Abstract
Research on optimization of control strategy for hybrid energy storage system (HESS) of the electric vehicle (EV), a new adaptive control strategy based on particle swarm optimization (PSO) algorithm is proposed in this paper. The steady-state power of the filtered power is used as the ideal output power of the battery. For the steady-state current output of the battery, the output power of the ultracapacitor is dynamically adjusted by the proportional-integral-derivative (PID) controller to construct a power difference control structure. The parameters of PID controller are optimized by PSO algorithm, and the target test is compared and analyzed based on MATLAB/Advisor. The research results show that the proposed PSO-PID control strategy can quickly eliminate the power deviation and achieve the approximate global optimization of the EV energy management strategy. Compared with the pre-optimized PID control strategy, the output current and power of the battery pack are smoother and the total power consumption is reduced by 3.8360% and 0.5125%, respectively. Then, the energy consumption parameters of PSO-PID are compared with the theoretical minimum energy consumption calculated by dynamic programming (DP) algorithm, and the deviation is less than 1% under both conditions.

Automobile brings convenience to human beings and challenges to environmental pollution and energy crisis at the same time
The results show that the theoretical minimum energy consumption in UDDS is only 0.9066% lower than that in particle swarm optimization (PSO)-PID, and 0.2245% lower in NEDC
On this basis, using PSO algorithm to optimize the parameters of PID controller, and puts forward the PSO-PID energy management strategy
Summary
Automobile brings convenience to human beings and challenges to environmental pollution and energy crisis at the same time. New energy vehicles are the focus of automobile industry research. Different from traditional fuel vehicles, new energy vehicles can effectively reduce the dependence of vehicles on fossil fuels. EV has the advantages of zero emission and low running noise, but its development is subject to technical obstacles such as short and unstable mileage, battery life, and lack of power during heavy load operation. Single energy storage system can not meet the requirements of EVs, the HESS is needed to ensure the mileage and power performance of the vehicle. HESS is composed of high energy density battery and high power density ultracapacitor. The adoption of appropriate energy management strategy for the composite power system has a great impact on the battery cycle life, vehicle power
