Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of process of the charge control method of electric car provided by the embodiment of the present invention Figure.This method may include:
Step 101: charge setting command based on the received, generates default cut-off carrying capacity.
It is understood that the purpose of this step can be the processor in electric car such as BMS (battery management system) By the charging setting command of user setting based on the received, default cut-off carrying capacity is generated, realizes user to power battery The adjusting of charge target electricity is arranged, i.e., user can be adjusted by the remaining capacity (state-of-charge, SOC) of setting charge cutoff Section power battery is filled with electricity, to meet the use demand of itself.
Specifically, in this step processor receive charging setting command concrete mode, i.e., user setting charge mesh The concrete mode for marking electricity (default cut-off carrying capacity), can be voluntarily to be set according to practical scene and user demand by designer It sets, as shown in Fig. 2, user can be arranged on the APP in the terminal of such as mobile phone and be connect by the cab signal in electric car It receives device and sends charging setting command to processor (BMS), is i.e. processor in electric car can receive (such as blue from being connected thereto Tooth connection or mobile network connection) terminal send charging setting command;User can also in electric car as vehicle-mounted Setting and charging setting command is sent to processor in the human-computer interaction device of DVD, i.e. processor in electric car can be with The charging setting command that the human-computer interaction device of its wired connection sends, as long as the charging that processor can receive user setting is set Order is set, the present embodiment does not do any restrictions to this.
It should be noted that the particular content of the charging setting command in this step, it can be by designer or user's root Scene and user demand self-setting are factually used, the setting command that such as charges can only include charge cutoff electricity (charge cutoff SOC), i.e., user can on the basis of original charging method (such as DC charging and AC charging method) direct self-setting Charge cutoff SOC;It can also only include charge mode selection instruction, i.e. user can lead on the basis of original charging method Selection charge mode is crossed, the corresponding charge cutoff SOC of charge mode of selection is set;It can also include charge mode selection instruction With corresponding charge cutoff electricity, such as electric car can root on the basis of the existing DC charging of compatibility and AC charging method Long-life mode and long both charge modes of mileage mode are selected according to user demand, default mode is long mileage mode, user Record charge mode can be chosen whether as needed.The difference of two kinds of charge modes can be the selection of charge cutoff SOC: long Life pattern charge cutoff SOC can be adjusted in a%~b%, using n% as minimum scale;Long mileage mode charge cutoff SOC can be It is adjusted between c%~d%, equally using n% as minimum scale.That is, user can choose long-life mode and long mileage mould Formula, and the numerical value in the corresponding default electricity range (a%~b% or c%~d%) of both charge modes.This reality It applies example and does not do any restrictions to this.
It is corresponding, it charges based on the received setting command for processor in this step, generates default cut-off carrying capacity Concrete mode, can be by designer's self-setting, and the setting command that such as charges includes charge mode selection instruction and corresponding fills Electricity cut-off electricity, and when charging strategy difference under the different charge mode of power battery, processor can not only set user As default cut-off carrying capacity, charge mode when can also be by power battery charging is set as user for the charge cutoff electricity set The charge mode of selection, i.e. this step may include receiving charging setting command;Wherein, charging setting command includes charge mode Selection instruction and corresponding charge cutoff electricity, charge cutoff state-of-charge are the corresponding default electricity of charge mode selection instruction Numerical value in range;Charge mode when power battery charging is set according to charge mode selection instruction, and charge cutoff is electric Amount is as default cut-off carrying capacity.The present embodiment does not do any restrictions to this.
Step 102: after power battery is charged, it is charged to judge whether the state-of-charge of power battery reaches default cut-off Amount;If so, entering step 103.
It is understood that the purpose of this step can be processor by the way that after power battery is charged, judgement is dynamic Whether the state-of-charge of power battery reaches default cut-off carrying capacity, it is determined whether the charging to power battery can be terminated, i.e., it is dynamic Whether the remaining capacity of power battery is to meet user demand.Specifically, the state-of-charge for judging power battery in this step Whether the specific time point setting of default cut-off carrying capacity is reached, it can be by designer's self-setting, such as when can preset Between interval acquiring power battery current state-of-charge, and judge whether state-of-charge reaches default cut-off carrying capacity, this reality It applies example and does not do any restrictions to this.
It is corresponding, for judging whether the state-of-charge of power battery reaches the specific of default cut-off carrying capacity in this step Mode such as can directly can judge whether the current state-of-charge of power battery reaches default by designer's self-setting End carrying capacity;It can also be as shown in figure 3, by judging the corresponding cell voltage (CVV) of the current state-of-charge of power battery Whether it is greater than or equal to the corresponding first voltage threshold value (CVV threshold value) of default cut-off carrying capacity, determines the current lotus of power battery Whether electricity condition reaches default cut-off carrying capacity, i.e., default cut-off carrying capacity not only can be generated in step 101, can also generate It is default to end the corresponding first voltage threshold value of carrying capacity.As long as this step may determine whether to terminate to fill power battery Electricity, the present embodiment do not do any restrictions to this.
