Description

Technical Field

[0001] The utility model relates to the technical field of shunts, in particular to a novel battery shunt. Background Art

[0002] At present, the power battery system needs to detect the charge and discharge current value. In order to control the cost, a shunt is generally used to detect the charge and discharge current value of the power battery system. A shunt is an instrument for measuring direct current, which is made based on the principle that a voltage is generated at both ends of a resistor when a direct current passes through the resistor.

[0003] However, when using a new type of battery shunt, the shunt is susceptible to electromagnetic interference generated from the outside or inside, causing interference to the shunt and the circuit connected to it. Therefore, in the current measurement, the electromagnetic interference will affect the accuracy of the measurement results, and due to the leakage of radiation, the shunt will have an adverse effect on the surrounding environment during use. At the same time, the shunt is prone to loosening during use, which greatly reduces the accuracy of the measurement. Due to the presence of resistance, a certain amount of heat will be generated. If the heat cannot be effectively dissipated, the temperature of the shunt body will rise, which will affect its performance and stability, resulting in low current value measurement accuracy of the shunt.
