AC charging pile solution

AC charging pile is a kind of equipment that provides energy for electric vehicles. It directly adopts the standard 220V AC with low power (within 10KW and usually 3KW/7KW) and slow charging. When charging the vehicle, the battery needs to be charged by the on-board charger, and the function of the pile is mainly to realize human-computer interaction, card swiping, billing and other functions. Zhiyuan Electronics provides core board, interface isolation, RFID card reading and other products for AC charging pile applications and offers all-round technical support services, which can accelerate your product development and seize the market.

Recommendation of system products

Core board

The technical complexity of AC pile is low, and the performance requirement of master control is not high. However, the cost is relatively high. The embedded MR6450 core board developed by Zhiyuan Electronics meets the application requirements.

Product features

  • Massive peripherals, easy data acquisition control (15-channel UART, 4-channel CANFD, etc.)
  • Simple development (AWorksLP “one-time programming, lifetime use, cross-platform”)
  • Industrial grade, no fear of cold and heat (-40℃~+85℃)

RFID card reading

Generally, AC piles are equipped with 13.56MHz card reading function through which users can use special cards for charging the piles. ZSN603 smart card reading chip developed by Zhiyuan Microelectronics has high integration and supports multiple protocols, which can accelerate product development.

Product features

  • Simple development (high integration, multiple protocols, instruction control)
  • Support multiple card types (Mifare S50/S70/Ultralight, second-generation ID card, etc.)
  • Industrial grade, stable and reliable (-40℃~+85℃)

Power isolation

Power supply is indispensable in electronic products. Generally, the pre-stage power supply controlled by AC charging pile needs isolation protection to ensure the safety of the motherboard, while other parts are not demanding. Zhiyuan Electronics wide-voltage isolated DC-DC power supply can provide stable and reliable driving voltage for user systems, and effectively solve the problem of unstable power supply caused by static electricity and surge. It is an ideal choice for board-level DC power supply.

Product features

  • Small size, high efficiency
  • Stable and reliable, no fear of “hot” and cold working conditions
  • Integrated protection against undervoltage, overvoltage, overcurrent and short circuit

Bluetooth module

In general, the demand for Bluetooth on AC piles is mostly used for household personal piles. Public piles are generally used for maintenance and debugging by manufacturers. Users control the work of charging piles or obtain information such as status, and the after-sales personnel of manufacturers maintain and debugging equipment. The master-slave integrated domestic Bluetooth module ZM8258P developed by Zhiyuan Electronics is suitable for this application scenario.

Product features

  • Small size, high performance, and low power consumption
  • High speed, multi-master and multi-slave, supporting OTA
  • Serial port control, simple development
