3 Terms and definitions
Terms defined in GB/T 19596 and GB/T 18487.1 as well as following definitions and terms
apply to this standard.
3.1
On-board charger
Refers to a device that installed on the electric automobile, and can converted the power
of the public grid into direct current required by the on-board energy storage device and
can charge the on-board energy storage device.
3.2
Charging efficiency
The percentage of the ratio of the on-board charger DC output power and the AC input
active power.
3.3
Total harmonic distortion (THD)
The square-root of sum of squares of the ratio of the 2-th – 40-th harmonic current
component AND the fundamental current.
Where.
Im — The n-th harmonic current component.
I1 — Fundamental current.
protection value, it shall turn off the output and give the alarm. After troubleshooting, it
shall have the automatic recovery function.
6.4.3.3 Short-circuit protection.
When the output short circuit happened before starting the on-board charger, it shall not
start after powered on and shall give alarm. During operation, if the output short circuit
happened, the output shall be turned off and give alarm. After troubleshooting, the
on-board charger shall be able to work normally.
6.4.3.4 Over-temperature Protection.
When the temperature at the temperature sampling point of the on-board charger exceeds
the set value of over temperature protection, it shall automatically enter into the state of
over temperature protection, and shall run at a reduced power or shut down. After the
on-board charger’s temperature returns to normal, it shall have the automatic recovery
function.
6.4.3.5 Reverse-connection Protection.
For the on-board charger of which the output port does not have anti-reverse, when the
DC output terminal and the polarity of on-board energy storage device are connected
reversely, it shall not be started and shall give alarm. After troubleshooting, the on-board
charger shall be able to work normally.
6.4.3.6 Potential equilibrium and ground protection.
The resistance between conductive parts that are directly accessible to the human body in
the on-board charger and the potential equilibrium shall not be greater than 0.1. The
on-board charger grounding point shall have obvious grounding sign.
6.4.3.7 Power-off protection.
The on-board charger shall have the function of cutting off the power supply quickly in the
exceptional circumstances.
6.4.4 Low voltage power supply function.
For the on-board charger with a low-voltage auxiliary power, the low voltage auxiliary
power supply shall provide a DC voltage with a nominal value of 12V or 24V, and the DC
voltage ripple factor shall be less than 1%.
7.4.3.2.2 Output under-voltage protection.
At the voltage and frequency range conditions specified in 6.3, start up on-board charger
to make it run at constant current, and reduce the load resistance, making the output
voltage of the on-board charger lower than the DC under-voltage protect...
