SOC = ones(size(t)); % State of Charge (SOC)
SOC(1) = 1; % Initial SOC (100%)
distance = zeros(size(t)); % Distance traveled (m)
% Driving Cycle (e.g., constant acceleration and deceleration)

F_rr = Crr * mass * g; % Rolling resistance
F_total = mass * accel + F_aero + F_rr; % Total force
% Update vehicle velocity
velocity(i) = velocity(i-1) + (F_total / mass) * dt;
% Ensure non-negative velocity
if velocity(i) < 0
velocity(i) = 0;
end
% Calculate motor power

motor_power = motor_power / motor_efficiency; % Account for motor efficiency
% Update SOC
battery_current = motor_power / V_batt;
SOC(i) = SOC(i-1) – (battery_current * dt) / Q_batt;
% Ensure SOC does not go below 0
if SOC(i) < 0
SOC(i) = 0;
break; % End simulation if battery is depleted
end
% Update distance traveled
