摘要： A current sense resistor and a method of manufacturing a current sensing resistor with temperature coefficient of resistance (TCR) compensation is disclosed. The resistor has a resistive strip disposed between two conductive strips. A pair of main terminals and a pair of voltage sense terminals are formed in the conductive strips. A pair of rough TCR calibration slots are located between the main terminals and the voltage sense terminals, each of the rough TCR calibration slots have a depth selected to obtain a negative starting TCR value observed at the voltage sense terminals. A fine TCR calibration slot is formed between the pair of voltage sense terminals. The fine TCR calibration slot has a depth selected to obtain a TCR value observed at the voltage sense terminals that approaches zero. The resistance calibration slot has a depth selected to calibrate a resistance value of the resistor.

摘要： A circuit (200') for use, e.g., as current sense amplifier in a DC-DC converter in a hybrid vehicle comprises:
a first input node (INP) and a second input node (INM), configured to have an input voltage signal (IHSEN, ILSEN) applied therebetween,
a floating-ground input stage (IS) configured to operate between a first supply voltage (VLOW+5V) and a second non-zero supply voltage (VLOW) and to convert into a current signal the input voltage signal applied between the first input node (INP) and the second input node (INM), and
an output stage (OS) configured to receive the current signal from the floating-ground input stage (IS) and to convert the current signal back to an output voltage signal (AMPoutP, AMPoutM) referred to ground (GND).
The output voltage referred to ground is a replica of the input voltage signal applied between the first input node (INP) and the second input node (INM).

摘要： The object of the present invention is to improve the accuracy of electrical measurement devices (4) utilizing shunt resistors (8), in particular, by reducing the temperature influenceability of the measurement. The object is achieved by a contact element (1) for connecting an electrical sensor (6) to a shunt resistor (8) in an electrically conductive manner, wherein the contact element (1) comprises a first side (12) and a second side (14), the second side (14) facing away from the first side (12), wherein, on the first side (12), a terminal section (18) of the contact element (1) for connecting the contact element (1) to the electrical sensor (6) is arranged, wherein, on the second side (14), at least one contact surface (26) for abutting against a surface (28) of the shunt resistor (8) protrudes, wherein the contact element (1) comprises an attachment section (34) for fastening the contact element (1) to the shunt resistor (8), and wherein the at least one contact surface (26) is spaced apart from the attachment section (34) in a radial direction (60). Due to the at least one contact surface (26) being spaced apart from the attachment section (34), it is possible to electrically contact the shunt resistor (8) by means of the at least one contact surface (26) at a location as close as possible to temperature insensitive resistive elements (68) of the shunt resistor (8). Thereby, the influence that any other components of the shunt resistor (8) have on the resistance value of the conductive path between the contact element (1) and the resistive elements (68) of the shunt resistor (8) is eliminated or at least minimized. The object is further achieved by a shunt assembly (2) comprising the inventive contact element (1) as well as by an electrical measurement device (4) comprising the inventive shunt assembly (2).

摘要： The present application provides a battery sampling chip and a battery management system. The battery sampling chip includes: a selector module, including a first multiplexer and a second multiplexer, wherein the first multiplexer and the second multiplexer are both used to collect status data of a first group of cells; an analog-to-digital conversion module, connected with the first multiplexer and the second multiplexer; and a data control module, used to send alarm information when converted status data sent by the analog-to-digital conversion module are not received within a preset duration. Through redundancy design of the multiplexers, whether the selector module fails or is abnormal can be effectively judged, thus avoiding the battery management system including the battery sampling chip from monitoring incorrect status data. Compared with the prior art, the battery sampling chip provided by the embodiments of the present application enhances safety of the battery management system while improving its own reliability.
