一． System diagram
According to customer requirements, configuration of the system chart is as follows, for reference only.
二． system description
In order to protect batteries, there are several purposes to string Schottky diodes in the battery circuit. There are several purposes: first, to avoid frequent battery charging and increase cycle life; the two is to avoid overcharging on the downhill or fast brakes, charging the battery and protecting the battery.
Battery rated voltage 288V, battery rated discharge current 45A, rated discharge power 12.9KW, motor peak power 30KW, in order to protect battery but increase battery life, configure capacitance power >20KW, in this system, battery discharge power is controlled at about 10KW.
