Foreword
This standard replaces NB/T 33001-2010 " Specification for electric vehicle off-
board conductive charger". As compared with NB/T 33001-2010, in addition to
editorial changes, the main technical changes are as follows.
- DELETE the clause 7 “Inspection rules” and clause 8 “Test method” from
the original standard, such information can be found in NB/T 33008.1;
- In the new standard, ADD the clause 5 “Classification of chargers”, where
the chargers are classified from different points of views;
- The clause 8 “Marking, packaging, transportation and storage” of the new
standard corresponds to the clause 9 “Marking” of the original standard;
- In the clause 3 “Terms and definitions” of the new standard, MODIFY the
clause 3 “Terms and definitions” of the original standard; ADD 19 new terms
and definitions;
- In the clause 4 “Basic composition” of the new standard, MODIFY the
clause 4 “Basic composition” of the original standard; ADD the structural
block diagram;
- In the clause 6 “Functional requirements” of the new standard, MODIFY the
“communication function”, “human-machine interaction function”, “input
function”, “metering function” in the clause 5 “Functional requirements” of
the original standard; DELETE the “type of applicable battery”, “setting
method of charging", “low-voltage auxiliary power supply” from the original
standard; ADD the “insulation detection function”, “short-circuit detection
function of DC output circuit”, “vehicle plug lock function”, “pre-charge
function”, “emergency stop function”, “protection function”;
- In the clause 7 “Technical requirements” of the new standard, MODIFY the
“environmental conditions”, “power supply requirements”, “weathering
requirements”, “temperature rise requirements”, “protection requirements”,
“safety requirements”, “electrical insulation performance”, “output voltage
and current"; “charger’s efficiency and power factor”, “electromagnetic
compatibility requirements”, “mechanical strength”, “noise” of the clause 6
“Technical requirements” of the original standard; DELETE the “reliability
index”, “current flow imbalance” from the original standard; ADD the
“current ripple”, “constant power output”, “low-voltage auxiliary power
supply”, “requirements for charger output response”, “start output
overshoot”, “capacity coupling”, “standby power consumption”, “output
voltage, current measurement error”, “charge mode and connection
method”, “control guide circuit”, “charge control timing and flow”,
“mechanical strength”, “characteristics of mechanical switching device”,
Specification for electric vehicle
off-board conductive charger
1 Scope
