Vehicle-mounted DC/DC conducting between pond, battery pack charges to battery, so that battery remains certain electricity, it can be right
The other equipment normal power supply of vehicle.Vehicle-mounted DC/DC use is more frequent in the charging method, due to vehicle-mounted DC/DC compared to
It is more expensive for other kinds of DC/DC, moreover, being not easy to replace after damage, therefore, if vehicle-mounted DC/DC use is compared
Frequently, the service life of vehicle-mounted DC/DC can be reduced.
Utility model content
The purpose of this utility model is to provide a kind of chargers, are dropped for solving vehicle-mounted DC/DC using relatively more frequent
The problem of service life of low vehicle-mounted DC/DC.
To achieve the above object, the utility model proposes a kind of chargers, connect including the exchange for accessing electric main
Mouth, the first charging interface for being connected with battery pack, the second charging interface for being connected to the battery, the first AC/DC mould
Block, the 2nd AC/DC module and DC/DC module；The exchange side that interface connects the first AC/DC module is exchanged, the first AC/DC module
DC side is connected with the first charging interface, and exchange interface is also connected with the exchange side of the 2nd AC/DC module, the 2nd AC/DC module
DC side is connected with the second charging interface, and the first charging interface connects the second charging interface by DC/DC module.
In the case where charger to be connect with vehicle, the SOC of real-time monitoring battery pack and the SOC of battery work as electricity
The SOC of Chi Bao and the SOC of battery meet some requirements simultaneously, and battery pack passes through the DC/DC module in charger to electric power storage
Pond charging, and vehicle-mounted DC/DC is not used, the access times of vehicle-mounted DC/DC are reduced, the use of vehicle-mounted DC/DC is further increased
Service life.
Further, charger further includes for obtaining electric main access signal, accumulator electric-quantity and battery pack electricity
Monitoring modular, monitoring modular is connected with control module, control module control connection the first AC/DC module, the 2nd AC/DC module
With DC/DC module.
The automation that charging monitoring is realized by monitoring modular and control module is not necessarily to artificial monitoring, further to save
Human resources can also improve working efficiency.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model charger；
Fig. 2 is the schematic diagram of the utility model charger；
Fig. 3 is the work flow diagram of the utility model.
Specific embodiment
Charger embodiment:
As shown in Figure 1, 2, charger includes exchange interface, the first charging interface and the second charging interface, and exchange interface connects
It is connected to the exchange side of the first AC/DC module, the DC side of the first AC/DC module is connected with the first charging interface；Exchange interface also
The exchange side of the 2nd AC/DC module is connected, the DC side of the 2nd AC/DC module is connected with the second charging interface, and charger also wraps
DC/DC module is included, DC/DC module is connected with the first charging interface, the second charging interface.
Wherein, exchange interface is for accessing electric main, and the first charging interface with battery pack for being connected, the second charging
For mouth for being connected to the battery, the first AC/DC module is the AC/DC voltage changing module (battery pack) in Fig. 2, is used for electric main
Charged with direct current is converted into battery pack, the 2nd AC/DC module is the AC/DC voltage reduction module (battery) in Fig. 2, for that will hand over
Stream alternating current is converted into charged with direct current in battery, and DC/DC module is used to convert the voltage of battery pack to the voltage of battery
So that battery pack charging, in battery, DC/DC module is the DC/DC voltage reduction module in Fig. 2.
In the present embodiment, in order to realize that automatic control charge mode, charger further include monitoring modular and control module, prison
It surveys module and is connected with control module, control module control connects the first AC/DC module, the 2nd AC/DC module and DC/DC module,
Monitoring modular is used to monitor the access of electric main and the SOC of battery pack and battery, is used as other embodiments certainly,
In the case where personal monitoring, monitoring modular can also not have with control module, or be carried out using other interior control modules
It controls together, monitoring modular directly can also provide data by BMS monitoring modular, analyzed, controlled, in this way can also be into one
The saving space of step.
The course of work that charger charges as shown in figure 3, specifically:
1) SOC of the SOC and battery of charger monitoring modular real-time monitoring battery pack, while whether monitoring electric main
There is connection, is mainly realized and monitored by signal acquisition.
2) when lower limit value (setting charge threshold) of the SOC of monitoring module monitors to battery pack lower than setting, vehicle is mentioned
Show that battery pack needs to charge (by battery pack SOC numerical value in instrument or vehicle-carrying display screen or battery pack SOC progress bar or battery
Packet SOC numerical value shows etc. that display patterns are shown, redden with color state or show state with a certain in conjunction with progress bar
Frequency scintillation is prompted).After monitoring module monitors are connected to charger to electric main, data of the monitoring module to acquisition
After being handled, output services are instructed to control module, and charger is connected to (generally alternating current 220V) with external electric main, control
Molding block controls the first AC/DC module output high direct voltage (determining according to the voltage platform of battery pack) and charges to battery pack；Together
When monitoring modular also monitor the SOC of battery, when SOC < 100% (the second setting charging upper limit value) of battery, control mould
Block controls the 2nd AC/DC module output low-voltage direct (determining according to the voltage platform of battery) and charges a battery.Until prison
It surveys module monitors and reaches 100% to battery pack SOC and battery SOC, control system controls charger and stops charging, charger
It is disconnected with external electric main connected state.
For this charging process, it is to charge simultaneously to battery pack and battery, as other embodiments, is also possible to elder generation
It charges to battery pack, battery pack charges a battery full of after, until battery pack and battery are completely filled with.
3) when monitoring that (charger is filled not accessing electric main, electricity in the normal range (NR) of setting by the SOC of battery pack
Foot, does not need charged state, when being also possible to be greater than setting discharge threshold), but battery SOC is lower than the lower limit value (the of setting
One setting charging upper limit value) when, monitoring modular sends the signal to control module, and control battery pack is exported by DC/DC module
Direct current charges a battery, until monitoring that the SOC of battery reaches 100%, control module control battery pack stopping is filled
Electricity, charger and battery pack and battery disconnect.
The utility model essentially consists in the link circuit by charger, battery pack and battery, according to monitoring data
Control analysis is carried out, existing electric main is controlled and the positive input dc power and battery pack of battery pack, battery is reversely exported directly
The control of galvanic electricity, while can realize the function of high voltage direct current input conversion low-voltage direct output.
