AI Technical Summary

Problems solved by technology

The cost of the battery management system is higher due to the higher price of high voltage diodes
And, the response speed of the high-voltage diodes is relatively slow, before the high-voltage diodes 331 and 332 respond and take protective measures, the battery management chips 301 and 302 may have been damaged
In addition, to ensure forward conduction, several milliamperes are required, which increases the power consumption of the battery management system

Abstract

A battery management chip may include a battery management unit and a vertical bus circuit. The battery management unit can monitor a cell status of multiple cells in a battery module coupled to the battery management chip in response to an instruction from a host processor. The vertical bus circuit may transfer the instruction from the host processor to the battery management unit. The vertical bus circuit may include a first receiver, a command processor and a first transmitter. The first receiver can receive a first pair of differential input data signals. The command processor can process the first pair of differential input data signals. The first transmitter can output a first pair of differential output data signals.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a battery management chip, a battery management system and a method. Background technique [0002] Multiple battery modules can be used to power various electronic devices. To monitor the status of the plurality of battery modules, a plurality of battery management chips are connected to the battery modules, and a host processor is connected to the plurality of battery management chips. [0003] figure 1 Shown is a block diagram of a conventional battery management system 100 , wherein a host processor 120 is connected to a battery management chip through a common bus 130 . Such as figure 1 As shown, the battery management system 100 includes a plurality of battery modules (such as the battery module 140-1, the battery module 140-2, and the battery module 140-3). 101. A battery management chip 102 and a battery management chip 103 are coupled, wherein each battery ...
