A robot power management system and robot

Abstract

The invention provides a robot power management system. The system comprises a power supply, a DCDC circuit, a power circuit, a power control circuit and a processing chip, wherein a negative electrode of the power supply and the power circuit are respectively grounded; a positive electrode of the power supply is connected with the power control circuit, the DCDC circuit and the processing chip in series; an ungrounded end of the power circuit is connected with the power control circuit; and the power control circuit is further provided with a voltage output interface used for outputting voltage to a DC motor. Therefore, the robot power management system provided by the invention uses the power control circuit to convert the voltage of multiple batteries connected in series into a control signal, the processing chip controls the system power supply according to the signal, and the existing processing chip realizes the power management of the multiple batteries connected in series. The invention further discloses a rotor, which includes any of the above robot power management systems, and has the same technical effect.

Description

technical field [0001] The invention relates to the technical field of embedded hardware power management, in particular to a robot power management system and a robot. Background technique [0002] At present, the development of intelligent hardware products is very rapid, and there are many product categories such as mobile phones, tablets, VR, intelligent robots, smart speakers, etc. Some of these products use multiple batteries in series due to system requirements (such as motors, high-power speakers, etc.). It is connected in series to ensure sufficient working voltage and power. At present, the hardware platforms of most products are processing chips based on ARM architecture, and these processing chips are based on the voltage range of a single battery, usually with a withstand voltage of only 0 to 5.5 V is about V, and in the prior art, the voltage requirement of many products is 9V or 12V. If the multi-cell battery series solution is adopted, it will exceed the mana...

Problems solved by technology

[0002] At present, the development of intelligent hardware products is very rapid, and there are many product categories such as mobile phones, tablets, VR, intelligent robots, smart speakers, etc. Some of these products will use multiple batteries in series due to system requirements (such as motors, high-power speakers, etc.) The form of series connection is to ensure sufficient working voltage and power. At present, the hardware platform of most products is based on the processing chip of ARM architecture, and these processing chips are based on the voltage range of a single battery, and the withstand voltage is usually only 0~5.5 V is about V, and in the existing technology, the voltage requirement of many products is 9V or 12V. If the scheme of connecting multiple batteries in series is adopted, it will exceed the management range of the processing chip for the power supply voltage in the prior art, and there is a risk of the processing chip being overloaded and burned.
