下面以电动汽车为例，通过一个实施例对本申请实施例提供的充电方法进行说明。Taking an electric vehicle as an example below, the charging method provided by the embodiment of the present application will be described through an embodiment.
因电池在低温环境下，性能受限，无法进行大电流充放电，故电动汽车存在冬季充电时间长的问题。Because the performance of the battery is limited in the low temperature environment, it cannot be charged and discharged with a large current, so the electric vehicle has the problem of a long charging time in winter.
相关技术在低温环境下充电方案为：先通过电池小电流放电，给PTC热敏元件加热，通过PTC元件再给冷却液加热，逐步提高冷却液的温度，通过冷却液再给电池加热，待电池温度达到较高温度后再开始大电流充电。The charging scheme of the related technology in a low temperature environment is: first discharge the battery with a small current, heat the PTC thermal element, then heat the cooling liquid through the PTC element, gradually increase the temperature of the cooling liquid, and then heat the battery through the cooling liquid. After the temperature reaches a higher temperature, high current charging starts.
可以看出：上述充电过程中，电池温升时间长，充电等待时间长、充电总时间长。It can be seen that in the above charging process, the battery temperature rise time is long, the charging waiting time is long, and the total charging time is long.
本申请的该实施例对于用户希望缩短充电时间的需求，提出低温环境下采用脉冲大电流充电，以达到缩短低温充电时间的目的，电池温度也快速抬升至适宜的工作的温度，转为正常的大电流直流充电。This embodiment of the present application proposes to use pulsed high current charging in a low temperature environment to shorten the low temperature charging time for the needs of users who want to shorten the charging time. High current DC charging.
下面对该实施例的方案进行具体说明。The solution of this embodiment will be specifically described below.
电池在大倍率直流充电时，电芯负极因无法快速完成嵌锂，造成负极过极化从而析锂，造成电池容量衰减，寿命降低。但在高频交流脉冲下，电芯负极发生充电嵌锂后，瞬间又随即放电脱锂。这样，电池可承受的电流幅值(也可以称为电流倍率或者简称为倍率)随频率的增加而增大。When the battery is charged with high-rate DC, the negative electrode of the battery cell cannot quickly complete the insertion of lithium, causing the negative electrode to be overpolarized and lithium-deposited, resulting in battery capacity degradation and reduced life. However, under the high-frequency AC pulse, after the negative electrode of the cell is charged and intercalated, it is immediately discharged and delithiated. In this way, the current amplitude (which may also be referred to as current rate or simply rate) that the battery can withstand increases as the frequency increases.
图7示意了一种不同温度下电池可承受的电流幅值与频率之间的关系。Figure 7 illustrates the relationship between the current amplitude and frequency that a battery can withstand at different temperatures.
从图7中可以看到：在高温、中温以及低温环境下，电池可承受的电流幅值(倍率)均随着频率的增加(从低频到中频再到高频)而增大；且在低温环境下，该变化更加明显。As can be seen from Figure 7: in high temperature, medium temperature and low temperature environments, the current amplitude (rate) that the battery can withstand increases with the increase of frequency (from low frequency to medium frequency to high frequency); and at low temperature In the environment, the change is more obvious.
基于此，本申请的该实施例提出一种可缩短低温环境下充电的方法。具体的原理可以包括：依据Q＝It，其中，Q表示电量；I表示电流；t表示充电时间。在一个充电周期S内，在t1时间内，采用R大倍率瞬时充电，静置t2时间后，再进入下一个充电周期，从而使一个S周期内，通过瞬时通电方式(也可以成为脉冲充电方式)得到的容量值Q1，大于在t1+t2时间内以小电流充电方式充入的电量Q2。Based on this, this embodiment of the present application proposes a method that can shorten charging in a low temperature environment. The specific principle may include: according to Q=It, wherein Q represents the electric quantity; I represents the current; t represents the charging time. In one charging cycle S, within t1 time, use R high rate of instantaneous charging, and after standing for t2 time, then enter the next charging cycle, so that in one S cycle, through the instantaneous power-on method (which can also become a pulse charging method ) The obtained capacity value Q1 is greater than the amount of electricity Q2 charged by the small current charging method within the time t1+t2.
