Power source control chip and control method thereof

Abstract

The invention discloses a power source control chip and a control method thereof and relates to the technical field of primary battery control. A plurality of electrodes a are arranged on one side ofthe power source control chip, a plurality of electrodes b, a signal electrode c, a signal electrode d, an electrode e and an electrode f are arranged on the other side of the power source control chip, a sensor, an analog-digital converter, a core process, a MOS driver, a MOS transistor and a secret key unit connected to the core processor through an integrated circuit, the sensor, the analog-digital converter, the core processor, the MOS driver and the MOS transistor are sequentially connected through an integrated circuit, the electrodes a and the electrodes b are connected to two poles ofthe MOS transistor through an integrated circuit respectively, the electrode e and the electrode f are connected to an integrated circuit to form a power supply electrode of the same, and both the analog-digital converter and the core processor are connected to a double-wire interface connected with an outside battery management unit. By the power source control chip, the problem that existing individual primary batteries do not have functions of detecting inside temperature and pressure in real time and of controlling permission-type discharging and the problem that the individual primary batteries do not have signal encryption for controlling power source output can be solved.

Description

technical field [0001] The invention relates to the technical field of primary battery control, in particular to a power supply control chip and a control method thereof. Background technique [0002] In the current global technology for single primary batteries, disposable batteries only provide discharge functions, and storage batteries have charging and discharging functions. This type of single primary battery only adds a very small amount of sensors pasted on individual primary batteries when forming a battery pack. On the surface of the battery, there is no temperature detection sensor inside, and it does not have the internal temperature detection function. It cannot realize the online detection of the internal temperature during the charging and discharging process, and it cannot fully detect the charging and discharging overheating state of the battery pack, resulting in overheating. Property damage due to spontaneous combustion. [0003] At the same time, this typ...
