Cost-efficient and smart charging solutions
The planned demo action consists of assisting with the construction of a high-capacity bus depot to charge the existing and planned e-buses overnight, taking advantage of the electricity oversupply and a reduced electricity price at night. Once the demo action starts, there will already be 30 e-buses running in Montevideo and the bidding process for the next 40 will have started. The high-capacity bus depot will integrate efficient and cost-effective smart charging solutions compliant with Combined Charging Standard (CCS) and Open Charge Point Protocol (OCPP).
This will allow charging of up to 3 buses with 1 charger, i.e., 3 compact boxes powered by one charge cabinet that will charge 3 buses sequentially (up to 150 kW per bus) with all buses being charged within 6 hours. The main advantage of implementing this type of equipment is that the required grid connection is smaller, reducing initial investments and operational costs. The depot will serve a double purpose, as during daytime 10 E-taxis (provided by city/taxi) will have access to 15-30 minutes charges in the multi-standard 50 kW fast charging stations provided (ABB). Moreover, the possibility of installing opportunity fast chargers in the most travelled streets for buses to charge for 3-6 minutes on-route will be explored. These solutions can easily be integrated in existing operations by installing inverted pantographs and chargers at terminals and intermediate stops. Finally, a real-time platform for reliable and secure operation of electrical power networks, ranging from generation, transmission and distribution to e-buses will be developed to improve the system management. IDIADA will support the charging standardization.
