Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0021] The invention provides a built-in battery temperature measurement and identification circuit, which includes a temperature-sensitive resistor, one end of the temperature-sensitive resistor is connected to the negative pole of the battery, and the other end of the temperature-sensitive resistor is drawn from the battery; it also includes a capacitor, and the capacitor and the temperature-sensitive resistor are connected in parallel .

[0022] Because the temperature-sensitive resistor in the circuit of the built-in battery is incorporated into the capacitor, it can not onl...

Abstract

The invention discloses a built-in battery temperature measurement and identification circuit, battery, detection device and detection method, which belong to the field of electronic equipment. One end is drawn from the battery; it also includes a capacitor, which is connected in parallel with the temperature sensitive resistor; the detection device includes a signal generation module, a temperature detection module, an analog-to-digital conversion module, and a control module. The present invention can be implemented in a battery with only three pins. It achieves the purpose of having the four effects of temperature measurement, identification, anti-imitation, and low cost at the same time.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a temperature measurement and identification circuit of a built-in battery, a battery, a detection device and a detection method. Background technique [0002] Due to many reasons, the current mobile phone battery uses three pins, the positive pole and the negative pole respectively occupy two pins, and one pin can be used as a temperature measurement pin, and can also be used to identify the battery type (such as Use different resistors to represent different battery models) and / or pins of manufacturers (for example, each manufacturer can use different resistors to represent its own products); under this three-pin architecture, if you want to use A three-pin battery can read temperature and identification information at the same time by using a built-in chip in the battery, and use a single bus to output temperature and identification information at the same time. Obviousl...
