Description

A kind of Vehicular display device that is applicable to electronlmobil

[technical field]

The utility model relates to a kind of Vehicular display device, specifically a kind of Vehicular display device that is applicable to electronlmobil.

[background technology]

Along with the development of electronlmobil, need the electronlmobil Vehicular display device to have more function.At first, data such as a large amount of cell pressures, temperature, electric current need to show in real time, and the situation of electrolytic cell that made things convenient for driver and service personnel guarantees the safe handling of battery.Secondly, the normal CAN of employing bus sends data on the electronlmobil, and vehicle-carrying display screen need have the CAN interface and come swap data.At last, the data of batteries of electric automobile and vehicle operating are significant to analyzing battery and vehicle operation situation, so wish to preserve these data.

[utility model content]

In view of this, be necessary to provide a kind of and can check electronlmobil internal cell situation, can communicate the Vehicular display device that is applicable to electronlmobil with data exchange with electronlmobil internal cell management system.

A kind of Vehicular display device that is applicable to electronlmobil, comprise a read-out main body, described read-out body interior circuit connects with electronlmobil internal cell management system by the CAN communication circuit, and being connected with on the read-out main body can be to the USB of outside memory transfer battery data driving circuit.

As the improvement to such scheme, described read-out body surfaces is equipped with the touch TIP.

Wherein, described read-out body interior circuit comprises that the homepage module, battery temperature display module, fault alarm display module, charge information display module, the parameter that show homepage are provided with module and data storage display module, and each module is all controlled by the main control chip of read-out body interior circuit.

The utility model adopts special-purpose read-out to show by the battery related data of data circuit with the collection of electronlmobil internal cell management system, can report to the police, show the battery abnormal condition, can the parameter of battery management system be provided with, and can related data transmission be convenient to analyze to external memory storage by the USB driving circuit, entire display screen is attractive in appearance, clear, and is practical, convenient.

[description of drawings]

Fig. 1 is the utility model embodiment integral structure scheme drawing;

Fig. 2 is a present embodiment read-out body interior circuit theory scheme drawing;

Be further detailed below in conjunction with accompanying drawing.

[specific embodiment]

At the defective that prior art exists, the utility model embodiment has proposed a kind of more perfect solution, in detail shown in accompanying drawing 1～2.

The Vehicular display device that is applicable to electronlmobil that this programme disclosed can make things convenient for, clearly provide the related data information of electronlmobil internal cell.This Vehicular display device comprises a read-out main body 1, read-out body interior circuit connects with electronlmobil internal cell management system 6 by CAN communication circuit 2, and be connected with on read-out main body 1 can be to the USB of outside memory transfer battery data driving circuit 3.For the ease of input, read-out main body 1 mounted on surface has the TIP 4 of touch.

Wherein, read-out main body 1 internal circuit comprises that the homepage module 51, battery temperature display module 52, fault alarm display module 53, charge information display module 54, the parameter that show homepage are provided with module 55 and data storage display module 56, and each module is all controlled by the main control chip 11 of read-out body interior circuit.

Homepage module 51 is used for showing main battery information, comprises total voltage, total current, SOC, also has maximum voltage in the whole Battery pack, minimum voltage, highest temperature, minimum temperature and them to be positioned position in the battery system.Battery temperature display module 52 shows the voltage data and the temperature data of all batteries in detail, makes people can both well understand the voltage temperature data of every case battery.Fault alarm display module 53 reminds the driver that fault is handled real-time the showing of time of fault type, failure code and the generation of the current existence of battery system.54 pairs of charge informations of charge information display module show, the process of charging significant data is contrasted in real time, make people intuitively understand process of charging, guarantee battery is carried out safe charging.Parameter is provided with module 55 and can be provided with and reads by some parameters that touch 4 pairs of battery management systems 6 of TIP, is convenient to battery management system 6 is debugged and safeguarded.Data storage display module 56 is used for all battery datas are preserved.When needs are preserved data, plug USB flash disk at USB driving circuit 3 sockets, click the corresponding button by touching TIP 4 then, this moment, the data of battery will be kept in the USB flash disk.These data all are useful to the running condition analysis of the analysis of battery condition of service, battery performance analysis, electronlmobil.

In this programme, each module that related electronlmobil internal cell management system, the CAN communication circuit that is adopted, USB driving circuit, touch TIP, main control chip and read-out body interior are adopted all can adopt existing ripe circuit layout, does not give unnecessary details one by one at this.

The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, therefore, the protection domain of the utility model patent should be as the criterion with claims.
