The demonstration of AFC Energy’s CH2ARGE system took place at Dunsfold Aerodrome, charging a BMW i8 as the first ever car to be recharged with power generated by a hydrogen fuel cell. The charger uses a fuel cell with an inverter to charge vehciles, using a 48V battery pack to meet peak power requirements.
The demonstration system was sized to provide sufficient power to charge two EVs concurrently at recharging levels 1, 2 or 3. The system’s inverters are controlled via AFC Energy’s fuel cell control system which ensures the safe and precise control of the complete setup. Being integrated into AFC Energy’s control system means that product solutions can be implemented with Smart Charging capabilities.
After 10 years of fuel cell research development, the company is preparing for the commercialisation of fuel cell-based EV Charge solutions to meet the growing demand for environmentally friendly power in the EV market. The UK government is aiming for half of all new car sales to be EVs by 2030, which will see nine million EVs on the road. By 2040, 100% of new car sales are planned to be EVs leading to the entirety of the UK’s fleet of 36 million cars becoming EVs.
To recharge the fleet of EVs, the UK National Grid estimates show this will require generation to be increased by 8GW, while calculations by AFC Energy show that if one in 10 of the EVs is being recharged simultaneously in the UK would have a peak demand surge of 25.7 GW based on an average EV battery of 57 kWh. This maximum peak demand equates to approximately half the UK current generational requirement and is the equivalent of 7.9 new nuclear power stations or 17,100 wind turbines. Popular venues such as sports centres, stadiums and supermarkets will also have to scale up EV recharging solutions; a scenario where 25% of vehicles are EVs and half plug in to charge while at the venue would require 11.5MW of electricity generation. Extensive investment in new power stations and upgrade of the distribution network would be required unless these demands are met through localised power generation.
The CH2ARGE system could potentially deliver locally-generated electricity through thousands of installations that generate 100% clean electricity. In contrast, the provision of power through central generation would require massive investment in new generating capacity and a re-architecting of the distribution network.
“By 2030, it is estimated that there could be nine million electric vehicles on the roads of Britain, up from 90,000 today,” said Adam Bond, Chief Executive Officer at AFC Energy. “For this transition, we need charging stations to be embedded throughout the country, as well as seeking innovative solutions to overcome the severe limitations of centrally generated electricity. By developing and demonstrating the effectiveness of our hydrogen fuel cell in the application of EV charging, AFC Energy has shown it is ready to lead the way not only in solving the challenges of increased demand for electricity, but also doing so in a truly zero emissions approach.”
AFC Energy is looking to enter into discussions with potential OEM partners and suppliers for the production of its CH2ARGEscalable EV Charge systems for commercial deployment.
