For a kind of walking-replacing tool the most universal in people's daily life.Storage battery is the power resources of electric car, at present storage battery
Mainly there are acid lead batteries, lithium battery and nickel-based battery etc., no matter for any storage battery, the remaining capacity of storage battery is all
It is related to the cruising ability of electric car.In order to facilitate bicyclist's safety, the in time remaining capacity of electrolytic cell, present electrokinetograph
There is the instruction to battery dump energy on dial plate, but simply segmentation roughly indicates battery condition, and as battery uses
The length of the time limit, the instruction of this electricity are also more and more inaccurate.
As technology makes constant progress, the display of electric car electricity is also more and more accurate, can only divide roughly from initial
Section shows electricity, finally can meticulously show the high pressure conditions of electricity, middle pressure condition, low-pressure state, under-voltage condition, to existing
It can show the percent value of battery capacity.But the display of battery capacity works as riding speed all there are common drawback now
When changing, electricity can also fluctuate back and forth, so can not accurately know remaining capacity；There is also peace in ride at the same time
Full hidden danger, because bicyclist's display watched on instrument board it is to be understood that remaining capacity must bow, without more humane language
Broadcasting system, passes through verbal cue remaining capacity.
Present electric car is only able to display electricity using electric quantity display system, it is impossible to is converted into riding by remaining capacity
Distance, user can not accurately know the also rideable distance of remaining capacity, and can only rule of thumb prejudge remaining capacity can ride
Capable mileage.With the increase of battery service life, aging, range error is ridden in experiential anticipation also can be increasing,
Often will in riding out of power, can not ride, very big worries are brought to user.So display to current battery charge
System needs to be further improved and enhanced

Discharge current, estimates SOC value of each single battery before and after discharge and recharge；S3, calculate each single battery after each discharge and recharge
SOH values；S4, judge that the SOH value in battery pack with the presence or absence of single battery is less than the first predetermined threshold value, if so then execute step
S6, conversely, performing step S5；S5, the average value for calculating the SOH value of all single batteries in battery pack, and judge in battery pack
With the presence or absence of SOH value and single battery of the average value more than the second predetermined threshold value, if so, then execution step S6, on the contrary
Return and perform step S1；S6, triggering battery management system enter guard mode and send alarm.This method is real-time, accurate
Degree is high, implementation is relatively simple and cost is low, can be widely applied in the monitoring field of battery pack, but this kind of method is not
To electric car, the remaining capacity of battery is detected and prompts in ride.
As Application No. 201710232206.0 disclose it is a kind of using possessing the electric vehicle battery charger system of warning function
The method for carrying out early warning, is included under constant pressure or constant current charging mode, and charger is exported by first resistor measuring instrument and is charged
Voltage, output charging current and battery input charging voltage are acquired, and battery is inputted by second resistance measuring instrument and is charged
Voltage, input charging current and charger output charging current are acquired；First resistor measuring instrument and second resistance measuring instrument
It is connected to a microcontroller；Microcontroller receives the signal value from first resistor measuring instrument and second resistance measuring instrument, leads to
The equivalent resistance that the gun joint (containing cable) that charges under constant pressure or constant current charging mode is calculated is crossed, and sends control signal pair
The service condition of charging gun carries out early warning.This method can monitor the conducting contact quality of charging circuit in real time, make new-energy automobile
When charging when long, can provide actively, in real time with accurate people, car, machine safeguard protection, but this kind of method do not provide how
The early warning and detection discharged.
