With reference to Fig. 2 to Vehicular battery current measuring device and current measurement according to an embodiment of the invention
Illustrate with resistance component.Fig. 2 illustrates that Vehicular battery electricity according to an embodiment of the invention
Flow measuring apparatus and the schematic diagram of current measurement resistance component.
Reference Fig. 2, according to an embodiment of the invention Vehicular battery current measuring device, including: car
Ground terminal 100；The cathode terminal 200 of battery；And resistance component 300.The earth terminal of vehicle
Son 100, as the part on the chassis of vehicle, can form ground connection.
Resistance component 300, is placed between the cathode terminal 200 of ground terminal 100 and battery, from
And the ground terminal 100 cathode terminal 200 with battery of connecting.
This resistance component 300, including: main body B, it is placed in ground terminal 100 and the electricity of vehicle
Between the cathode terminal 200 in pond, thus the ground terminal 100 cathode terminal 200 with battery of connecting；
Multiple measurement terminal P1, P2, P3, P4, be connected on the surface of main body, for measuring electric current.
Main body B, as in figure 2 it is shown, its cross-sectional area is along with the portion from contact ground terminal 100 separately
Begin, can become the least closer to the part contacted with the cathode terminal 200 of battery.
Multiple measurement terminal P1, P2, P3, P4, make each measurement terminal P1, P2, P3, P4 and connect
Distance between ground terminal 100 (or make the cathode terminal of each measurement terminal P1, P2, P3, P4 and battery
Distance between son 200) differently from each other dispose.
As it has been described above, the cross-sectional area of resistance component 300 is along with, from the beginning of at ground terminal 100, getting over
Can become the least at cell cathode terminal 200, and resistance value is inverse proportion with cross-sectional area, because of
Resistance value R1 between this first measurement terminal P1 and second measurement terminal P2, the first measurement terminal P1
And resistance value R2 between the 3rd measurement terminal P3, the first measurement terminal P1 and the 4th measurement terminal P4
Between resistance value R3 can be respectively different.Therefore, the first measurement terminal P1 and the second measurement terminal P2
