Abstract
A device for measuring electrical parameters, in particular an insulation voltage, of a battery cell, comprises at least one probe including a conductor configured for electrically coupling to a voltage sensor; wherein the conductor has an arced contact surface configured for engaging the battery cell to be measured; and a biasing member configured for mounting the conductor resiliently in a first direction.
Claims20
A device for measuring at least one electrical parameter of a battery cell, comprising:
- at least one probe including
- a conductor configured to be electrically coupled to a current- and/or voltage-sensor, wherein the conductor has an arced contact surface configured to engage the battery cell to be measured;
- and
- a biasing member configured to move the conductor along a first axis, wherein the conductor is connected to the biasing member and wherein the biasing member is configured to resiliently bias the conductor in a forward direction of the first axis.
A method for measuring at least one electrical parameter of a battery cell comprising a sealed edge portion the method comprising:
- electrically coupling a conductor to at least one of a current sensor or a voltage sensor, wherein the conductor has an arced contact surface configured to engage the battery cell;
- and
- activating a biasing member to move the conductor along a first axis into engagement with the sealed edge portion, wherein the biasing member resiliently biases the conductor in a forward direction of the first axis.
The method of claim 19, further comprising measuring the electrical parameter of the battery cell while the conductor remains in engagement with the at least sealed edge portion.
The method of claim 19, wherein the biasing member causes the conductor to move along the sealed edge portion of the battery cell in a direction crosswise from the first axis such that the arced contact surface moves along the sealed edge portion of the battery cell.
