Sub panels are never to have the neutral and ground bonded.
The neutral does have some potential difference to ground depending on the load but it should never exceed 10 volts during normal conditions, ideally it's only around 3 volts.
Balanced load will also help reduce the voltage difference to ground on the neutral.
