Functions

car_calc_e_bat(→ float)	Calculates the energy amount of electric car after power influence (from last step).
car_set_energy_within_limit(→ float)	Check that battery energy limits are not surpassed.
car_calc_power_limits(→ tuple[float, float])	Calculate the maximum (dis)charging power for the car battery.
car_calc_power(→ float)	Calculate the power at the current time step within the (dis)charging limits.

car_calc_e_bat(step_size: int, ev_data: eelib.data.EVData) → float

Calculates the energy amount of electric car after power influence (from last step).

Parameters:

• step_size (int) – simulation step_size

• ev_data (EVData) – contains all information of electric vehicles

Returns:

new energy level of electric vehicle (for next step)

Return type:

float

NOTE: This function was created based on the function step() in car_model

car_set_energy_within_limit(ev_data: eelib.data.EVData) → float

Check that battery energy limits are not surpassed.

Parameters:

ev_data (EVData) – contains all information of electric vehicles

Returns:

updated energy level of electric vehicle

Return type:

float

NOTE: This function was created based on the function set_energy_within_limit() in

car_model.

car_calc_power_limits(step_size: int, ev_data: eelib.data.EVData) → tuple[float, float]

Calculate the maximum (dis)charging power for the car battery. depending on the power limits and the current stored energy.

Parameters:

• step_size (int) – simulation step_size

• ev_data (EVData) – contains all information of electric vehicles

Returns:

minimum charging (resp. max. discharging) power of EV float: maximum (charging) power of EV

Return type:

float

NOTE: This function was created based on the function _calc_power_limits() in car_model.

car_calc_power(step_size: int, consumption_step: float, p_set: float, ev_data: eelib.data.EVData) → float

Calculate the power at the current time step within the (dis)charging limits.

Parameters:

• step_size (int) – simulation step_size

• consumption_step (float) – consumption at the current time step

• p_set (float) – set value for charging power of car

• ev_data (EVData) – contains all information of electric vehicles

Returns:

electric power of the vehicle

Return type:

float

Note

This function was created based on the function __calc_power() in car_model.
