battery cell devices in the at least one defined operation mode to concurrently provide the alternating current energy supply and the direct current energy supply.

6. The system of claim 1 , wherein the modular battery cell devices respectively operate in a defined operation mode to respectively provide a defined value of electric potential at battery cell poles of the modular battery cell devices, and wherein at least one of the defined operation mode or the at least one defined operation mode comprises an off mode indicative of a zero value of electric potential, a bypass mode indicative of the zero value of electric potential, a positive mode indicative of a positive value of electric potential, and a negative mode indicative of a negative value of electric potential.

7. The system of claim 1 , wherein the internal circuits comprise transformers that respectively provide a defined direct current energy supply at battery cell poles of the modular battery cell devices and electrically insulate the alternating current energy supply from the direct current energy supply.
