Conversion power in the charhing unit compared with high environment temperature is reduced, so that the charhing unit carries out work(
Less heat is distributed in rate transfer process, and the lower charhing unit of other environment temperatures is correspondingly improved and turns
Power is changed, under the premise of ensureing the charging ability of charging module, reduces the bulk temperature of the charging module.
Specifically, the ambient temperature value of each charhing unit is compared, maximum temperature value pair is obtained
The first charhing unit answered, and the based on generation first instruction control adjusts the charging of first charhing unit
Parameter reduces the conversion power of first charhing unit so that the first charhing unit reduce output electricity
Flow valuve reduces the heat generated in the transfer process of first charhing unit.
Step S1203：Based on the parameter preset of at least two charhing unit, the charger is provided
Charging current be divided at least two first electric currents；
Step S1204：Described at least two first electric currents are distributed at least two charhing unit, with
So that the charhing unit carries out power conversion based on the first electric current got generates the second electric current, and export
Second electric current is charged to the battery with being embodied as the battery.
Wherein, step S1203-1204 is consistent with the step S1101-1102 in embodiment 1, the present embodiment
In do not repeat.
To sum up, in a kind of charging method provided in this embodiment, further include：Each described charging of detection
The ambient temperature value of unit；According to the ambient temperature value of each charhing unit, maximum temperature is determined
It is worth corresponding first charhing unit, generates the first instruction, and sends described first and instruct to described first and fill
Electric unit, to indicate that first charhing unit adjusts charge parameter, so that first charhing unit drops
Low output current value.Using this method, it is detected by the environment temperature to charhing unit, to being in
The charge parameter of charhing unit in varying environment temperature is adjusted, and higher temperature is in realize to reduce
The conversion power of charhing unit in environment reduces its heat generated by power conversion, ensures charging mould
The equilibrium of group bulk temperature.
Attached drawing 13 is please referred to, is a kind of flow chart of charging method embodiment 3 provided by the invention, the party
