the Energy Hub Alliance platform
ELECTRIC VEHICLES
Connecting to OEM interfaces unlocks the most talked about data point for electric vehicles, the state of charge (SOC), this is the precise current level of energy in the car battery. With the SOC the energy demand of the EV charging schedule can be calculated and communicated to the other energy devices in the household.
USE CASES EXAMPLES
Solar optimized charging
Combine electric vehicle state of charge data with real-time solar production data to schedule the EV charging during peak solar production periods. Maximizing the use of renewable energy and minimizing reliance on the grid during peak demand times.
Driving co-ordinated heating
Schedule household heating to the vehicle driving schedule. Heat/cool the house before the vehicle arrives home and turn the heating/cooling off when the vehicle leaves.
Price optimized charging
With the current state of charging and driving schedule, the charging of the EV can be optimized with respect to dynamic electricity prices, minimizing energy costs for EV owners.
Smart Tariffs
Smart tariffs are fundamental to the modernization of household energy consumption. New electricity pricing models and real-time energy data enable the creation of intelligent, customer-focused energy solutions. Connecting to a smart tariff interface provides not only accurate energy consumption data, but also the electricity price or tariff details
USE CASES EXAMPLES
Price optimized everything
Considering dynamic energy prices, time shifting strategies can be applied to the schedules of EV charging, heating, cooling, water heating, and more.
Billing accuracy and transparency
With clear and correct pricing information, end customers understand their energy costs and the benefits to shifting their energy demand.
Heating & COOLING
Heating, ventilation, and air conditioning (HVAC) can account for a significant portion of a households energy consumption, particularly in middle of winter and summer. Connecting to a HVAC interface provides the current and the scheduled climate control for the household.
USE CASES EXAMPLES
Price optimized climate control
Considering target climate, heating and cooling can be shifted to time slots with low energy prices to avoid heating during high energy price slots.
Participate in demand response
Heating and cooling can be interrupted for a short time to ease the load on the grid. In general, the temperature of a room does not noticeably change from short interruptions.
SOLAR
Solar inverters are more intelligent than before. They’re able to not only convert solar energy to alternating current (AC) electricity, but also monitor the system, collect, and expose data. Connecting to a solar inverter interface gives valuable real-time and historical solar electricity production data.
USE CASES EXAMPLES
Excess solar charging
It is possible to decide what the solar energy is used for. Excess solar energy, not used by the house, can be sent directly to the EV to top it up while it is plugged in, maximizing self-consumption of renewable energy
Phase switching
The solar inverter can send detailed solar power output information (including the real-time power generation, voltage, and current) which enables an EV to switch between 3-phase and 1-phase charging. Allowing the EV to charge with solar energy even if the PV has low power generation
battery storage
Home battery storage systems are becoming more economically feasible, and households are expanding their energy ecosystem to include battery storage for storing power from solar panels. Connecting to a battery storage system interface offers valuable state of charge (SOC) data and the ability to control the charging and discharging of the battery.
USE CASES EXAMPLES
Participate in demand response
The battery storage can be connected to the smart tariff and rewards can be offered in return for the ability to control charging and discharging.
Optimize battery longevity
By using the battery storage with a HEMS, rules can be applied to prevent discharging beyond limits set by the user and rules can be defined for supplying energy to specific household devices..
HOME ENERGY MANAGEMENT SYSTEM
Home Energy Management Systems (HEMS) are becoming increasingly popular for monitoring and managing electronic appliances. By cleverly timing energy consumption to coincide with renewable energy availability, a HEMS cuts both expenses and environmental impact. Connecting to a HEMS interface provides home energy consumption patterns and appliance usage.
USE CASES EXAMPLES
HEMS vs EV prioritization
Prioritize vehicle charging against other appliances in the household. The vehicle charging is postponed allowing the washing machine to consume solar energy being produced.
Home energy usage influences route navigation
The navigation system of the EV considers current home energy usage and the EV charging schedule. Recommending an alternative route home that allows the vehicle to charge when the household energy demand is too high.
Intelligent peak shaving
By connecting to a HEMS, control signals can be sent to all household energy devices minimizing grid impact during peak demand, maximizing efficiency and reducing costs.
Charging hardware
Charging hardware provide the flexibility to charge at home and is the frequent favourite add-on for owners of electric vehicles. Connecting to a charging hardware interface provides information on the availability of the charging station, power level, charging duration, and more.
USE CASES EXAMPLES
Remote stop/start charging
Charging sessions may be accurately monitored and remotely controlled. This is especially useful for remote resets of the charging hardware (where applicable).
Shared charging station scheduling
For households with multiple EVs but only one charging hardware, the availability of the charging hardware can significantly impact the optimization of charging schedules.
