Problems solved by technology

[0002] At present, the controller, air conditioner, PTC and other electrical components of the vehicle-mounted system of new energy vehicles are powered by the vehicle-mounted battery as a high-voltage power supply. Due to factors such as start-stop and vehicle load overload, the current will frequently appear from the vehicle battery voltage and current output to the load peak value of each branch, which is easy to damage the components
There are many fuse hardware used to protect the current and voltage of the electric parts in the car. Different fuses need to be electrically connected to the lines. There are many joints connected to the lines, which will easily lead to complicated installation and easy connection errors.
In addition, the intermediate fuse used by the on-board controller to carry current and protect the current and voltage is generally set in a single setting. When it is necessary to stabilize the current and shunt it, it can only be realized through this single set fuse, so that the constant current and voltage cannot be guaranteed. Unstable voltage can easily cause damage to the on-board controller
In the prior art, the current provided by the on-board battery is transmitted to various electrical components through direct connection with copper bars. However, such an electrical connection method cannot ensure constant current transmission, and unstable current may easily cause electrical components to be damaged.
Secondly, the installation of some electrical components or conductive sheets of existing vehicle-mounted controllers generally uses bolts or nuts to fasten, especially when some electrical components or conductive sheets are in a narrow space, the installation and Disassembly will be very troublesome
