实现电动汽车快速充电的大功率解决方案
随着市场上电动汽车数量不断增长，以及各国政府要求最迟在 2050 年前实现汽车排放归零的压力，人们迫切需要更为高效的充电解决方案。正如各类消费者研究所示，用户对电动汽车的接受程度深受充电过程的有效性和时长影响，而大功率直流充电站就是满足此类市场需求的解决方案。如今，常规电动汽车可在 10 分钟内充满 80% 的电池容量。该充电速度堪比使用内燃机的传统汽车加油速度。

从控制、感测到高等级安全性和连接性的先进解决方案
针对功率高达 150 kW 的直流电动汽车充电设计，英飞凌可提供高性价比的分立式产品。其中包括 600 V CoolMOS™ 超结 MOSFET P7 和 CFD7 系列、650 V IGBT TRENCHSTOP™ 5 和 1200 V CoolSiC™ MOSFET。CoolMOS™ 和 CoolSiC™ MOSFET 的突出优势在于支持高频运行、功率密度高且开关损耗低，可有效提高各类电池充电系统的效率。 高压开关产品系列则新增 650 V 和 1200 V CoolSiC™ 肖特基二极管。由于各开关均需驱动器，且每个驱动器都需要控制，我们还提供适配的 EiceDRIVER™ 栅极驱动器以及用于电动汽车充电的 XMC™ 和 AURIX™ 微控制器。OPTIGA™ 产品丰富了产品组合，主要用于保护数据和信息安全。功率在 50 kW 以上的充电器通常采用 IGBT CoolSiC™ MOSFET 和二极管电源模块，如CoolSiC™ Easy 模块、IGBT EconoPACK™ 及 IGBT EconoDUAL™ 系列。容量高于 100kW 的充电桩则一般使用堆叠子单元的模块化结构。如今此类子单元的单位容量已达 20-50 kW，并有望在未来产品中继续扩容。
推广全球标准
英飞凌是全球电动汽车充电接口倡议组织 (CharIN) 的成员。CharIN 的目标是起草、制定和推广针对各种电池供电型电动汽车的全球充电系统标准。
大功率直流充电器通常会将三相交流电转换为车辆电池所需的直流电。数据传输通道则用于交换车辆和电池充电状态相关信息。最后，通过安全数据通道发送车辆信息和车主数据以便计费。
直流快速充电器架构的三大主要挑战在于尽可能降低冷却工作量、实现高功率密度和缩减整体系统尺寸和成本。当下，高功率密度设计的标配是强制风冷。但因系统功率密度提升，下一代充电解决方案则需采用液冷措施。紧凑型设计必须具备更高的开关速度（32 kHz 到 100 kHz 范围内）以减少磁性元器件的尺寸。
全球大多数主要城市均最迟在 2050 年前实现零排放，这一战略的落实有赖于提高电动汽车使用量，因此需要更优质的快速充电基础设施。城市高污染损害了居民的健康和生活质量，这无疑也是实现上述目标的动力。零排放或低排放出行有助于减少空气污染导致的健康问题，如心血管疾病和哮喘。
好消息是到 2025 年，届时将有超过 100 款新型电动汽车上市。此类提升城市空气质量的举措进一步加大了研发和构建充电基础设施的压力，这些基础设施用于容纳更多上路的电动汽车。由于市区空间有限，私人设施无法满足日后的充电需求。因此，公共充电器对增强城市电动汽车可用性而言愈发重要。最后，伴随电池制造商的成本结构优化和规模经济改善，电动汽车的购买吸引力之强前所未有。
摆脱充电枪和电缆的限制，无线充电系统实现了无线电力传输。这一感应式充电技术可通过停车位地面的线圈将电能传输至车辆内置线圈，从而完成充电。
无线电力传输 (WPT) 特性：
- 功率等级：3.7 kW、7.7 kW、11 kW
- 静态 WPT：车辆未行驶时充电
- 动态 WPT：在车辆行驶在支持 WPT 的道路上时充电
在车内进行 DC/DC 转换以使输入电压适配转换器
探索无线电力传输系统图：
DC-DC 级结构可基于不同的电源转换拓扑。通常首选谐振拓扑以便减少开关损耗。DC-DC 级安装于车内，可根据电池要求调整输出电压。
无线电能传输装置通常使用分立式解决方案，如 CoolSiC™ MOSFET、CoolSiC™ 二极管和 CoolMOS™。由于各开关均需驱动器，且每个驱动器都需要控制，我们提供适配的 EiceDRIVER™ 栅极驱动器 IC 以及 XMC™ 微控制器。我们的 XENSIV™ 电流传感器亦可助力打造精准的小型电流感测解决方案。OPTIGA™ 产品丰富了产品组合，可用于保护数据和信息安全。
电动汽车在充电点充电时，必须能够识别、验证和保护在充电器、车辆和后台基础设施之间传输的信息。这便需要加密技术来保护充电基础设施和相应车辆。
作为 ISO 15118 国际标准的一部分，即插即充方案应运而生。依托该方案，车辆无需向充电站出示专用充电卡即可充电。这一电动汽车充电方式安全便捷，涵盖基于交流和直流子系统的有线及无线充电技术。即插即充技术是其核心，旨在通过 ISO 15118 标准规定的对称和非对称加密算法来确保机密性、数据完整性和真实性。
该标准可通过诸如英飞凌可信平台模块 OPTIGA™ TPM SLI 9670 等防篡改微控制器实施，此类标准组件符合可信计算组织 (TCG) 的 TPM 标准。通过保护所涉实体的真实性、交换数据的完整性和敏感信息的机密性，TPM 在保障即插即充方案的金融交易安全方面起到了重要作用。
此外，OPTIGA™ TPM SLI 9670 还可用于保护平台，实现服务器后台、充电站和电动汽车之间的安全数据传输。上述特性旨在确保固件更新、维护和管理充电基础设施设备等远程功能的安全。