这样，瞬时通电方式在单位时间内充入电池内电量较多，较常规直流充电方式，总时间便减少，用户等待时间缩短。In this way, the instantaneous power-on method charges more power into the battery per unit time, which reduces the total time and the waiting time of the user compared with the conventional DC charging method.
脉冲电流只取充电电流，电芯内部仍需一定的静置时间，完成锂离子的内嵌，找到合适的充电与静置时间比值，与充电倍率结合即可求得最短充电时间。The pulse current only takes the charging current, and a certain resting time is still required inside the battery cell to complete the embedding of lithium ions. Find the appropriate ratio of charging and resting time, and combine with the charging rate to obtain the shortest charging time.
具体可以包括但不限于下述步骤一至步骤三。Specifically, it may include but not limited to the following
步骤一、通过电芯标定方式，获得不同温度、不同频率下，电芯内部可充分反应的充电与脉冲周期的比值k(相当于充电时间比)。Step 1: Obtain the ratio k (equivalent to the charging time ratio) of the charging to the pulse period that can be fully reacted inside the battery under different temperatures and different frequencies by means of cell calibration.
其中，k的取值可以通过下述公式(1)来描述。The value of k can be described by the following formula (1).
k＝t1/(t1+t2) 公式(1)；k=t1/(t1+t2) Formula (1);
在公式(1)中，t1表示充电时间，t2表示静置时间。In formula (1), t1 represents the charging time, and t2 represents the resting time.
由公式(1)可以看出，获得不同温度下的k值，即获得对应的t1和t2。It can be seen from formula (1) that obtaining k values at different temperatures means obtaining corresponding t1 and t2.
先测定某特定温度下的，不同周期t1+t2条件下与对应的安全脉冲充电倍率R，从中取R×t1/(t1+t2)的最大值，作为该温度点下最佳参数。First measure the corresponding safe pulse charging rate R under the conditions of different periods t1+t2 at a certain temperature, and take the maximum value of R×t1/(t1+t2) as the optimal parameter at this temperature point.
例如，在-20℃环境下，不同充电周期t1+t2条件下与对应的安全脉冲充电倍率R可以如下述表2所示。For example, in the environment of -20°C, the corresponding safe pulse charging rate R under the conditions of different charging cycles t1+t2 can be shown in Table 2 below.
表2-20℃环境下不同充电周期对应的充电倍率示例Table 2-Example of charging rate corresponding to different charging cycles under 20℃ environment
然后，再测定多个温度点下的R×t1/(t1+t2)的最佳值，形成MAP表(相当于参数信息)。Then, the optimum value of R×t1/(t1+t2) at a plurality of temperature points is measured to form a MAP table (corresponding to parameter information).
表3MAP表示例Table 3 MAP table example
步骤二、电池充电增加脉冲充电模式，将步骤一中数据形成MAP表，嵌入至电池电池管理系统(Battery Management System，BMS)软件算法中，并设定当电池温度低于温度阈值X时，进入脉冲充电模式。Step 2: Increase the pulse charging mode for battery charging, form a MAP table with the data in
步骤三、采用特种充电桩，进行充电。Step 3: Use special charging piles for charging.
该充电桩相较于常规充电桩新增有脉冲充电模式，脉冲充电模式下，通过脉冲电流(Pulse current，PC)进行充电。当检测到与电池充电连接正常后，通过控制器局域网络(Controller Area Network，CAN)总线进行温度判断，判断首先进入何种充电模式。Compared with the conventional charging pile, the charging pile has a new pulse charging mode. In the pulse charging mode, the charging is performed by a pulse current (Pulse current, PC). When it is detected that the connection with the battery charging is normal, the temperature is judged through a controller area network (Controller Area Network, CAN) bus to judge which charging mode to enter first.
如图8所示，特种充电桩80包括直流充电模块801(Direct Current，DC)、脉冲充电模块802(Pulse Current，PC)、充电桩控制器803以及电动汽车的电池804。As shown in FIG. 8 , the special charging pile 80 includes a DC charging module 801 (Direct Current, DC), a pulse charging module 802 (Pulse Current, PC), a charging pile controller 803 and a battery 804 of an electric vehicle.

