It is rapidly completed the replacing of battery, charges and safeguard, how to realize the standardization of battery case and the practical of rapidly replacing battery is
The key point that this pattern is universal.
(2) exchange trickle charge mode is provided electric energy, Vehicular charger to complete ac-dc conversion, charge power by alternating-current charging pile
The most little, the charging interval is usually 5～8h.Which charging current is less, it is possible to decrease battery heating in charging process
Amount, improves charge efficiency and extends the service life of battery, but its problem is that the charging interval is long.
(3) direct current fast charge mode is completed ac-dc conversion by off-board charger, and charge power is relatively big, the most often
The rule charging interval is 3～about 4h；Also within can providing 20min～2h.Quick charge, general charged electrical is provided with larger current
Stream is 150～400A.Regular big electric current quick charge can be greatly shortened battery, to the specification of charging connector, fills
The capacity of electricity facility it is also proposed higher requirement.It addition, electrical network will be impacted by the big curent change that quick charge causes,
Cause public electric wire net voltage pulsation, a large amount of harmonic waves that high-power charger produces, also can affect the quality of power supply of public electric wire net.
