Description
技术领域 technical field
本实用新型属于汽车动力电池包热管理技术领域，尤其涉及一种太阳能补偿的电动车电池车载充电加热装置。 The utility model belongs to the technical field of thermal management of automobile power battery packs, in particular to a solar energy-compensated electric vehicle battery on-board charging and heating device.
背景技术 Background technique
随着作为不可再生能源的石油资源的日益枯竭，以及为了减轻燃油车对环境的污染，电动车辆已成为当前汽车工业研究的方向和开发的重点。电动车辆（纯电动汽车和混合动力汽车）最大的特点是使用动力电池对能量进行存储，并在车辆行驶过程中进行释放，因此动力电池是电动车辆上的一个关键零件。 With the depletion of petroleum resources as a non-renewable energy source, and in order to reduce the pollution of fuel vehicles to the environment, electric vehicles have become the current research direction and focus of development in the automotive industry. The biggest feature of electric vehicles (pure electric vehicles and hybrid vehicles) is the use of power batteries to store energy and release it during driving. Therefore, power batteries are a key part of electric vehicles.
目前，电动车辆上常用的动力电池有铅酸电池、镍镉电池、镍氢电池和锂离子电池等，由于二次环境污染，电池能量密度低等原因，铅酸电池、镍镉电池将逐步淡出市场，而电动车辆动力电池将以镍氢电池和锂离子电池为主。但是镍氢电池和锂离子电池在温度低于0℃时，充电的性能会大大幅度的降低，甚至发生过热、电解液溢出、爆裂等安全事故隐患。因此，在电动汽车或者混合动力汽车上，需要增加一个以加热为目的的热管理系统来对车辆动力电池包进行管理，使电池模块工作在最佳的温度区域内。 At present, the power batteries commonly used in electric vehicles include lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries. Due to secondary environmental pollution and low energy density of batteries, lead-acid batteries and nickel-cadmium batteries will gradually fade out. market, while electric vehicle power batteries will be dominated by nickel-metal hydride batteries and lithium-ion batteries. However, when the temperature of nickel-metal hydride batteries and lithium-ion batteries is lower than 0°C, the charging performance will be greatly reduced, and there may even be safety accidents such as overheating, electrolyte overflow, and bursting. Therefore, in an electric vehicle or a hybrid vehicle, it is necessary to add a thermal management system for heating purposes to manage the vehicle power battery pack, so that the battery module works in an optimal temperature range.
目前，动力电池包加热系统通常采用风热和水热两种结构形式，但是都存在一定的缺陷，风热装置在冬季低温环境下的加热效果有限，而完全使用空调风加热又会增加动力电池能量消耗，且电池包处于一个封闭状态，风热效果不能短时间内体现；水热装置结构复杂、成本高，而且一旦水热管路破裂，发生泄漏极易引起短路等问题，造成电池及其他设备的损坏，因此水热装置在当前电动汽车上采用较少。而且，不论是风热还是水热，一般都是通过电源直接供电加热，这也使得汽车的能耗加大。 At present, the power battery pack heating system usually adopts two structural forms: wind heat and water heat, but both have certain defects. The heating effect of the wind heat device is limited in the low temperature environment in winter, and the complete use of air-conditioning wind heating will increase the power of the power battery. Energy consumption, and the battery pack is in a closed state, the effect of wind heat cannot be reflected in a short time; the hydrothermal device has a complex structure and high cost, and once the hydrothermal pipe breaks, leakage will easily cause short circuits and other problems, causing battery and other equipment damage, so water heating devices are less used in current electric vehicles. Moreover, whether it is wind heat or water heat, it is generally heated by direct power supply, which also increases the energy consumption of the car.
