's.The safety refers to, when power module is judged in idle state, then by its exchange input and direct current output from
It is cut off in its respective lines, without electrical contact.It can avoid after severe thunderstorm weather, lightning protection failure, power module
Whole or excessive burn observations, reduce the loss of extreme situation.
Intelligent power dynamically distributes technology, and with the configuration of four stakes of a cabinet, complete machine power is 200KW, 10 20KW
Power module often illustrates for the environment of the output of rifle maximum 187.5KW.When the passenger-transport electric vehicles need for having 50 seats simultaneously
Ask voltage 600V electric currents 130A, the mini-bus electric vehicle demand 620V electric currents 78A at 20 seats, the minibus electric vehicle demand electricity at 12 seats
Pressure 400V electric currents 52A and the electric motor car demand voltage 350V electric currents 52A at 4 seats charge at the same time, because each vehicle is equipped with
Battery capacity difference and demand voltage and electric current difference.Technology is dynamically distributed by intelligent power, first by 10
The module each car of 20KW point 1, then per car obtains 26A；Remaining 6 modules, then each point 1, each car obtains at this time
52A；Minibus vehicle and car have met greatest requirements at this time；Remaining 2 modules are then given into motor passenger vehicle and bus, this
Shi great Ba obtains 78A, has met its whole demand, and passenger traffic obtains 78A and in deficient need state.In charging process, work as vehicle
It is in fully charged state, current needs reduce, and reach the degree of a module when reducing, then can only assign them to and owe to need
The vehicle asked.
