3.Operate Condition and requirement
working condition
1) Prevent the rain, water, avoid direct sunlight ,away from the sources of charger,such us fire source,
combustible gas,rain,snow smoke,sand-dust ect.
2) Operating temperature:-20
℃
~45
℃
3) Operating humidity:5%~95%
4) Operating altitude:<=2000m
Safety requirement
1) Distribution power needs to meet the requirement of battery charger power. Wire diameter of AC
input cable should be selected appropriately according to the battery charger power. For example, if
the battery charger power is 45kW, the phase line should be Chinese standard copper wire with
sectional area larger than 16
㎡
(Awg 5/0), and the ground line should be Chinese standard copper
wire with sectional area larger than 4
㎡
(Awg 11).
2) In the external distribution box, the circuit breaker of cable connecting to AC charger should have
electric leakage protection function.
3) The ground line must be connected, and the grounding performance
should be well.
4) Before charging the electric car, please be sure to confirm whether the electric car charging voltage
rating and auxiliary power voltage match the choice of DC charger model. The power battery voltage of
passenger car is usually below 450V and its auxiliary power is 12V. The power battery voltage of
electric bus with 6m above is 500V-750V and its auxiliary power is 24V.
