Embodiment Construction

[0013] Relevant detailed description and technical content of the present invention, now just explain as follows with respect to matching drawing:

[0014] The invention provides a protection device, which can ensure that the battery output from the vehicle battery is supplied to the load in the vehicle, and can quickly suppress the interference of the unstable high current of the battery and abnormal electrostatic discharge and allow the protection device to be used repeatedly without replacing it. Electronic protection components (such as fuses), and at the same time, it can avoid the damage of electronic parts in the car caused by the reverse connection of the battery of the vehicle.

[0015] see figure 1 , which is a schematic diagram of a protective device for a vehicle battery in a preferred embodiment of the present invention. The protection device 50 described in this embodiment is arranged between the vehicle battery 30 and the vehicle equipment 40, and is used to pr...

Abstract

The invention discloses a vehicle battery protection device which is arranged between a vehicle battery output port and a vehicle device. The protection device comprises a transient diode, a diode and a battery noise suppression unit; the transient diode is connected to the vehicle battery output port; the diode is connected to the transient diode and the vehicle battery output port; the battery noise suppression unit is connected to the diode and a vehicle device input port. The transient diode in the protection device can restrict unstable current in a safe potential difference so as to ensure the service life of the vehicle device; meanwhile, the interference of the static electricity on the vehicle device can be prevented by arranging the battery noise suppression unit; and the reliability of the vehicle device is improved.

Description

technical field [0001] The present invention relates to a protection device, and more particularly to a protection device in a vehicle battery having a high current to suppress battery instability. Background technique [0002] Unstable current flow is the cause of damage to electronic circuits. These currents usually come from the switching moments of electrical equipment. For the vehicle, there will be a large amount of electricity left when the car is started. For the vehicle equipment inside the vehicle, this unstable high current will easily damage its internal components. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a protective device for a vehicle battery, which quickly suppresses unstable large currents through transient diodes, so that the protective device can withstand multiple unstable large currents without replacement any electronic components. [0004] In order to solve the above technical p...
