/* * An example showing how to use the CANnucleo library: * * Two affordable (less than $3 on ebay) STM32F103C8T6 boardss (20kB SRAM, 64kB Flash), * (see [https://developer.mbed.org/users/hudakz/code/STM32F103C8T6_Hello/] for more details) * are connected to the same CAN bus via transceivers (MCP2551 or TJA1040, or etc.). * CAN transceivers are not part of NUCLEO boards, therefore must be added by you. * Remember also that CAN bus (even a short one) must be terminated with 120 Ohm resitors at both ends. * * For more details see the wiki page <https://developer.mbed.org/users/hudakz/code/CANnucleo_Hello/> * * NOTE: If you'd like to use the official NUCLEO boards comment out line 22 * * The same code is used for both NUCLEO boards, but: * For board #1 compile the example without any change. * For board #2 comment out line 23 before compiling * * Once the binaries have been downloaded to the boards reset board #1. * */ //#define TARGET_STM32F103C8T6 1 // uncomment this line when using STM32F103C8T6 boards! //#define BOARD1 1 // comment out this line when compiling for board #2 //CAN devices IDs and reserved ID's----------------------------------- //ID|Device //9|ECU|Key switch //10|ECU|Charge/discharge //11|BMS1|Cell voltages //12|BMS2|Cell voltages //13|BMS3|Cell voltages //?|Charger| // //------------------------------------------------------------------- /*************Zivan NG3-G7MICB Charger(Input 230VAC-19A;Output 96 VDC-25A)***** Processo de carregamento: (1) Desconectar carregador da rede AC (2) Conectar carregador as baterias (3) Conectar carregador da rede AC(talves mais pratico ter botao?) (4) Carga iniciase automaticamente(?) até uma tensao maxima de 4*27=108V (5) Para desligar carregador desconectar da rede AC Tarefas: -ver celulas em que o balanceamento nao esta a funcionar -ver porque as tensões nao se estão a actualizar (por a fazer display da soma das tenções) -ver porque o charger nao responde as mensagens CAN -acabar de formatar o codigo do BMS encurtando interrupts, programando todas as BMS's e aumentando fiabilidade, etc -ligar carregador e ver que tensoes de CAN e de saida manda cá para fora+ ver que mensagens Atenção: -obrigatorio conectar e desconectar as baterias do carregador quando este esta desconectado da rede AC -em caso de algum problema desligar primeiro ficha da redeAC do carregador e depois desconectar ficha das baterias Mensagens: (charger CAN node is 11 by default.
