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.
Claims20
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.
A computer-implemented method, comprising:
- operating, by a system coupled to a processor, respectively, modular battery cell devices in at least one defined operation mode;
- and
- providing, by the system, concurrently, an alternating current energy supply and a direct current energy supply from the modular battery cell devices.
A system, comprising:
- a vehicle having an electric driveline;
- and
- a battery pack that is coupled to the electric driveline and that uses an alternating current energy supply of the battery pack to provide a direct current energy supply when the vehicle is at a standstill.
