Smart meter backup

Kelly Marie Angel

Hi this just a point of curiosity  but I was just wondering if smart meter backup batterys  are rechargeable I suppose the fact that we mite possibly be in for a winter of powercuts  peaked my interest

    I suspect the battery/capacitor is there not so much to preserve memory, but to allow the meter to communicate for a while into a power cut - i.e. to enable it to 'phone home' to report a supply loss to the DNO (who can then sometimes send someone out pronto to see who's been pulling their cut-out fuse without authorization..).

    If the mobile base station is on the same substation and is also off,  there  may not be a lot of point in phoning home either. It makes sense for one house where the incoming fuse has popped but during a ROTA cut I cannot see that feature being so useful.
    I do not know but if I was doing it the 'phone part' would be high on the list of things to put to sleep early on in the shutdown sequence perhaps in the first minute or two.  Perhaps one SMS outbound  and then off. Mind you not all designers think in terms of battery life - look at BT and the amazingly thirsty fibre to the premises kit that has to be always on.
