What is a Current Leakage in Electric Vehicles (EVs)?

Let us make the concept of current leakage in an electric vehicle simple. 

So, for example, we have the most basic electrical circuit comprising a customer, a switch, and a battery. You connect the consumer to the battery so it can be switched off or on at will. If you close the electrical circuit with a switch, electric current will flow through it. The consumer will work, and the battery gets discharged. When you break the circuit with a switch, no electric current will flow through it. The consumer will not work, and the battery will lose its stored energy.

Meanwhile, the electronics, mass disconnect button, or ignition lock can act as the switch in vehicles. You break the electrical circuit by moving the ignition switch to the extreme position before parking the car. It also works if the machine has electronics that go to sleep mode or standby. Nevertheless, despite these measures, the current in the circuit still flows. Why is that possible?

The appliances that go to hibernation or standby mode continue to use up power. Next, the ignition switch is not a major switch; it does not turn off everything. The car is de-energized when the mass button is turned off or the terminal is removed from the battery.

Now let us divide the leakage current into increased and normal. If the battery’s energy while the car is parked is spent on the operation of the necessary devices, this is a normal current leakage. Such comprises a sleeping radio tape recorder, a burglar alarm, etc. Increased current leakage indicates that battery power is being wasted, such as accidentally leaving the lights on.
