6 FAQs about [High voltage battery pack equipotential connection]
What are EV equipotential bonding tests?
EV equipotential bonding tests, conducted post-installation or HV component replacement, ensure that all exposed conductive parts are at the same voltage.
What is a high-voltage battery pack?
Arranged in the chassis of a vehicle, the high-voltage battery pack consists of battery modules, which comprise many cell stacks, an ECU, which monitors and controls the battery condition, and functional parts, which switch on and off the power output, as well as connection parts, which connect these parts.
What is equipotential bonding?
Equipotential bonding in the (ev) high voltage system: A central element of high-voltage safety In any (ev ) high voltage training course, measuring equipotential bonding is a key exercise. Equipotential bonding within an HV (ev) component as well as equipotential bonding between any two high-voltage components in an electric vehicle.
Why do EV batteries need a low-profile connector?
The main challenge in the daily operation and charging of EV batteries is for OEMs and battery pack manufacturers to find a low-profile connector with low contact resistance at the individual contact points, resulting in reduced power loss and less heat.
What is an EV insulated return system?
EV system block diagram showing main components and chassis equipotential bonding EVs use an insulated return system so that there is no connection between the high-voltage circuits and the chassis. As part of the start-up process (when the vehicle is switched into ‘Ready’ mode) the on-board insulation monitor device runs a number of tests.
