Emergency starting power supply with functions of automatically and synchronously recognizing high-and-low voltage of battery, warning and realizing switch-off protection

Abstract

The invention discloses an emergency starting power supply with functions of automatically and synchronously recognizing high-and-low voltage of a battery, warning and realizing switch-off protection. According to the emergency starting power supply, an input module is connected with an emergency starting power supply module and an information collection module separately; the emergency starting power supply module is also connected with the information collection module and an output module separately; the information collection module is also connected with the output module and a CPU processing module separately; the CPU processing module is also connected with a working power supply module, a synchronous switch module and an acousto-optic warning module separately; and the synchronous switch module is also connected with the working power supply module and the emergency starting power supply module separately. When the battery of the machine is over-discharged or over-charged, the system warns automatically; after the warning is sent out, if a user does not stop the operation, and the lower limit of discharging or the upper limit of charging of the battery is achieved, the system automatically and forcefully switches off all input and output functions; and meanwhile, the message is transmitted to the user in different acousto-optic ways.

Description

technical field [0001] The invention relates to the technical field of automobile emergency start power supply protection control system, in particular to an emergency start power supply for automatic synchronous identification of high and low battery voltages, automatic alarm shutdown protection. Background technique [0002] Although the general emergency starting power supply is equipped with a power indicator light or a voltmeter to measure the remaining battery power, it can only be detected by manually turning on its control switch. In actual use, users will not always press this switch to check The battery status of the machine causes over-discharge to cause low voltage or over-charging to cause over-voltage, but the machine cannot inform the user to stop using it in time, which often leads to a greatly shortened service life of the battery for emergency start-up power due to over-discharge or over-charge, and even will be directly damaged. Although there are some lo...

[0002] Although the general emergency starting power supply is equipped with a power indicator light or a voltmeter to measure the remaining battery power, it can only be detected by manually turning on its control switch. In actual use, users will not always press this switch to check The battery status of the machine causes over-discharge to cause low voltage or over-charging to cause over-voltage, but the machine cannot inform the user to stop using it in time, which often leads to a greatly shortened service life of the battery for emergency start-up power due to over-discharge or over-charge, and even will directly damage

Although there are some low-voltage automatic alarm function modules on the market, they are all directly connected to both ends of the battery, and are constantly monitoring the battery status, which increases the power loss of the battery, causing the machine to accelerate the power decline when no one is using it for a long time. As for the alarm, if a low-voltage alarm occurs in an unmanned state, the battery may be permanently damaged due to the accelerated loss of the alarm circuit within a day or two.

These control circuits need continuous power supply to work, resulting in accelerated battery self-discharge speed, which ultimately affects the maintenance time and life of the battery

[0003] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.
