充电桩代码

充电桩的代码需要根据具体的硬件设备和控制要求进行编写和调试。以下是一个简单的充电桩代码示例，仅供参考：

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>

#define AC_INPUT_VOLTAGE 220  // 输入交流电压
#define DC_OUTPUT_VOLTAGE 400  // 输出直流电压
#define MAX_CURRENT 32  // 最大充电电流
#define MAX_CHARGE_TIME 180  // 最大充电时间

// 充电状态
enum {
    CHARGE_STATUS_IDLE,
    CHARGE_STATUS_READY,
    CHARGE_STATUS_CHARGING,
    CHARGE_STATUS_FINISHED
};

// 充电桩状态
struct ChargePileState {
    bool is_power_on;  // 是否通电
    bool is_connected;  // 是否连接电动汽车
    int charge_status;  // 充电状态
    int charge_time;  // 充电时间
    int charge_current;  // 充电电流
    int charge_voltage;  // 充电电压
};

// 初始化充电桩状态
void init_charge_pile_state(struct ChargePileState *state) {
    state->is_power_on = false;
    state->is_connected = false;
    state->charge_status = CHARGE_STATUS_IDLE;
    state->charge_time = 0;
    state->charge_current = 0;
    state->charge_voltage = 0;
}

// 设置充电电流
bool set_charge_current(struct ChargePileState *state, int current) {
    if (!state->is_power_on) {
        return false;
    }
    if (current <= 0 || current > MAX_CURRENT) {

    }

    return true;
}

// 设置充电电压
bool set_charge_voltage(struct ChargePileState *state, int voltage) {
    if (!state->is_power_on) {
        return false;

    if (voltage <= 0 || voltage > DC_OUTPUT_VOLTAGE) {
        return false;
    }
    state->charge_voltage = voltage;
    return true;

        return false;
    }
    state->charge_status = CHARGE_STATUS_FINISHED;
    return true;
}

// 更新充电桩状态
void update_charge_pile_state(struct ChargePileState *state) {
    if (!state->is_power_on || !state->is_connected) {
        state->charge_status = CHARGE_STATUS_IDLE;
        state->charge_time = 0;
        state->charge_current = 0;
        state->charge_voltage = 0;
        return;
    }
    switch (state->charge_status) {

            state->charge_current = 0;

            break;

            state->charge_time++;
            if (state->charge_time >= MAX_CHARGE_TIME) {

                state->charge_time = 0;
                state->charge_current = 0;

            break;
        default:
            break;

}

int main() {

        printf("充电状态：%d，充电时间：%d，充电电流：%d，充电电压：%d\n",
               state.charge_status, state.charge_time, state.charge_current, state.charge_voltage);
    }

}
