Abstract

An apparatus may include a controller and a relay device for measuring voltages associated with a battery and determining resistances associated with the battery that can be used to determine whether there is a battery ground associated with the battery. The relay device may comprise one or more switches that may be coupled to the battery for measuring the voltages. The relay device may be configured to implement an automated configuration sequence of one or more configurations of the one or more switches in order to the measure voltages. The controller may determine resistance values based on the measured voltages values. Based on comparing the resistance values to a threshold, one or more battery grounds of the battery may be determined and a notification may be output based on the detected one or more battery grounds.

Dependent claims

An apparatus comprising:

a relay device comprising one or more switches coupled to a battery under test, wherein the relay device is configured to:
determine, based on a first configuration of the one or more switches, a value of the first voltage associated with the battery under test,
determine, based on a second configuration of the one or more switches, a value of the second voltage associated with the battery under test,
determine, based on a third configuration of the one or more switches, a value of the third voltage associated with the battery under test, and
send data indicative of the value of the first voltage, the value of the second voltage, and the value of the third voltage;
and
a controller in communication with the relay device, wherein the controller is configured to:
receive data indicative of the value of the first voltage, the value of the second voltage, and the value of the third voltage,
determine, based on the value of the first voltage and the value of the second voltage and the value of the third voltage, a value of a first resistance associated with the battery under test and a value of a second resistance associated with the battery under test, and
cause, based on at least one of the value of the first resistance or the value of the second resistance, output of at least one notification.
