| 发明名称 | Battery management system and method of dynamically allocating charging current | ||
| 摘要 | A battery management system includes a power converter, a first switch, a second switch, a first detecting unit, and a CPU. The power converter is configured to divide current provided by the power supply into a first and a second output current, according to a working current of a system load in a normal state, the first output current is used to power the system load, and the second output current is used to charge a battery unit. The CPU is configured to determine whether the value of current detected by the first detecting unit is greater than a threshold value, and further controls turning on the first switch to power the system load using the first output current, and turn on the second switch to charge the battery unit using the second output current. | ||

| 主权项 | 1. A battery management system, comprising: a system load; a battery unit; a power converter for being connected to a power supply, configured to divide current provided by the power supply into two output currents, according to a working current of the system load in a normal state, wherein a first output current is to power the system load, and a second output current is to charge the battery unit, the amount of the first output current being changed according to the demand of the system load, and the amount of the second output current being changed according to the changing of the first output current inversely; a first switch; a second switch; a first detecting unit connected to the input of the power converter, configured to detect the current which is provided by the power supply; and a CPU, configured to determine whether the value of the current detected by the first detecting unit is greater than a threshold value, and further controls to turn on the first switch to power the system load by the first output current, and to turn on the second switch to charge the battery unit by the second output current if the value of the detected current is greater than the threshold value. | ||
