For safe operation we recommend that all EVs should be fitted with earth leakage detection systems. This earth leakage detector should be used to monitor whether there is any earth leakage on your EV before you switch on the high voltage power. It is specifically designed for use on 96V systems with 12V ancillay circuits. Systems for other voltages can be supplied if required - please enquire with your requirements.
Connect this system to your EV's key switch input wiring and to the main positive and negative power cables. When you turn your EV's ignition key on, a timer will activate the detector system which will check briefly whether there is any earth leakage. The included relay should be connected so that it interupts the key switch input connection to the controller before start-up to safely immobilise the EV in the event that there is any earth leakage. At the same time the detector can activate an alarm to signal that there is an earth leakage fault in the EV's high voltage power system.
This earth leakage detector can immobilize the vehicle at start-up and be linked to an alarm and signal if any part of the high voltage electrical system's insulation breaks down or any part becomes unintentionally connected to the vehicle's chassis. All EVs and Hybrids produced by large manufactureres include earth leakage detection and in many countries around the world it is now mandatory to fit earth leakage detection on your EV.
