supply-equipment (EVSE), vehicle-tohome (V2H), and V2G power-conditioner
operation tests and production inspections. Simulation is also be useful when it
is difficult to adjust the car parameters of
each automobile manufacturer.
It is difficult to use an actual battery for
each vehicle model due to various voltagecurrent characteristics and impedance
characteristics. In such cases, you can
reproduce and test each condition using
simulation. In addition to normal areas,
abnormal area tests can be safely verified.
An EVSE simulator can simulate the
EV quick charger specified in the standard specification of the quick-charging
station for electric vehicles (CHAdeMO).
The simulation range varies depending on
the component, but for the full set, the time
specified in the CHAdeMO standard can
be changed. GB/T charging and COMBO
charging are also supported. The charging method can be selected, and multiple
charging methods can be selected.
By using this, you can easily test abnormal conditions during EV charging.
For example, the timing and compliance
time specified in the CHAdeMO standard
can be changed, or the control line abnormality simulation can be executed at any
timing, and the abnormality related to the
soft error can be simulated. Tests can be
performed more efficiently than by using
actual machines.
