Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing and example.
[0014] Such as figure 1 As shown, the current sensor auxiliary device with SOC calculation function consists of a current sensor 1, a protective housing 2, an AD acquisition circuit 3, a microprocessor 4, a CAN controller 5, a CAN transceiver 6, a CAN bus interface 7, and a program programming Interface 8, power supply module 9, low-voltage power supply input interface 10, 5V voltage reserve interface 11, electrical component locking and fixing clip 12.
[0015] The current sensor 1 is fixed in the protective shell 2 through the locking and fixing clip 12. The protective shell 2 is stamped and formed by aluminum-plastic plate or foil-plastic plate coated with plastic on the upper and lower surfaces. The entire protective shell can form a closed metal shielding structure, which is effective Prevent electromagnetic interference. The signal end of the current sen...
