Claim 0:
1. An apparatus for detecting a height of a coolant leakage of a coolant flowing through a battery, wherein the height of the coolant leakage is along a first axis, the apparatus comprising;
first and second vertical connection lines;
a plurality of non-vertical electrical lines positioned within a battery pack, each non-vertical line extending along a respective axis that is not parallel to the first axis, and directly connecting a respective first node on the first vertical connection line to a respective second node on the second vertical connection line in an electrically parallel configuration; and
a plurality of resistors positioned within the battery pack, wherein each non-vertical electrical line includes at least one resistor of the plurality of resistors, wherein at least two resistors of the plurality of resistors are configured such that the at least two resistors are disposed at different heights along the first axis from a lower end of the battery pack toward an upper end of the battery pack, wherein a resistance of the at least two resistors varies by at least one resistor of the at least two resistors coming into contact with the coolant, wherein the at least two resistors are configured to be connected to and receive power from a power supply; and
a processor configured to:
receive an electrical signal from the at least two resistors; and
determine the depth of leaked coolant based on the electrical signal received from the at least two resistors.
