Remainder Range of Electric Vehicle digital display of the present utility model shows that system can accurately detect and show the remaining mileage number that electronlmobil can be exercised, thereby can provide the information of exercising accurately for the battery-driven car driver, avoid causing because of remaining mileage is inaccurate unnecessary cast anchor midway, situation such as traffic jam.The utility model is simple in structure, with low cost, widely applicable, goes for various electronlmobils, and for example electric bus, electrocar etc. are suitable for popularization and application.
Description of drawings
Fig. 1 shows the structural representation of system for the utility model Remainder Range of Electric Vehicle digital display.
The specific embodiment
Describe Remainder Range of Electric Vehicle digital display of the present utility model below in conjunction with accompanying drawing and show system.
Referring to shown in Figure 1, described Remainder Range of Electric Vehicle digital display shows that system comprises battery management module, total power consumption modular converter, vehicle speed measurement module, mileage number modular converter and display module.Total electric weight that battery management module provides current battery to emit; The total power consumption modular converter provides the present described electronlmobil car required total electric weight of operational outfit; The vehicle speed measurement module detects the speed of a motor vehicle of current described electronlmobil; But total electric weight that the mileage number modular converter can be emitted current battery and present described the electronlmobil required total electric weight of operational outfit are divided by and draw discharge time, the current vehicle speed that being multiplied by the vehicle speed measurement module again provides calculates the remaining mileage number, is resent to display module at last.
Describe each composition module that the utility model Remainder Range of Electric Vehicle digital display shows system in detail below in conjunction with accompanying drawing.
The first, battery management module
Total electric weight that described battery management module provides the battery of present electronlmobil to emit, for accurate relatively total electric weight is provided, battery management module need be considered factors such as battery charging and discharging cycle, battery temperature.
Generally speaking, the battery charging and discharging cycle is meant that when charging electric weight adds up, when charge volume whenever reaches 0.8C for once discharging and recharging all numbers, during not enough 0.8C in the first storage system, with next charge capacity addition.If the total electric weight of battery is 1C, when one group of new battery pack was used for the first time, this moment, system thought that discharging and recharging cycle life is 0, and later every charging reaches certain electric weight (being 0.8C) and just can be regarded as increase and once discharge and recharge cycle life.Lithium cell can reach 2000 times in the cycle of discharging and recharging in theory.But actual use reaches 500 times and discharges and recharges more than the cycle, and capacity of cell will begin to descend.According to observed data, draw the loading capacity coefficient that discharges and recharges under the cycle influence:
N=1 (t＜500 o'clock) can emit electric total volume=rated capacity
N=0.95 (500＜t＜1000) can emit electric total volume=0.95 times rated capacity
N=0.9 (t＞1000) can emit electric total volume=0.9 times rated capacity
(wherein, N is the loading capacity coefficient that discharges and recharges under the cycle influence, and t is for discharging and recharging cycle life)
In addition, used battery mostly is ferric phosphate lithium cell on the present electronlmobil.Lithium cell is that organic electrolyte is done battery acid, and it is better that its capacity is brought into play about 25 degree, and temperature surpasses 35 degree, and capacity begins to descend, and is lower than 15 and spends, and capacity also descends bigger, and temperature is got back to room temperature, and capacity can recover again.
Capacity of cell formula: C

Battery management module once sampling each second battery charging voltage and electric current during charging, accumulation calculating is charge volume.When charging finishes, discharged and recharged cycle life according to battery and be converted to total capacity of cell and leave in the battery management module.Per second once sampling cell pressure and discharge current when automobile is set out on a journey, and calculate total electric weight that battery can be emitted in real time according to battery temperature.The battery management module total amount of finally can discharging is passed to remaining mileage number conversion module.
The second, the total power consumption modular converter
Total power consumption modular converter: this module per second once sampling, confirm existing normal operational outfit on the electronlmobil, and the power consumption that moves each equipment is carried out phase waited until the present described electronlmobil car required total electric weight of operational outfit, transfer to remaining mileage number conversion module.
The 3rd, the vehicle speed measurement module
Vehicle speed measurement module: measure the actual current real-world operation speed of bus by change speed gear box tachogen or wheel speed sensor.
The 4th, remaining mileage number conversion module
Remaining mileage number conversion module: according to three module datas (battery management module, total power consumption modular converter, vehicle speed measurement module), per second calculates once by following formula
Remaining mileage number=(the electric total amount/described electronlmobil that can emit of current battery is the required total electric weight of operational outfit) * current vehicle speed.
At last the remaining mileage number that can exercise, total power consumption, the speed of a motor vehicle, remaining mileage number are delivered to display module.
The 5th, display module
Display module: per second upgrades a secondary data, shows that in real time above-mentioned data are for driver's reference.If the driver finds the remaining mileage number more after a little while, can close accessory equipments such as air-conditioning, this moment, total power consumption will reduce, and corresponding remaining mileage number will increase.The accuracy and the real-time of system's demonstration improve greatly like this.
Remainder Range of Electric Vehicle digital display of the present utility model shows that system can accurately detect and show the remaining mileage number that electronlmobil can be exercised, thereby can provide the information of exercising accurately for the battery-driven car driver, avoid causing because of remaining mileage is inaccurate unnecessary cast anchor midway, situation such as traffic jam.The utility model is simple in structure, with low cost, widely applicable, goes for various electronlmobils, and for example electric bus, electrocar etc. are suitable for popularization and application.
Each concrete technical characterictic described in the above-mentioned specific embodiment can carry out combination in any by any suitable manner, and it falls within the scope disclosed in the utility model equally.In addition, also can carry out combination in any between the various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.Below describe preferred implementation of the present utility model in conjunction with the accompanying drawings in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.Protection domain of the present utility model is defined by the claims.
