使用Python Simpy实时模拟电池充电

Question

我正在尝试使用Simpy进行模拟，以进行电池充电。所需的参数是电池容量（W），电池的充电状态（百分比）和充电器的充电功率（W/H）

我的代码看起来像这样：

import simpy
import random

battery_percentage = []

class ChargingCycle(object):
    def __init__(self, env, battery_capacity, SoC, charging_power):
        self.env = env
        self.battery_capacity = battery_capacity
        self.SoC = SoC
        self.charging_power = simpy.Resource(env,charging_power)

    def charge(self, battery):
        print(self.charging_power)
        power_per_minute = self.charging_power/60
        charge_in_kw = (self.SoC/100)/self.battery_capacity
        charge_in_kw += power_per_minute
        self.SoC = charge_in_kw/self.battery_capacity*100

    
def start_charging(env, battery, charging):
    with charging.charging_power.request() as request:
        yield request
        yield env.process(charging.charge(battery))
    

def run_charging(env, battery_capacity, SoC, charging_power):
    charging = ChargingCycle(env, battery_capacity, SoC, charging_power)
    battery = 0
    while True:
        yield env.timeout(1)
        battery += 1
        env.process(start_charging(env, battery, charging))

def main():
    env = simpy.Environment()
    env.process(run_charging(env,45000, 10, 7630))
    env.run(until=360)

if __name__ == "__main__":
    main()

基本上，我想为每一个获得充电能力分钟，每分钟，我将充电器给电池的电源添加到变量chode> Charge_in_kw，然后更新了电荷状态soc。

当我运行模拟时，我会收到此错误：

File "c:\Users\sc57978\Desktop\OCPP\sim_charge.py", line 17, in charge
power_per_minute = self.charging_power/60

TypeError: unsupported operand type(s) for /: 'Resource' and 'int'

有人知道如何解决此问题？

在运行和进行大量调试后，我能够运行您的代码，我进行了以下更改以使其运行以

• 从charging_capacity资源中获取值，以求解您
• 添加的实际错误suff suffer self self。 Env.TimeOut（1）解决电荷功能

最终运行代码的更多错误
