This raw result was corrected with the traction battery state of charge (SOC) variation, the 12 V network consumption deviation and the platform drag deviation. The raw result measured on the test bed was 111.1 gCO 2/km (shown in the orange box in the middle). The expected emission, estimated by simulation, was 106.7 gCO 2/km (shown in dark red on the left). Based on that tuning, the CO 2 measurements were performed. At the end of these optimization loops, the emissions were below the requested levels. The Figure shows the tuning loops that were necessary to comply with the Euro6b regulation. The demonstrator car has been built and tested within Renault’s facilities: the results are encouraging. The inverter for the e‑motor, which is integrated within the transmission, is connected directly to a side e‑motor.įigure 4 Demonstrator car at the EUCAR conferenve 2017 As can be seen, the 48 V battery is integrated in the rear of the vehicle, whilst the DC‑DC converter and the vehicle 14 V battery are integrated within the engine room.
