Controller electrical connection.
10. charging assembly according to claim 9, which is characterized in that when the temperature of temperature sensor detection is more than
When preset value, charging current is reduced to preset range perhaps to stop described in charging or raising by controller
The flow of cooling water；When the flow of flow sensor detection is lower than preset value, charging current drops in controller
Down to preset range or stop charging.
