特性和优点

  • Complete reference design for Type 2 EVSE Cordset (IC-CPD)
  • Power level from 2.3 kW up to 3.6 kW
  • Designed to comply with the applicable standards - IEC61851, IEC62752
  • Incorporates a 6 mA DC/30 mA rms RCD and a control pilot circuit
  • Stuck relay detection and relay state of health
  • Overtemperature detection
  • Integrated isolation
  • Reduced component count for cost optimization
  • Bluetooth 5.2 interface for connectivity to external devices
  • Open-source software stack to enable custom firmware development

产品详情

The AD-ACEVSECRDSET-SL is a complete Type 2 EVSE 3.6 kW charging cable solution, providing a reference design intended for evaluation and prototyping of electric vehicle (EV) charging systems.

The system includes a 3-channel isolated sigma-delta (Σ-Δ) ADC for voltage and current measurement on the single-phase power input and measurement of the relay voltage for solder contacts detection and relay state of health. Safe operation is enabled by the inclusion of a 6 mA DC / 30 mA rms RCD. Detection of overvoltage, undervoltage, overcurrent, overtemperature and EV diode presence is also available.

A MAX32655 low-power, ARM® Cortex®-M4 Microcontroller implements the logic for system control and communication with the EV over the control pilot interface. A programming and debugging interface are included. The MAX32655 Bluetooth 5.2 interface enables connectivity to external devices.

The design is accompanied by an open-source software stack and reference applications, enabling custom software development to start from a proven implementation validated to meet the applicable standards. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug.

The system is designed to comply with the IEC61851 and IEC62752 standards.

产品详情

演示电路 SCP-LT8330-EVALZ 配有升压/ SEPIC /反相转换器 LT8330，并带有 1A、60V 开关。明确说该演示电路是升压转换器，工作输入电压范围为 10V 至 36V，输出电压为 48V。当输入电压为 12V 时，最大输出电流为 135mA。

像信号链电源系列中的所有电路板一样，该板可轻松插入其他 SCP 板中，以形成完整的信号链电源系统，从而能够快速评估低功耗信号链。要评估该评估板，需要一些通用的 SCP 硬件，即：

  • SCP-INPUT-EVALZ
  • SCP-OUTPUT-EVALZ
  • SCP-FILTER-EVALZ
  • SCP-THRUBRD-EVALZ
  • SCP-1X2BKOUT-EVALZ
  • SCP-1X5BKOUT-EVALZ
  • SCP-5X1-EVALZ

 

为了正确评估 SCP 系列演示板，您将需要 SCP Configurator 配套软件。SCP Configurator 可以帮助您为您的设计选择正确的电路板和拓扑。

请注意，演示手册并未涵盖关于 LT8330 的操作和配置的重要细节。有关该套件的完整说明，请参考 LT8330 数据手册。
