The advent of advanced automobile technology has enabled the introduction of hybrid vehicle engine which is a combination of electric motor and gasoline fuel usage. Although the technology seems to support environment and provide ease of use to the consumer, the underlying risk associated with this is electrocution which could be fatal with the high rating of battery used in these vehicles. To minimise such risk, an economical and efficient monitoring system has been designed and developed to monitor voltage and current leakage from related cables on hybrid vehicles and warned stakeholders when the event necessitates it. Data collected shows alarming potential current leakage characteristic on overused cables when analysed.
