3 Terms and definitions
The terms and definitions specified in GB/T 17215.211-2006 apply to the document.
4 Configuration requirements and installation location
a) The charging metering device of AC charging spots shall be static multi-rate AC
active electric energy metering (hereinafter referred to as the electric energy
5.1.5 Functional requirements
5.1.5.1 Measurement of the electric energy
Electric energy metering shall measure the total active electric energy and the active
electric energy of the various rates.
5.1.5.2 Storage function
Storage function shall meet the following requirements.
a) The electric energy metering shall at least memory the total power energy and all
rates of electricity data of the first two months or the first two settlement cycle; the
default value of data archived separation time shall be at 24.00 of the last day of
each month, or at any time of 1st -28th of each month.
b) After power supply of electric energy metering fails, the stored data shall be kept for
at least 1 year;
c) Electric energy and other key charging information shall be stored in built-in security
module of electric energy metering to prevent key data from being tampered.
5.1.5.3 Clock and rate period
Clock and rate period shall meet the following requirements.
a) The built-in hardware clock circuit with temperature compensation function has the
automatic switching function among calendar, timing and leap year. Under the
reference temperature, the clock accuracy is ≤ ± 0.5s/d. The variation of the
accuracy of the clock with temperature shall be less than 0.15s/°C per 24h. The
clock can be timed under the programming state, and perform broadcast timing
under the non-programming state; the clock error of the broadcast timing shall not
be more than 5min, and it can be timed only once a day.
b) It shall have at least two sets of rate period; the automatic switching of the two sets
of rate period can be achieved via pre-setting the time. Each rate period can at least
set 2 time zones in the whole year; it can set at least 8-periods set within 24h; the
minimum time interval is 15min; the period can be set crossing the zero point.
c) Electric energy metering shall have a multifunction signal output interface, and with
the default output of second signal, which can be set by software to period switching
signal output.
