背景技术Background technique
混合动力汽车一般由一个内燃机结合一个或多个电池和电机来形成混合动力驱动系统。内燃机消耗燃料，将燃料的化学能转换成动能和热能，动能用于驱动车辆行驶，热能往往以废气等形式耗散至周围环境。电池负责向电机供电，将电能转化为动能驱动车辆行驶。电池的性能会受到温度的影响，当电池的周围环境温度或者电池温度低于预定温度值，如-8℃，电池的性能会显著下降，从而影响混动动力系统的性能，如：能量回收、起/停功能。当车辆处于纯电动状态时，蓄电池温度以及电荷状态的降低还会对整车动力性造成影响。为了提升电池性能，一些插电式混合动力系统可以让车辆接入外接充电装置充电，同时利用电阻型加热器加热电池，然而在许多地方如车站、机场或者商业停车场，往往没有外接充电装置，而且目前绝大部分的混合动力系统不具备外界充电功能。此外，还有一些驾驶员会通过让发动机怠速空转来让车辆其他部件升温，但对于电池尤其是锂电池而言，其温度往往不会随着发动机的运行而增加。因此如果能够利用车辆本身的热能来确保电池温度和电荷状态始终处于理想状态，将对混合动力汽车整车性能的提高具有十分重要的意义。A hybrid electric vehicle generally consists of an internal combustion engine combined with one or more batteries and electric motors to form a hybrid drive system. The internal combustion engine consumes fuel and converts the chemical energy of the fuel into kinetic energy and heat energy. The kinetic energy is used to drive the vehicle, and the heat energy is often dissipated to the surrounding environment in the form of exhaust gas. The battery is responsible for supplying power to the motor, which converts electrical energy into kinetic energy to drive the vehicle. The performance of the battery will be affected by the temperature. When the ambient temperature of the battery or the temperature of the battery is lower than a predetermined temperature value, such as -8°C, the performance of the battery will drop significantly, thereby affecting the performance of the hybrid power system, such as: energy recovery, Start/stop function. When the vehicle is in a purely electric state, the decrease in battery temperature and state of charge will also affect the power of the vehicle. In order to improve battery performance, some plug-in hybrid systems allow the vehicle to be connected to an external charging device for charging, and at the same time use a resistance heater to heat the battery. However, in many places such as stations, airports or commercial parking lots, there are often no external charging devices. Moreover, the vast majority of hybrid power systems do not have an external charging function. In addition, some drivers will let other parts of the vehicle heat up by idling the engine, but for batteries, especially lithium batteries, their temperature often does not increase with the operation of the engine. Therefore, if the thermal energy of the vehicle itself can be used to ensure that the battery temperature and state of charge are always in an ideal state, it will be of great significance to improve the performance of the hybrid vehicle.

本发明在车辆排气系统上增设废气热量回收装置，将废气中的热能通过热能传递回路转移至第一热交换器和第二热交换器，第一热交换器可以利用热能给电池加热，第二热交换器可以和热电装置配合利用热能给电池充电，从而实现利用车辆排放出的废气中的热能给电池加热和/或充电。In the present invention, an exhaust gas heat recovery device is added to the exhaust system of the vehicle, and the heat energy in the exhaust gas is transferred to the first heat exchanger and the second heat exchanger through the heat energy transfer circuit. The first heat exchanger can use heat energy to heat the battery. The second heat exchanger can cooperate with the thermoelectric device to use heat energy to charge the battery, so that the heat energy in the exhaust gas emitted by the vehicle can be used to heat and/or charge the battery.
通过安装在电池上的温度传感器和电荷状态指示器实时监测电池的温度和电荷状态，控制器根据电池的温度和电荷状态、以及根据电池的具体参数确定的最低温度预定值、最高温度预设值和电荷状态预定值，通过对第一分流阀和第二分流阀的控制，来控制所述混合动力汽车电池加热和充电装置的运行，确定是否给电池加热或者充电。The temperature and charge state of the battery are monitored in real time through the temperature sensor and charge state indicator installed on the battery.

只要电池温度低于最高温度预设值或者电荷状态低于电荷状态预定值时，废气热量回收装置就处于工作状态，回收废气中的热能，否则，废气热量回收装置不工作，废气直接导入排气管排至车外。当电池温度低于最低温度预定值时，此时无论电池电荷状态如何，所有热能全部用于给电池加热，因为温度低时，电池的性能会很差，即使充电，效率也很低；当电池温度处于最低温度预定值和最高温度预设值之间时，若电荷状态高于电荷状态预定值，则热能全部用于给电池加热，若电荷状态低于电荷状态预定值，则热能一部分用于给电池加热，另一部分用于给电池充电；当电池温度达到最高温度预设值时，此时停止给电池加热，热能全部用于给电池充电。As long as the battery temperature is lower than the maximum temperature preset value or the state of charge is lower than the predetermined value of the charge state, the exhaust gas heat recovery device is in the working state to recover the heat energy in the exhaust gas, otherwise, the exhaust gas heat recovery device does not work, and the exhaust gas is directly introduced into the exhaust gas pipe to the outside of the vehicle. When the battery temperature is lower than the minimum temperature preset value, all heat energy is used to heat the battery regardless of the battery charge state at this time, because when the temperature is low, the performance of the battery will be very poor, even if it is charged, the efficiency is very low; when the battery When the temperature is between the minimum temperature preset value and the maximum temperature preset value, if the state of charge is higher than the predetermined value of the state of charge, all the heat energy is used to heat the battery; if the state of charge is lower than the predetermined value of the state of charge, part of the heat energy is used for Heat the battery, and the other part is used to charge the battery; when the battery temperature reaches the maximum temperature preset value, stop heating the battery at this time, and all the heat energy is used to charge the battery.

