You could avoid a bit of copy paste / nesting here by adding a decorator, f.ex:

def io_error_safe_read(func):
    def wrapper(*args, **kwargs):
        try:
            return func(*args, **kwargs)
        except IOError:
            return
    return wrapper

then:

    @io_error_safe_read
    def get_voltage(self):
        system_voltage = (self.channel_voltage.convert_and_read() *
                          self.psm_to_battery_voltage)
        return system_voltage

    @io_error_safe_read
    def get_current(self):
        system_current = (self.channel_current.convert_and_read() - 
                          self.psm_to_battery_current_offset
                         ) * self.psm_to_battery_current_scale_factor
        return system_current

Would rename this to something a bit more descriptive 🐱

Verry well done.
Verry IMPORTANT that you delete the "key" and "key.gen" files as I can connect to you git account and push code without your concent and without knowing your password. I sugest you also dissable this key just in case and make a new one in private and write it down somewhere safe :)

If you want to further improve PSM system you can try and implement what Cristopher has commented. But that is ONLY if you feel confident that you know how to do those changes, otherwise no further improvements needed, this is a good code for me :)
