New-energy automobile module manual protection device
Technical field
The present invention relates to a kind of new-energy automobile module manual protection devices.
Background technique
It is a kind of new energy motor vehicles that the current whole world is being risen by the electric car being driven by electricity, according to knot
Structure principle is divided into mixed motivity type (PHEV) three categories of pure electric vehicle type (EV), oil electric mixed dynamic type (HEV) and outer plug-in again
Type, it is common to use lithium ion or lithium polymer storage battery make deposit and the output of electric power energy.And the supplement of electric energy relies on vehicle
Itself or external dedicated unit make charging input, therefore the power accumulator of electric car and charger device just constitute vehicle
The continuous important key device speeded ability and drive horsepower.
Since electric car is mainly by being driven by electricity, the operating voltage of electrical system is up to several hundred volts (Volt),
Electric current is up to several hundred amperes (Amp), if there is the short trouble for crossing vehicle-mounted electrical system, it will lead to the great of car crash
Accident occurs.For this purpose, standard GB/T/T 18384.2-2001 exists《Electric car safety requirements》Part 2, functional safety and
Clear stipulaties in the 5.5th article of emergency protection " overcurrent cutting-off device ":" when current is excessive, should use a circuit protector,
Disconnecting device or fuse disconnect at least one electrode of vehicle power supply (such as power accumulator) ".Exist again《Hybrid electric
Automotive safety requirement》Clear stipulaties in the 4.1.1.5 articles of GB/T 19751-2005:" power accumulator and motor circuit system are answered
It is protected by breaker and fuse, which should be able to connect in overcurrent as defined in Railway Car Plant, with power accumulator
Circuit there is short circuit in the case where, the automatic connection circuit disconnected with power accumulator ".
No matter the electric car of which kind of vehicle type structure and driving method, inside must have a Vehicular accumulator cell and a master
The electric energy storage and power-driven gear that motor is constituted, fuse are just mounted among this two major devices, take particularly important
Direct current electric channel and two-way short-circuit protection function.When automobile charges, fuse makees failure monitoring guarantor to the electric current of input battery
Shield, the overload for preventing circuit from occurring or short circuit current cause impact to damage battery;When the work of electric power storage tank discharge, fuse
Backward supervision protection is implemented to main motor and inverter, the overload or short circuit current for preventing electric system generation, which are returned, channels to electric power storage
Pond, the short circuit current for also preventing electrical system from occurring simultaneously damage charger and motor.
The shell of the big fuse of installation of existing protector is installed complicated, is bolted connection as overall structure,
And mini fuse silk is not included usually, so that mini fuse silk installation and replacement are inconvenient.In addition, being assembled without touch-proof setting
In the process, plug or socket are surprisingly touched, Danger Electric shock risk is had.
