Problems solved by technology

However, the content of ROM cannot be updated, and RAM is not suitable for storing data, because once the power of the battery management system chip is cut off, its content will disappear completely
Therefore, a simple microcontroller-type battery management system chip cannot be used to load the learning program to correctly reflect the battery parameters to achieve the learning effect

Embodiment Construction

[0033] The invention provides a battery management system integrating a flash chip into a battery management microcontroller chip. The flash chip has the characteristics of rewriting (programming), erasing (erase) and saving data without consuming power, so it is suitable for storing application programs and related parameters of battery management. According to the present invention, the flash chip is stacked outside the battery management microcontroller chip. The purpose of integration can be achieved by using an interface module (I / F module) as a bridge between the traditional battery management microcontroller chip and the flash chip. The system of the present invention can be applied to commercially available flash chips and microcontroller chips, thereby greatly reducing the development time of the battery management system chip.

[0034] As shown in FIG. 1 , it is a schematic circuit block diagram of the battery management system chip of the present invention. In add...

Abstract

The invention is a battery management system, including: Flash Microcontroller chip deposited of battery management learning procedures, and battery management.Among them, besides with traditional and suitable Microcontroller, battery management Microcontroller also contains a flash interface module as a interface between a flash chips and the central processing unit (CPU). In addition to address register, data register as a interface of the address and data transmission between the flash 8 CPU chips and 16 CPU chips, flash interface module but also contains logical control circuitry needed by literacy control of flash chip, the circuitry required for read-in control interface as by external mainframe into flash chip. This invention enables system designers to come into the market after the hardware of chip management and basic software development process is completed, is helpful to reduce the time which the chip goes on the market. Moreover, because of the design of the invention, making the stack on chip, flash chips can be applied to the eight commercial flash chips and increased use of convenience.

Description

technical field [0001] The invention relates to a battery management system, in particular to a battery management system chip with a stacked memory. Background technique [0002] The power supply of the portable device mainly comes from the battery, and the battery is limited by the volume of the portable device, so that its stored power is quite limited. Therefore, the power consumption rate of the portable device has changed from the past It has been one of the focuses of designers until now. Therefore, at present, in advanced portable devices, a "battery management" chip system is used to improve battery performance. The battery management system chip controls and manages important parameter data and related testing procedures such as the capacity, operating temperature, charge and discharge status, and accumulated charge and discharge times of the battery (such as lithium battery). The intelligent battery management system chip also includes the ability to update rele...
