Specific embodiment
What is be described below is some in multiple embodiments of the utility model, it is desirable to provide to the basic of the utility model
Understand.It is not intended to the crucial or conclusive element of confirmation the utility model or limits scope of the claimed.
Fig. 1 is the organigram of the vehicle A-battery management system of the utility model.
As shown in Figure 1, A-battery 100 and DCDC200 provide electric energy, the vehicle of the utility model to low-voltage load 300
A-battery management system is for being controlled such that it is in due course so that DCDC200 is to low pressure to DCDC200
Battery 100 charges.
The vehicle A-battery management system of the utility model system has:
DCDC200, for the power battery of vehicle is converted into low pressure and be used to charge to A-battery 100 with
And vehicle is powered；
Battery detection module 400, for acquiring the battery status information of A-battery 100 in real time；And
Low voltage energy management module 500, for being controlled whether according to the battery status information from battery detection module 400
DCDC200 is waken up to charge to A-battery 100.
Wherein, communication bus (LIN can for example be passed through between battery detection module 400 and low voltage energy management module 500
Bus) carry out information transmission.As an embodiment, the battery detection module 400, which can be, to be arranged in the low tension
The sensor of the negative terminal in pond 100.
As shown in Figure 1, A-battery 100 and DCDC200 can power to vehicle-mounted low-voltage load 300, in Fig. 1
The case where DCDC200 is powered low-voltage load 300 is equivalent to the case where " being powered to vehicle " among the above.
Battery detection module 400 has following one or mores (not shown):
For acquiring the state-of-charge acquisition module of the state-of-charge (i.e. SOC) of A-battery 100；
For acquiring the battery health degree acquisition module of the battery health degree (i.e. SOH) of A-battery 100；

Fig. 2 is that the construction of the low voltage energy management module 300 in the vehicle A-battery management system of the utility model shows
It is intended to.
As shown in Fig. 2, low voltage energy management module 500 has:
Information receiving submodule 510, for receiving battery status information from battery detection module 400；And
Whether control submodule 520, the battery status information for being received based on information receiving submodule 510 are waken up
DCDC200 is charge and/or be powered vehicle to A-battery 100.
Control submodule 520 is set as waking up vehicle in the case where meeting following any one or several
DCDC200 is so that DCDC200 charges to A-battery 100:
If the state-of-charge for the A-battery 100 that vehicle is detected when battery detection module 400 in a sleep state is lower than
Preset state-of-charge threshold value；

Voltage threshold；And
If the battery health degree for the A-battery 100 that vehicle is detected when battery detection module 400 in a sleep state is low
In preset health degree threshold value.
Wherein, it in the case that the discharge current of the A-battery 100 detected is greater than preset threshold, is further arranged to
Except control submodule setting 520 to wake up DCDC200 to charge to A-battery 100, and also wake up
DCDC200 is powered vehicle.
When the battery detection module 400 breaks down, by the control submodule 520 according to local power supply voltage
Threshold value (i.e. the supply voltage threshold value of low voltage energy management module 500 itself) judge whether wake up DCDC to A-battery 100 into
Row charging is detected without basis by current detection module 400 to be carried out judging whether to wake up lower than above-mentioned preset voltage threshold
DCDC charges to A-battery 100.That is, optionally leading to when battery detection module 400 breaks down
The local power supply voltage threshold decision of too low pressure energy management module 500 or other modules charges to wake up control module, usually
The voltage threshold should be lower than the preset voltage threshold of battery detection module 400, and thereby, it is possible to prevent battery detection module 400
The feed of vehicle caused by failure problems is not available.
Further, wherein as an implementation, control submodule 520 has: threshold value wake-up module, for being arranged
Above-mentioned each threshold value and according to whether reach threshold value to determine whether waking up DCDC200 and can change in real time preset
Each threshold value.
As a kind of preferred mode of the utility model, above-mentioned threshold value wake-up module can be not arranged in control submodule
It in block 520, but replaces, is arranged in current detection module 400.Such preferred embodiment is carried out briefly below
It is bright.
Under this preferred embodiment, threshold value wake-up module is set in 400 side of current detection module, wherein the threshold value wakes up mould
Block is used to be arranged the above-mentioned each threshold value judged and according to whether reaches threshold value to wake up control submodule setting 520 and be
It is no to carry out above-mentioned judgement and preset each threshold value be changed in real time in threshold value wake-up module.
In this case, since threshold value wake-up module is arranged in current detection module 400, it is slept in vehicle
Judgement can be carried out to each threshold value in advance under sleep mode and only just wake up control submodule in the event that the threshold is reached
The 520 subsequent secondary judgements (judgement of above-mentioned each threshold value) of progress are set.
The effect being arranged in this way is, due to being arranged in current detection module 400, does not need to be arranged with control submodule
520 interaction can carry out threshold decision in advance, vehicle can be allowed still to be in sleep state, therefore can save electricity consumption.
As described above, vehicle A-battery management system according to the present utility model, can capture in time for low pressure
The opportunity that battery charges effectively can carry out energy supplement to A-battery, also can prevent A-battery depth from putting
Influence of the electricity for the A-battery service life, to improve car experience and complete vehicle quality.
Example above primarily illustrates the vehicle A-battery management system of the utility model of the utility model.Although only
Some of specific embodiment of the present utility model are described, but those of ordinary skill in the art it is to be appreciated that
The utility model can implemented without departing from its spirit in range in many other form.Therefore, the example that is shown with
Embodiment is considered as illustrative and not restrictive, is not departing from the utility model as defined in appended claims
