Test circuit for determining electrical parameter of accumulator battery has clamp engaging battery terminal and precision resistor between connectors connected to evaluation circuits

摘要

The battery connection circuit with a measurement circuit (1) incorporates a clamp (2) with a tightening bolt (202) gripping a battery terminal. The clamp is connected to a first terminal (101) in contact with an end of a precision resistor (104). The other end of the resistor is connected to a second terminal (105) connected to an insulated (403) socket (401) forming a contact element (4) for a welded electrical cable (402). Terminals (12,13) are connected to evaluation electronic circuits (6-8).
