摘要

#CMT# #/CMT# The battery sensor has a terminal clamp (2) that is made of an electrically conductive material, for holding an electrical terminal particularly ground contact terminal of the battery. A low impedance current measuring resistor (4) is arranged for measuring the battery power which is charged or discharged through the battery. Several tongue structures (8-10) are arranged at a distance away from the terminal clamp, for providing mechanical support of the current measuring resistor at the terminal clamp. #CMT# : #/CMT# An independent claim is included for a battery. #CMT#USE : #/CMT# Battery sensor for battery (claimed) installed in motor vehicle. #CMT#ADVANTAGE : #/CMT# The enhanced operation of the battery sensor can be achieved by providing several tongue structures at specific distance away from the terminal clamp. The terminal clamp and tongue structures are made of same material, hence straightforward and inexpensive manufacture of the terminal clamp with tongue structures can be enabled. The difference in temperature between the connectors of the current measuring resistor can be measured, hence thermovoltage can be compensated favorably. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of the battery sensor. 2 : Terminal clamp 4 : Low impedance current measuring resistor 5,6 : Connectors 8-10 : Tongue structures 13 : Plastic sheathing.
