Problems solved by technology
The second traditional multi-cell battery management architecture can reduce the cost of the battery pack, because it uses the hardware and software on the EC 230 to complete the measurement of the remaining power of the multi-cell battery 215, but the disadvantage is that it cannot obtain a single battery cell voltage, which is detrimental for single cell management of multiple cells 215
The first type of traditional multi-cell battery management architecture measures the voltage of each battery cell and can manage each battery cell, but the disadvantage is that the cost of the battery pack will be higher, because the battery pack 10 is pre-installed when it leaves the factory. Complete but time-consuming calibration and measurement are required. In addition, the battery pack 10 needs to have a built-in microprocessor and related detection modules in it

Embodiment Construction
[0032] As previously mentioned, the first conventional multi-cell management architecture ( figure 1 ) and the second traditional multi-cell battery management architecture ( figure 2 ), each has its advantages and disadvantages. The present invention provides another multi-cell battery management framework which includes the above two advantages. Please refer to image 3 The block diagram shown. The battery pack 310 includes a plurality of battery cells 315, a battery protection circuit 320, a battery electrical and non-electrical detection module 325, and a slave battery communication protocol controller 340s. A portable electronic device 350 such as a notebook computer includes an EC (embedded control device) 330, a battery power calculation module (gauge, packaged in the EC embedded controller 330), and a main battery communication protocol controller 340m. Battery Communication Protocol The controller has other battery communication protocols besides SMBus, for examp...

The invention provides a multisection battery core management system, comprising a battery pack and a portable electronic device, wherein the battery pack comprises electric and non-electric detecting modules of a battery, multisection battery cores and a slave battery communication protocol controller; while the portable electronic device comprises an embedded controller and a master battery communication protocol controller; parameters needed for calculating the remaining electric quantity of the battery are measured in the battery pack, while the calculation of the remaining electric quantity of the battery is carried out by the embedded controller of the portable electronic device, therefore, the battery pack can achieve the purpose of managing each battery core without using a microprocessor.
Description
technical field [0001] The present invention relates to a battery remaining power management framework, in particular to a battery with multi cells remaining power management system. Background technique [0002] Batteries can be said to be the source of power for all portable electronic devices, such as mobile phones, notebook computers, personal digital assistants, walkmans, etc., all rely on batteries to provide power. But after all, the battery is just a device for storing electricity, and the electric energy of the battery is consumed when the portable electronic device is used. When the portable electronic device is turned on for use, the battery power will continue to be consumed until the portable electronic device is turned off or when the remaining power is not enough to drive the device, the portable electronic device will be forced to turn off. The latter means that the power stored in the battery is below a critical value. Generally speaking, regardless of env...
