slide show that develops the concept and benefits of automated electric vehicle
charge control using current sensing technology and charger modulation (or
charger dimming), from idea to realization.
owners of charge stations a simplified process of planning for intallation.
Convincing EVSE manufacturers that a variablegrid add-in gives their customers
added reasons for buying their equipment. Designing variablegrid controls
that provide immediate advantages without affecting future smart grid interfaces
to the EVSE or the vehicle.
new, rational, elegant and lower cost solution toward integrating the smart
grid and the electric vehicle using a client-server network capable of shifting
power to where and when it's needed without overtaxing existing equipment.
supply circuits of any rating can now directly support Level 1 and Level 2
electric vehicle charging using the concept of elastic charging; the electric
vehicle is charged at a much faster average rate by automatically taking advantage
of periods of reduced electrical consumption.
powering electric vehicle charging equipment with variablegrid, changes
to house wiring can be minimized or postponed. Regardless of electrical service
level, your dedicated charging circuit can be the same rating as that of your
main service level - just by adding a subpanel. There is no need for complex
electrical load decisions, let alone (very) expensive changes to your electrical
service. Variablegrid operates as an add-in to current EVSE's that have a
smart grid board, or as an add-on to those that don't.
solves the problem of electrical distribution capacity planning in condominiums
and electric vehicle group charging environments. It pools electrical power
and allocates it dynamically on an equitable basis. It can also save a lot
of copper by making bus-wiring possible.
connected to a communications module implementing control protocols that connect
to an electric vehicle charge station. Using unbreakable encryption this paradigm
prevents logical theft, since without the network the EVSE is "brick'd."
Automated management of unpredictable electrical
demand patterns as a result of clustering of EV's. Real-time computer-based
control network for new (continuous) load types. Variablegrid reduces or
eliminates the need for active economic demand shaping with respect to electric
vehicle loads. Enables automatic unloading of EV loads on the low-voltage
grid, to counteract blackstart recovery transients.