Specifically, this step is by judging whether the corresponding cell voltage of the current state-of-charge of power battery is greater than or waits In the corresponding first voltage threshold value of default cut-off carrying capacity, determine whether the current state-of-charge of power battery reaches default cut-off Be not in that biggish fill less of departure is filled to guarantee to be filled with electricity as far as possible more when carrying capacity, need to require state-of-charge smart It is enough accurate that degree needs, and therefore, the strategy that the present embodiment can correct SOC by CCV guarantees the precision of SOC, that is, The cell voltage of battery determines that charging reaches the default cut-off of setting after reaching first voltage threshold value in the case where low current charge It can also include the steps that judging whether cell voltage is greater than or equal to second voltage threshold value before carrying capacity, i.e. this step;Its In, second voltage threshold value is less than first voltage threshold value;If so, the charging current of power battery is reduced to corresponding current threshold Value, is such as reduced to the corresponding current threshold of DC charging (such as 10A), the corresponding current threshold (example of AC charging for charging current Such as 5A), it enters back into this step and judges whether cell voltage is greater than or equal to the corresponding first voltage threshold value of default cut-off carrying capacity, To reduce the departure for being filled with electricity.
It should be noted that the case where being less than second voltage threshold value for above-mentioned cell voltage and state-of-charge do not reach The case where to default cut-off carrying capacity, it can directly terminate this process or be again introduced into corresponding judgment step, to obtain battery The state-of-charge of subsequent time during the charging process or corresponding cell voltage are judged that the present embodiment does not do this any Limitation.
Specifically, for the state-of-charge at the current time of acquisition power battery in this step and obtaining pre-set The concrete mode of default cut-off carrying capacity, can such as use side similar with the prior art by designer's self-setting Formula obtains the state-of-charge at the current time of power battery, and can be obtained using mode shown in Fig. 3 pre-set pre- If ending carrying capacity, that is, by judging whether to receive new charge cutoff electricity, determine whether user needs to be arranged newly Default cut-off carrying capacity;If so, it is default cut-off carrying capacity that new charge cutoff electricity, which is arranged, and CCV can used When correcting the precision of strategy guarantee SOC of SOC, corresponding end drop current strategy is set, that is, it is charged that new default cut-off is set Measure corresponding second voltage threshold value;If it is not, then can directly using the charge cutoff electricity that is arranged of user's last time of storage or Initial charge cutoff electricity is as default cut-off carrying capacity.The present embodiment does not do any restrictions to this.
Step 103: terminating the charging to power battery.
It is understood that the purpose of this step can be to carry out in charging process in power battery, the lotus of power battery When electricity condition reaches default cut-off carrying capacity, the charging to power battery is terminated by this step, makes the charged shape of power battery State (remaining capacity) can meet user demand, while a degree of can reduce full be full of and put to the power battery service life It influences, and carries out count by time sharing area in Beijing-Tianjin etc., night electricity price is relatively inexpensive, and user can setting according to charging setting command It sets to control the time that charging terminates, to avoid high price time interval, saves use cost.
It should be noted that the present embodiment is to utilize default cut-off carrying capacity sentencing after power battery is charged It is disconnected, the displaying carried out for the charging end time is determined, for utilizing default cut-off carrying capacity in electric car and external charge Judgement before equipment (such as charging pile) connects and power battery is charged, it is determined whether using external charge equipment to power electric The concrete mode that pond is charged can be configured using mode similar with the present embodiment is corresponding, such as set with external charge After standby connection, judge whether the state-of-charge of power battery reaches default cut-off carrying capacity;If it is not, then utilizing external charge equipment It charges by charge mode to power battery, and enters step 102;If so, can directly terminate process or return to judgement Whether the state-of-charge of power battery reaches the step of default cut-off carrying capacity, with obtain power battery subsequent time it is charged State, and judge whether to reach default cut-off carrying capacity, the present embodiment does not do any restrictions to this.
In the present embodiment, the embodiment of the present invention generates default cut-off carrying capacity by the setting command that charges based on the received, Corresponding default cut-off carrying capacity can be generated according to user demand, so that adjustable, the energy that is filled with electricity when power battery charging Enough meet the different use demands of different user, the user experience is improved;And it can make power battery that need not charge every time It is charged to full power state, the full influence for being full of and putting to the power battery service life is reduced, improves the power battery service life.
