In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, it can also realize the application technical solution claimed.
The first embodiment of the present invention is related to a kind of test equipments of battery short circuit.In the test equipment to battery short circuit
Before being described in detail, it is necessary first to which explanation, lithium ion battery generally includes battery core and protection board, and protection board is usual
Including control IC (integrated circuit), resistance, capacitance and MOS switch and some additional devices, such as FUS, PTC (positive temperature coefficient heat
Sensitive resistor), NTC (negative temperature coefficient thermistor), memory etc..The control IC and memory of protection board refer to for storing
Control instruction is enabled and sent out to MOS switch, is the core of entire battery protecting plate.Protection board be located at battery core and external circuit it
Between, the conducting of MOS switch and disconnect substantially is exactly battery core and external circuit conducting and disconnection, therefore verification protection board can
It is exactly the reliability for verifying MOS switch in property great significance.Specifically, as shown in Figure 1：Figure label 11 is protection board function
Simplification figure, B+, B- indicate that the positive and negative electrode interface of battery core, P+, P- are the positive and negative electrode interface of protection board respectively respectively, and S1 indicates outer
The simplification figure of portion's short circuit current, S2 indicate the simplification figure of MOS switch.(i.e. the test circuit of battery is not short-circuit), S2 are disconnected in S1
When in normal operating conditions (closure), the voltage U of battery core is equal to the pressure difference U1 at the both ends B- and P+；And it is closed (i.e. battery in S1
Test circuit short circuit), when S2 be in guard mode (disconnection), the pressure difference U2 of the voltage U of battery core equal to the both ends B- and P-.
