72V electric vehicles can be charged with 60V chargers, but they are not fully charged. 1, 72V battery charging termination voltage is 72*1.2=86.4V.. 2, 60V battery charging termination voltage is 60*1.2=72V, the actual charging voltage will be a little higher, but it is obviously not satisfied with the battery. 3. Charging principle: When the battery power is low, the constant current charging mode is adopted, that is, charging at a constant current. At this time, the power consumed by the control circuit is relatively small compared with the charging mode. When the voltage reaches a certain value, the charging mode is changed to constant voltage charging mode. Until the charging voltage is equivalent to the battery voltage, in this process, the consumption ratio of the control circuit is gradually increasing, so there is a four-stage, five-stage... In order to reduce unnecessary consumption, in the process of constant voltage charging, constant current charging is carried out (the more segments, the higher the efficiency, and the more complex the control). When the charging voltage is equivalent to the battery voltage, the so-called \"trickle\" charging is entered, and this process is more important to enrich the battery, but the electrical efficiency is also the lowest.
The 60v charger cannot charge the 72v electric vehicle, otherwise it will cause the electric vehicle battery to fail. When charging an electric car, be sure to use the right charger. It is recommended to use the original electric vehicle charger to charge the electric vehicle battery.
