Hybrid Electric

On the long straight road of one proving ground of Ministry of Communications, in order to study the influence of brake energy regeneration system (BERS), gear on coasting resistance, road coasting tests of a HEB were carried out under different conditions, separately on and off of BERS, neutral gear and gearing up. Test results showed, the regeneration brake force generated during the process of brake energy regeneration had quadratic relationship with vehicle speed, which had the greatest impact on coasting resistance; Coasting resistance under gearing up increased basically in proportion with rise in vehicle speed, and were about 2200N higher than those under neutral gear. When carrying out HEB road coasting tests, the BERS should be turned off, the transmission should be in neutral gear.

Fuel Cell Hybrid

Based on the Matlab/Simulink module modeling for Fuel Cell Hybrid Electric Vehicle was carried out, which is comprised of the fuel cell stack model, a DC/DC converter model, a battery model, a motor model, avehiclemodel and a driver model, and Hybrid Control Unit(HCU) was developed. The HCU control strategy also incorporates regenerative braking and recharge for battery capacity recovery. Vehicle speed effect is evaluated in New Europe Driving Cycle. The simulation result that the control strategy implemented by HCU is achievable, and which proves that the mode of Start, Accele_FCBat, Cruise, RE_Brake, Power_FC and Pause operate sequently as well as reliably.
