Description
Technical field
The relevant a kind of cell apparatus of the present invention, particularly a kind of cell apparatus that measures battery information.
Background technology
At present, must use the information that discharges and recharges or the temperature information that could measure battery corresponding to the fixture of the electrical quantity sensor of inside battery during the battery of the battery manufacturers of general notebook or associated electrical product before detection is dispatched from the factory.Usually cell apparatus there is no the information display interface, so use fixture corresponding to transducer to read and to show that measurement information becomes the necessary means that detects cell apparatus.For example, if use the electric quantity metering integrated circuit sensor BQ2050H of the Texas Instruments of Texas Instruments, then must use the corresponding fixture that Texas Instruments produced just can detect operation, so for battery manufacturers, except the cost problem, testing also is restricted relatively.
In addition, when user's battery breaks down and when sending the maintenance of former factory back to, the maintainer only can do maintenance according to the information that fail battery detects in the scene and judge, because battery can't write down the every battery information when using, thereby lack the use information of battery before fault, so the maintainer can't do to judge in detail for the failure cause of battery, make battery manufacturers lose battery quality is backward done the chance of further improving, and, relatively also cause the waste of maintenance cost because failure cause can't be put in order.
Summary of the invention
In order to solve above-mentioned prior art problems, the present invention proposes a kind of cell apparatus of built-in storage unit, to solve the existing problem that must use corresponding fixture just can carry out battery detecting and can't make fault front and back record to the information of battery of prior art.
Cell apparatus according to built-in storage unit of the present invention, it is by built-in storage unit and microprocessing unit, make when battery discharges and recharges, the battery information that microprocessing unit can measure sensing cell is stored among the storage element, therefore can make long-term detection record to the measurement information of battery.In addition, can allow fixture system in addition read battery information, therefore not need fixture also can detect operation by the output interface of sensing cell, the fetch interface of storage element or the fetch interface of microprocessing unit.
According to the embodiment of the invention, a kind of cell apparatus of built-in storage unit comprises power supply unit, sensing cell, microprocessing unit and at least one storage element.
Power supply unit is made up of at least one battery, has positive pole and negative pole, in order to discharge and recharge and to supply electric power.Sensing cell in order to the electric weight that measures power supply unit with discharge and recharge information, it is electrically connected at the positive pole and the negative pole of power supply unit, and have output interface for the electric weight of external computer system reads power supply unit with discharge and recharge information and obtain supply of electric power.Microprocessing unit is in order to the electric weight of handling the power supply unit that sensing cell measured and discharge and recharge information, and it is electrically connected at the output interface of sensing cell.Storage element in order to the electric weight that stores the power supply unit that sensing cell measured with discharge and recharge information, it is electrically connected at microprocessing unit, external computer system-readable is got the electric weight of the stored power supply unit of storage element and is discharged and recharged information.
In sum, by technological means of the present invention, can utilize storage element and microprocessing unit to solve the problem that general cell apparatus can't be made long-term detection record to the measurement information of battery, therefore utilize output interface and fetch interface can allow outer welding system read measurement information in addition, can solve and lack the problem that fixture just can't carry out battery detecting.
Relevant characteristics and implementation of the present invention, conjunction with figs. is described in detail as follows as most preferred embodiment now.
