An electrical continuity detection system may comprise a plurality of identification tags placed on an electrically conductive object, and configured to respond to an injection signal on the electrically conductive object with a response, and a monitoring device coupled to the electrically conductive object and configured to generate the injection signal and an injection signal on the electrically conductive object, receive the response from one or more of the plurality of tags, receive a return signal from the electrically conductive object, determine a characteristic of the electrically conductive object based on the received responses and return signals, and generate a notification based on the characteristic.

Various embodiments described herein use a set of capacitor sets (e.g., capacitor banks) in a power backup architecture for a memory sub-system, where each capacitor set can be individually checked for a health condition (e.g., in parallel) to determine their respective health after the memory sub-system has completed a boot process. In response to determining that at least one capacitor set has failed the health condition (or a certain number of capacitor sets have failed the health condition), the memory sub-system can perform certain operations prior to primary power loss to the memory sub-system (e.g., preemptively performs a data backup process to ensure data integrity) and can adjust the operational mode of the memory sub-system (e.g., switch it from read-write mode to read-only mode).

A method for detecting an isolation fault in an isolation resistance between a positive and negative high-voltage bus rail and a vehicle chassis on a high-voltage propulsion side of a high-voltage system of an electric or hybrid-electric vehicle. The high-voltage system is split into a battery side and propulsion side by means of two high-voltage contactors located in the positive and negative high-voltage bus rails. The propulsion side includes first and second capacitors connected in series across the positive and negative bus rails, a common junction of the first and second capacitors connected to the chassis. The method supplies a low-voltage output to the positive and negative bus rails to charge the capacitors; and determines, based on charging current, voltage level or energy level of the capacitors, whether an isolation fault is present between the positive and/or negative high-voltage bus rail and the vehicle chassis on the propulsion side.
