Infrastructure Issues for Electric Vehicle Deployment in Ireland - ESB Networks

Infrastructure Issues for Electric Vehicle Deployment in Ireland Conor GarriganESB NetworksRegulatory Background•Generation :ESB PG plus independent generators•Transmission TSO: – Eirgrid•Distribution DSO: – ESB Networks•Supply : ESB Customer Supply ( PES) plus independent SuppliersWhat does this mean for the consumer?• Consumers have a direct relationship with both ESB Networks and their chosen supplierConsumerESB NetworksSupplier•Market Systems •Work Processes•Commercial arrangementsFocusing on the first element – Network connection• Where do we expect to have charging points– Domestic– On Street– Car Parks • Shopping Centres, Offices, Apartment blocksWhat are the expected charging requirements.ChargeFunctional NeedPower (kW)Standard100%36-8 hoursEmergency24km25in 10minsFast80%120in 10minsEV infrastructure what do we needNetwork connectionCharging EquipmentICT PlatformCan I charge my EV at home ?•We already have 2M connections nationwideBattery Capacity kWh•Typical charge rate available 3kwh4035•This should be sufficient for most batteries on an overnight charge.3025•So the answer is Yes…but with 20Battery Capacity kWhlimitations15•Battery Technology rapidly improving105–Higher capacity batteries with shorter charging times0–Increased demand for three phase Toyota G Wiz SMART VoltBYD F6 A class Mini Echarging PHEVFor twoEVSo what’s the impact of home charging on the Network• As EV penetration increases , we could find that the Low Voltage network and potentially the supply levels to houses will need to be reinforced and increased.• Typical system peak is between 5-7 pm, an appropriate mechanism for managing EV charging over this period would be required.• But that’s all part of the normal management of the network.I forgot to charge my car at home –On street•Expected to be used during day time by commuters.•Existing LV cables in the streets of many urban areas.•Easier to provide higher capacity charging than domestic situation– 3 phase supplies available.•Metered connection of up to 45kVA to be distributed to individual charge points.•Opportunity for a flexible arrangement for options of single/three phase and varying capacities .How would Networks do thisLV cable in streetCharge pointsCharge pointsNetwork Pillar
