On July 19, 2019, BYD Co., LTD. (hereinafter referred to as BYD) signed a contract with Toyota Motor Corporation (hereinafter referred to as Toyota) to jointly develop pure electric models for sedans and low-chassis SUVs, as well as the power batteries needed for these products. The model will be under the Toyota brand and is scheduled to be launched in China by 2025.

BYD (BuildYourDreams) started in the battery business in 1995, mastering battery, IGBT, motor, electric control and other core technologies of electric vehicles, has become able to provide electric vehicles and power batteries, including the whole solution of new energy enterprises. BYD launched the world's first mass-produced plug-in hybrid electric vehicle (PHEV) in 2008, and from 2015, achieved the world's first sales of new energy vehicles (PHEV and EV) for four consecutive years.

Since the launch of the world's first mass-produced hybrid model in 1997, Toyota has been a pioneer in the field of electric vehicle development, with rich technology and experience in R&D, manufacturing and sales.

Advantages of open source platform

In BNA design, there is a core revolutionary concept - "openness". The DiLink intelligent network system and D++ open ecology created by BYD is an open source vehicular intelligent development platform, which can provide open interface, vehicle data and control rights for developers.

BYD's open nature based on electric business platform and the collocation of the battery business, should be regarded as BYD thrown in 2019, a powerful combination, for byd platform opening to the outside world, can help byd in the areas of power batteries and electric drive, compared to the competitors have differentiated competitive advantage. For example, compared with CATL (72.500,1.00,1.40%), BYD can not only provide power batteries, but also provide overall EV infrastructure solutions.

For a big MAC type car companies such as Toyota, its biggest attraction is - in the first place in the Chinese domestic market, BYD signed can obtain a long-lasting battery supplier solutions, large car company high-speed expansion in the face of the future market, must be able to ensure the security of the core components - the supply of power battery, and BYD as one of the biggest options, It's certainly more attractive than the current, star-studded era of CATL, and given that it already has partnerships with multinational automakers, Toyota's ability to keep its proprietary technology ahead of the market by not putting all its eggs in one basket.

What is more important is that Toyota did not do electric cars at that time, but was disselling electric cars or talking about an early market. The market realized too early but failed to catch up with the launch of China's huge new energy consumption market, so it only adopted the compromise route of hybrid in the end of last century to the first 10 years of this century. Being able to partner with BYD, which has a global electric vehicle business in the same period as Tesla, and offering an open source platform, is an offer that no smart car company should turn down.

Toyota BYD teamed up with necessity

It is worth noting that the Ministry of Industry and Information Technology has made it clear on June 24 that it has abolished the proposed list of battery suppliers, that is, the list of eligible enterprises commonly known as the power battery whitelist. A number of foreign battery companies said the catalog liberalization could open the door to the world's largest EV battery market.

If seeing the subtext of the Chinese ministry of industry, it means that for the last 4 years or longer period of China's power (23.780, 0.12, 0.51%) battery support policy, along with a bunch of mainstream companies such as era of CATL, BYD, a firm foothold in the international market, will break the current pattern of "are" subsidies, to better founded in the pattern of foreign companies to compete.

BYD, which announced last year that it was freeing up its power battery supply, is closing in on CATL in market share. It has all the more reason to iterate on its core competencies during this period of "oligopolistic upheaval." Toyota's endorsement adds another significance: BYD will have to do a lot less "educating" other potential partners.

And to the reform of the Toyota President Akio Toyoda, electric products, if cannot obtain the cost competitiveness, it will be hard to compete with fuel vehicles effectively, he needs to persuade the Toyota system inside the old minister to complete such as mountain Toyota positive turn in the 21st century, and the best way to convince a bunch of old cars - for electric products, to get the cost competitiveness, Need to reduce the allocation of research and development, reduce the allocation of fixed assets (manufacturing costs) and reduce procurement costs.

At this level, scale becomes extremely critical. This is why in the Japanese market, Toyota will jointly suzuki, Mazda, subaru, daihatsu and hino, common reasons of developing electric vehicle infrastructure platform, and in the Chinese market, in addition to the era of CATL, one of the largest local power battery shipments and most manufacturing experience of BYD is the main object, Toyota should choose strategic cooperation This is why continuous Mercedes insist and BYD cooperation for many years, even in the trend of "rise" project appear temporarily difficult circumstances is still one of the reasons for leave, because, give up means nothing, and stay in touch even in the possible space to carry out strategic cooperation, can yet be regarded as the current traditional car companies in car four modernizations more bets in the strategic transformation is in order.

The two sides agreed to cooperate in the joint development of pure electric vehicles because they believe that in order to mitigate global warming, reduce CO2 emissions and further popularize pure electric vehicles, it is necessary to transcend the constraints of competition and seek common development.

In the future, BYD and Toyota will combine their respective technology accumulation and development strength in the field of electric vehicles and batteries to develop more attractive pure electric vehicles and promote the further popularization of pure electric vehicles.