充电桩控制器803的一端与直流充电模块801和脉冲充电模块802连接，另一端与电动汽车的电池804连接。充电桩控制器803用于通过CAN总线进行温度判断，并基于判断结果控制直流充电模块801或者脉冲充电模块802对电动汽车的电池804充电。One end of the charging pile controller 803 is connected to the DC charging module 801 and the pulse charging module 802, and the other end is connected to the battery 804 of the electric vehicle. The charging pile controller 803 is used to judge the temperature through the CAN bus, and control the DC charging module 801 or the pulse charging module 802 to charge the battery 804 of the electric vehicle based on the judgment result.
下面，对充电过程进行描述。如图9所示，该过程可以包括但不限于下述S901至S905。Next, the charging process will be described. As shown in FIG. 9 , the process may include, but is not limited to, the following S901 to S905.
S901、电池充电连接正常。S901, the battery charging connection is normal.
S902、检测电池温度是否大于第一温度阈值。S902. Detect whether the battery temperature is greater than a first temperature threshold.
若电池温度大于第一温度阈值，则执行下述S903；若电池温度不大于第一温度阈值，则执行下述S904。If the battery temperature is greater than the first temperature threshold, execute the following S903; if the battery temperature is not greater than the first temperature threshold, execute the following S904.
S903、采用直流充电模式充电。S903, use DC charging mode to charge.
S904、采用脉冲充电模式充电。S904, charging in a pulse charging mode.
S905、查表获取当前最佳脉冲充电系数，输出脉冲电流。S905, look up the table to obtain the current optimal pulse charging coefficient, and output the pulse current.
需要说明的是，在第一预设时间后，重新执行S902。It should be noted that, after the first preset time, S902 is re-executed.
在低温充电场景下，当电池温度低于温度阈值X值时，查表可得当前温度条件下R×t1/(t1+t2)的最大值，并将该最大值对应的参数作为当前脉冲充电的最佳系数，以此展开脉冲充电。In the low temperature charging scenario, when the battery temperature is lower than the temperature threshold X value, the maximum value of R×t1/(t1+t2) under the current temperature condition can be obtained by looking up the table, and the parameter corresponding to the maximum value is used as the current pulse charging The optimal coefficient of , to expand the pulse charging.
在一定的低温环境下，采用R倍率电流幅值，单位充电时间t＝t1/(t1+t2),若R×t1/(t1+t2)＞1，则单位时间内充入电量较常规直流t时间充入的电量大，低温充电阶段耗时T’比常规充电方式用时T时间明显缩短。这样，一方面可让电池电量充入较多，另一方面，因电流增大，产热也增大，快速提高温度达到较适宜的工温度，可转为直流大电流充电，总充电时间缩短。In a certain low temperature environment, the R rate current amplitude is used, and the unit charging time t=t1/(t1+t2), if R×t1/(t1+t2)>1, the unit time charging capacity is more than conventional DC The amount of electricity charged at time t is large, and the time T' in the low-temperature charging stage is significantly shorter than that in the conventional charging method. In this way, on the one hand, the battery can be charged more, on the other hand, due to the increase of the current, the heat generation also increases, and the temperature can be quickly increased to reach a more suitable working temperature, which can be converted to DC high current charging, and the total charging time is shortened. .
图10示意了一种常规直流充电与脉冲充电的对比图。FIG. 10 illustrates a comparison diagram of conventional DC charging and pulsed charging.
其中，图10中虚线表示电流值，R-C表示采用脉冲充电方式充电，t1表示充电时间t2表示静置时间，T’表示脉冲充电方式下的充电总耗时；常规直流充电方式总耗时T，可以看出，T’小于T，即脉冲充电较常规直流充电的耗时短。Among them, the dotted line in Figure 10 represents the current value, R-C represents the charging by the pulse charging method, t1 represents the charging time, t2 represents the resting time, and T' represents the total charging time under the pulse charging method; the conventional DC charging method takes T, It can be seen that T' is less than T, that is, pulse charging takes less time than conventional DC charging.
