Abstract
Various examples of the present disclosure provide a high efficient battery system, and systems and methods for intelligently discharging and charging the battery system such that an output voltage of the battery system is maintained within a predetermined voltage range. In some examples, a base board controller (BMC) is used to manage charging and discharging of the battery system. The BMC can provide both over-charging protection and over-discharging protection for the battery system.
Claims16
A computer-implemented method for charging and discharging a high efficient battery system of a server system, comprising:
- receiving, at a base board controller (BMC) of the server system, status information of an AC power supply and a power supply unit (PSU) of the server system;
- in an event that either the AC power supply or the PSU fails, generating a discharging-enable command to enable the high efficient battery system to discharge power to the server system;
- receiving status information of the high efficient battery system via a communication interface;
- and
- in an event that an output voltage of the high efficient battery system is equal or below a threshold low value, generating a discharging-disable command to disable the high efficient battery system from further discharging power to the server system;
- wherein the high efficient battery system comprises a microcontroller unit (MCU), a battery charger, a battery pack, and an Oring MOSFET, and wherein the high efficient battery system does not include a discharging DC/DC converter;
- wherein the battery charger is connected to an output of the PSU;
- and wherein the MCU is coupled to the BMC via the communication interface.
A system for charging and discharging a high efficient battery system, comprising:
- a processor;
- and
- a non-transitory computer-readable medium storing instructions that, when executed by the processor, cause the system to perform operations comprising:
- receiving, at a base board controller (BMC) of the system, status information of an AC power supply and a power supply unit (PSU) of the system;
- in an event that either the AC power supply or the PSU fails, generating a discharging-enable command to enable the high efficient battery system to discharge power to the system;
- receiving status information of the high efficient battery system via a communication interface;
- and
- in an event that an output voltage of the high efficient battery system is equal or below a threshold low value, generating a discharging-disable command to disable the high efficient battery system from further discharging power to the system;
- wherein the high efficient battery system comprises a microcontroller unit (MCU), a battery charger, a battery pack, and an Oring MOSFET, wherein the high efficient battery system does not include a discharging DC/DC converter;
- and wherein the battery charger is connected to an output of the PSU, and wherein the MCU is coupled to the BMC via the communication interface.
A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a system, cause the system to perform operations enabling charging and discharging a high efficient battery system, comprising:
- receiving, at a base board controller (BMC) of the system, status information of an AC power supply and a power supply unit (PSU) of the system;
- in an event that either the AC power supply or the PSU fails, generating a discharging-enable command to enable the high efficient battery system to discharge power to the system;
- receiving status information of the high efficient battery system via a communication interface;
- and
- in an event that an output voltage of the high efficient battery system is equal or below a threshold low value, generating a discharging-disable command to disable the high efficient battery system from further discharging power to the system;
- wherein the high efficient battery system comprises a microcontroller unit (MCU), a battery charger, a battery pack, and an Oring MOSFET, wherein the high efficient battery system does not include a discharging DC/DC converter;
- and wherein the battery charger is connected to an output of the PSU, and wherein the MCU is coupled to the BMC via the communication interface.