2019年7月19日，比亚迪股份有限公司（以下简称比亚迪）与丰田汽车公司（以下简称丰田）签订合约，共同开发轿车和低底盘SUV的纯电动车型，以及上述产品等所需的动力电池。车型使用丰田品牌，计划于2025年前投放中国市场。

比亚迪（BYD，全称BuildYourDreams）于1995年起步于电池事业，掌握电池、IGBT、电机、电控等电动车的核心技术，现已成为能够提供包括电动车以及动力电池在内的新能源整体解决方案的企业。比亚迪于2008年推出世界首款量产的插电式混合动力车型（PHEV），并从2015年起，连续四年实现了新能源汽车（PHEV和EV）全球销量第一。

丰田于1997年推出世界首款量产混合动力车型以来，作为开发电动车领域的先驱，在研发、制造、销售方面具备丰富的技术和经验。

平台开源优越性

在BNA设计中，有一个核心的革命性观念——"开放"。比亚迪倾力打造出的DiLink智能网联系统和D++开放生态，是开源的车载智能开发平台，可以为开发者提供开放的接口、车辆数据和控制权限。

比亚迪这套基于电动车业务平台的开源性和电池业务的搭配，应该可以看作是比亚迪在2019年抛出的一套强有力的组合拳，对比亚迪而言，平台对外开放，能够帮助比亚迪在动力电池和以及电驱动等领域，相比于竞争对手拥有差异化的竞争优势。比如，与宁德时代(72.500,1.00,1.40%)相比，比亚迪不仅能够提供动力电池，还能提供整体的电动车基础结构解决方案。

而对丰田等巨无霸式车企而言，其最大的吸引力在于——首先在中国本土市场，签约比亚迪可以获得一个长效的电池供应商解决方案，大型车企在面对未来市场高速扩张时，必须能够确保核心部件——动力电池的供应安全，而比亚迪作为一个最大的可选项，显然比当下众星捧月式的宁德时代更具吸引力，而且考虑到宁德与诸多跨国车企已经存在合作关系，丰田不把鸡蛋放在一个篮子里的做法也有利于保持其专利技术保持市场先进性。

而更为重要的是，丰田当年本不是不做电动汽车，而是在折戟电动车或者说起了个早市，市场觉悟太早但没有赶上中国这一庞大的新能源消费市场启动，从而在上世纪末至本世纪前10年才采取了混动这一折衷路线，能够和比亚迪这样与特斯拉同期开展全球电动车业务的车企合作，而且比亚迪主动抛出了开源平台的条件，这是任何一家精明的车企所不应该拒绝的邀约。

丰田比亚迪联手必要性

值得注意的是，工业及信息化部在6月24日已明确表示，已经废止电池供应商的建议清单，即符合条件企业目录俗称（动力电池白名单）。多家外国电池企业称借助目录放开，可望打开这一全球最大电动车电池市场的大门。

如果看清中国工信部的潜台词，则是意味着长达4年之久或者更长周期的中国动力(23.780,0.12,0.51%)电池扶植政策，伴随诸如宁德时代、比亚迪在内的一干主流企业在国际市场上站稳脚跟，将打破目前的“内外有别”的补贴格局，走向更有利中企外企同台竞争的格局。

而作为去年刚宣布放开动力电池供应，并在市场占有率上紧追宁德的比亚迪，则更有充分的理由在这个“寡头巨变”的时间段里迭代自己的核心竞争力，丰田的背书，带来的另外一层意义是：比亚迪对于其他潜在合作伙伴的“教育”工作将大幅减少。

而之于锐意改革的丰田汽车社长丰田章男而言，纯电动产品如果不能获得成本竞争力，将很难与燃油车有效地竞争，他需要在丰田体系内说服内山等旧臣完成丰田在21世纪的积极转向，而说服一帮老汽车人最好的方式——对于电动车产品而言，要获得成本竞争力，需要降低研发的分摊，降低固定资产（制造成本）的分摊和降低采购成本。

从这个层面上看，规模就会变得极端关键。这也是为何在日本市场，丰田会联合铃木、马自达、斯巴鲁、大发和日野，共同研发电动车基础平台的原因，而在中国市场，除了宁德时代以外，本土最大的动力电池出货商之一和最具制造经验的比亚迪恰恰是丰田应该选择战略合作的主要对象，这也是为什么连续多年奔驰坚持和比亚迪合作，即使在“腾势”项目出现暂时困难的情况下依旧不离不弃的原因之一，因为，放弃就意味着一无所获，而保持接触甚至在可能的空间中开展战略合作，不失为当下的传统车企在汽车四化战略转型中多点投注的妥当做法。

双方认为，为了减缓全球变暖，减少CO2排放，以进一步普及纯电动车为目标，有必要超越竞争关系的束缚，寻求共同发展，因此在纯电动车型共同开发方面达成了合作。

今后，比亚迪与丰田将结合各自在电动车和电池领域的技术积累和开发实力，致力于开发更具吸引力的纯电动车产品，推动纯电动车的进一步普及。
