Conventional EV charging systems only go one way – from the electric grid to an EV. A bidirectional charging system both charges and discharges an EV’s battery. This expands the value provided by EVs, turning EVs into “batteries on wheels” and enabling EVs to send energy stored in the onboard battery to the local utility…
Unidirectional charging only sends energy one way – from the grid to the EV, making a single directional charger a constant cost center. A bidirectional charging system does more; it both charges an EV and discharges some of the energy stored in the battery to the grid or to a building. The decision whether to…
Vehicle-to-everything (V2X) bidirectional charging systems allow for bidirectional (back and forth) power flow between an EV and other loads that need energy, such as the grid, a building, a home, or other connected devices. V2X includes V2G (vehicle-to-grid), V2B (vehicle-to-building), and V2H (vehicle-to-home) systems. V2X requires a bidirectionally-enabled EV, a bidirectional EV charger, and software…
Vehicle-to-grid (V2G) systems leverage a bidirectional EV charging platform to send (discharge) some of the energy stored in a parked EV’s battery to the grid when utilities need it most, for example, for a few hours in the late afternoon on a hot summer day. EV fleet operators/owners using V2G bidirectional charging systems (software and…
Vehicle-to-building (V2B) systems leverage bidirectional charging to send energy stored in an EV’s battery to a building. This enables commercial building owners, operators, and tenants to better manage their electricity usage and reduce electricity bill costs by avoiding costly peak demand charges. In some instances, the energy stored in an EV’s battery can be used…
Vehicle-to-home (V2H) systems leverage bidirectional charging to send energy stored in an EV’s battery to a user’s home. This allows an EV to power a home in case of a grid blackout. It can also enable the user to selectively reduce their load in response to their utility’s request for energy reduction. A V2H system…
V1G, also known as “managed” or “smart” charging, uses unidirectional charging, which only goes one way – from grid to vehicle. V1G ensures that EVs are charged when they need to be driven while avoiding excessive charging when electricity rates are high. V1G functions to avoid charging at potentially costly times (as much as possible), but…
Fermata Energy is the only V2X/ V2G platform with customers today who are earning thousands of dollars every year with a single EV paired with just one bidirectional charger. Two earning examples: Commercial customer A participates in a V2G program, using one 15kW bidirectional charging system and one bidirectionally-capable EV. The cost to charge for…
Demand for electricity increases on hot summer days and cold winter days. These periods of high demand can strain the grid, raising electricity costs, and potentially causing brownouts or black outs. Utilities manage these high load periods with “demand response” (DR) programs that create incentives for their customers to reduce or shift their electricity use…
Demand charges are part of many commercial and industrial electricity bills and are based on the highest amount of power (kW) consumed over a 15-30 minute period during a customer’s monthly billing period. Some utilities charge customers very high costs per kW for these periods of highest use. These customers can reduce the demand charges…