具体的，本发明所述混合动力汽车电池加热和充电装置的控制方法为：Specifically, the control method of the hybrid electric vehicle battery heating and charging device of the present invention is as follows:
首先，温度传感器180和电荷状态指示器190实时监测电池170的温度和电荷状态，并将电池170的实时温度和电荷状态信号传输到控制器210。Firstly, the temperature sensor 180 and the state-of-charge indicator 190 monitor the temperature and state-of-charge of the battery 170 in real time, and transmit the real-time temperature and state-of-charge signals of the battery 170 to the controller 210 .
然后，控制器210根据电池170的实时温度、电荷状态信号分别与电池170的最高温度预设值、电荷状态预设值进行比较，当电池170的实时温度低于最高温度预设值或者电荷状态低于电荷状态预定值时，控制器210控制第一分流阀114将废气分流至分支气管117，废气热交换器118将废气中的热量转移至传热流体中；否则，控制器210控制第一分流阀114将废气直接导入排气管116排至车外。Then, the controller 210 compares the real-time temperature and charge state signal of the battery 170 with the maximum temperature preset value and the charge state preset value of the battery 170 respectively. When the real-time temperature of the battery 170 is lower than the maximum temperature preset value or the charge state When the charge state is lower than the predetermined value, the controller 210 controls the first diverter valve 114 to divert the exhaust gas to the branch air pipe 117, and the exhaust gas heat exchanger 118 transfers the heat in the exhaust gas to the heat transfer fluid; otherwise, the controller 210 controls the first The diverter valve 114 guides the exhaust gas directly into the exhaust pipe 116 to be discharged out of the vehicle.
最后，控制器210进一步判断电池170的实时温度是否低于电池170的最低温度预定值，若是，控制器210控制第二分流阀126仅导通第一管路121与第一热交换器130，如图3所示，传热流体中的热能仅用于加热电池盖板160，为电池170加热，使电池170升温，温度保持正常；若不是，则控制器210进一步判断电池170的实时温度是否介于电池170的最低温度预定值与最高温度预设值之间。当电池170的实时温度不介于电池170的最低温度预定值与最高温度预设值之间时，控制器210控制第二分流阀126仅导通第一管路121与第二热交换器140，如图5所示，第二热交换器140将流经的传热流体中的热能转移至热电装置145，热电装置145吸收热能利用温差产生电能，电能以电流的形式通过导线150输入电池170，对电池170充电，使电荷状态保持正常；当电池170的实时温度介于电池170的最低温度预定值与最高温度预设值之间时，则控制器210进一步判断电池170的实时电池170电荷状态是否大于电荷状态预设值。若电池170的实时电池170电荷状态大于电荷状态预设值，控制器210控制第二分流阀126仅导通第一管路121与第一热交换器130，如图3所示，传热流体中的热能仅用于加热电池盖板160，为电池170加热；若电池170的实时电池电荷状态不大于电荷状态预设值，控制器210控制第二分流阀126同时导通第一管路121与第一热交换器130、第二热交换器140，如图5所示，传热流体中的热能同时用于电池170加热、充电，使电池170的温度和电荷状态最终达到正常水平。Finally, the controller 210 further judges whether the real-time temperature of the battery 170 is lower than the preset minimum temperature of the battery 170, and if so, the controller 210 controls the second diverter valve 126 to connect only the first pipeline 121 and the first heat exchanger 130, As shown in Figure 3, the thermal energy in the heat transfer fluid is only used to heat the battery cover plate 160 to heat the battery 170 to heat up the battery 170 and keep the temperature normal; if not, the controller 210 further judges whether the real-time temperature of the battery 170 is It is between the minimum temperature preset value and the maximum temperature preset value of the battery 170 . When the real-time temperature of the battery 170 is not between the minimum temperature preset value and the maximum temperature preset value of the battery 170, the controller 210 controls the second diverter valve 126 to only connect the first pipeline 121 and the second heat exchanger 140 , as shown in FIG. 5 , the second heat exchanger 140 transfers the heat energy in the passing heat transfer fluid to the thermoelectric device 145, and the thermoelectric device 145 absorbs the heat energy and utilizes the temperature difference to generate electric energy, and the electric energy is input into the battery 170 through the wire 150 in the form of electric current , charge the battery 170 to keep the state of charge normal; when the real-time temperature of the battery 170 is between the minimum temperature preset value and the maximum temperature preset value of the battery 170, the controller 210 further judges the real-time battery 170 charge of the battery 170 Whether the state is greater than the charge state preset value. If the real-time state of charge of the battery 170 of the battery 170 is greater than the preset value of the state of charge, the controller 210 controls the second diverter valve 126 to connect only the first pipeline 121 and the first heat exchanger 130, as shown in FIG. 3 , the heat transfer fluid The heat energy in the battery is only used to heat the battery cover 160 to heat the battery 170; if the real-time battery charge state of the battery 170 is not greater than the charge state preset value, the controller 210 controls the second shunt valve 126 and conducts the first pipeline 121 at the same time Together with the first heat exchanger 130 and the second heat exchanger 140 , as shown in FIG. 5 , the thermal energy in the heat transfer fluid is used for heating and charging the battery 170 at the same time, so that the temperature and charge state of the battery 170 finally reach normal levels.
