Abstract
The invention discloses a kind of method that fuel-engined vehicle instrument changes electric vehicle instrument into, relate to the method that fuel-engined vehicle instrument changes electric vehicle instrument into.What export in battery management system is the CAN signal that digital signal exports originally, exports a road artifical resistance amount on this basis; The wire of instrument on fuel-engined vehicle is directly accessed the resistive mode analog quantity mouth of battery management system, the value of battery status is become analog output to analog output port by battery management system simultaneously, the fuel consumptio indicator display now in fuel-engined vehicle instrument just shows the pointer display of battery status; The mean temperature of battery, by analog output, by battery draw temperature simulation amount mouth in the engine water temperature sensor port of fuel-engined vehicle instrument access battery management system, Engine Coolant Temperature table just shows the pointer display of battery mean temperature.The present invention enables the driver of traditional custom auto meter display mode accept the state display of batteries of electric automobile smoothly, reduces repacking cost when conventional fuel oil automobile repacking is electronlmobil simultaneously.
Description
Technical field
The present invention relates to the method that fuel-engined vehicle instrument changes electric vehicle instrument into.
Background technology
Current pure electric vehicle is mainly by conventional fuel oil automobile repacking, in retrofit process, install battery pack additional, battery pack state display mainly by install additional display screen realize, namely a screen is added at the instrument desk of fuel-engined vehicle, change traditional instrument desk layout, cause the chaufeur of orthodox car to have a lot of inadaptable, the information shown this display screen is insensitive.
Summary of the invention
The invention provides a kind of method that fuel-engined vehicle instrument changes electric vehicle instrument into, the driver of traditional custom auto meter display mode is enable to accept the state display of batteries of electric automobile smoothly, and utilize the characteristic of conventional fuel oil auto meter, driver is provided to the prompting being convenient to accept.
For solving the problem, the present invention adopts following technical scheme: comprise battery management system and auto meter, auto meter there are water thermometer and fuel consumptio indicator, battery management system have SOC analog output and battery mean temperature analog output input to auto meter;
What export in battery management system (1) is the CAN general line signal (2) that digital signal exports originally, export road SOC analog output (3) on this basis, this battery status change scope is consistent with the pointer variation range of fuel-engined vehicle, the wire of fuel-engined vehicle instrument (5) is directly accessed SOC analog output (3) one end of the resistive mode analog quantity of battery management system, the value of battery status is become analog output to analog output port by battery management system simultaneously, fuel consumptio indicator (7) display now in fuel-engined vehicle instrument just shows the pointer display of battery status,
By battery mean temperature by analog output (4), by battery draw temperature simulation amount mouth in the engine water temperature sensor port of fuel-engined vehicle instrument access battery management system, then the Engine Coolant Temperature table (6) in traditional vehicle instrument just shows the pointer display of battery mean temperature.
The beneficial effects of the utility model are:
One, in repacking electronlmobil, utilize the characteristic of conventional fuel oil auto meter, driver is provided to the prompting being convenient to accept, enable driver accept the status displaying information of batteries of electric automobile smoothly;
Two, make full use of conventional fuel oil auto meter, the function that this instrument is not used in electronlmobil makes full use of.
Three, reduce when conventional fuel oil automobile repacking is electronlmobil and reequip cost.
Accompanying drawing explanation
Fig. 1 is principle of the invention figure.
Nomenclature in figure: battery management system 1; CAN signal 2; SOC analog output 3; Battery mean temperature analog output 4; Auto meter 5; Water thermometer 6; Fuel consumptio indicator 7.
Detailed description of the invention
As shown in Figure 1, a kind of fuel-engined vehicle instrument changes the method for electric vehicle instrument into, comprise battery management system and auto meter, auto meter has water thermometer and fuel consumptio indicator, battery management system has SOC analog output and battery mean temperature analog output input to auto meter;
The CAN digital signal that in battery management system, SOC battery charge state exported originally exports, export a road artifical resistance amount on this basis, this battery change scope consistent with the variation range of the tank sensor of fuel-engined vehicle (tank sensor of fuel-engined vehicle is the change of slide rheostat, resistance value);
By instrument on fuel-engined vehicle tank sensor wire directly access the resistive mode analog quantity mouth of battery management system, the value of SOC is become analog output to analog output port by battery management system simultaneously, the fuel consumptio indicator in fuel-engined vehicle instrument just shows the pointer display of SOC;
The mean temperature of battery is passed through analog output, by battery draw temperature simulation amount mouth in the engine water temperature sensor port of fuel-engined vehicle instrument access battery management system, then the Engine Coolant Temperature table in traditional vehicle instrument just shows the pointer display of battery mean temperature;
According to the normal range of battery SOC and mean temperature, demarcate the transformation point of the analog output scope of battery SOC and draw temperature, make it consistent with the upper and lower critical value of resistance that fuel oil instrument and Engine Coolant Temperature statistical tables and reports are warned;
Utilize the logic in fuel-engined vehicle instrument, when the lower limit input of SOC time, light symbol sheet or the indicator lamp of " oil mass is low " in instrument; With surmounting normal engine temperature range by battery temperature, " temperature anomaly " symbol sheet or indicator lamp are lighted.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
