Boost Charger

What are some key differences between Boost Charger and other direct current fast chargers (DCFCs)?

  1. Boost Charger has an integrated lithium-ion battery pack with 160 kWh of total energy storage capacity.
  2. Boost Charger can provide fast charging to two EVs simultaneously.
  3. Boost Charger outputs up to 200 kW to an EV while drawing up to 27 kW from the grid. Boost Charger is compatible with low-voltage input, significantly reducing peak energy demand.
  4. The integrated design of Boost Charger results in an up to 5X smaller footprint compared to traditional fast chargers.
  5. Boost Charger can be configured with two CCS or two CHAdeMO connectors or one of each.

What’s the charging speed of Boost Charger?
Boost Charger has a maximum output per connector of 200 kW, delivering approximately 200 miles in 15 minutes. A single EV can charge at 200 kW, or two EVs can charge simultaneously at 100 kW.

How many EVs can be charged per day with Boost Charger?
Boost Charger discharges up to 200 kW of power to EVs primarily from its 160 kWh integrated energy storage, drawing up to 27 kW from the grid. The total number of EVs each Boost Charger can charge per day depends on a number of factors, including the EV’s power requirements, frequency, and duration of charges on a given day. Boost Charger is capable of providing over 2,000 miles (3,200 km) of range in a day, enabling a throughput of up to 20 vehicles per day. If the onboard battery is depleted, Boost Charger still passes through electricity from the grid. View a demonstration of Boost Charger dynamic charging in this video.
Can Boost Charger operate without cellular connectivity?
FreeWire’s standard Boost Charger requires cellular or ethernet connectivity to enable payment functionality and monitor system health. Contact a FreeWire representative to discuss options available at your site at

As a Boost Charger owner, how do I control charger pricing?
FreeWire customers are in full control of pricing, with the flexibility to implement rules to promote dwell time or incentivize driver behavior within applicable state guidelines. Pricing can be customized through the selected charging network and easily managed through an online interface. Currently, 30 states allow kWh pricing instead of charging per minute, as kWh pricing is widely viewed as the fairest and most straightforward pricing method.

What data and information are accessible for owners or site hosts from Boost Charger?
Boost Charger site hosts have access to detailed data on charging sessions, utilization patterns, revenue, and environmental impact through emission reduction calculations.

How long does it take to fully recharge Boost Charger from empty?
Under normal operating conditions, customers will likely never deplete the Boost Charger battery. If they do, Boost Charger can fully recharge in approximately 8 hours.

What incentives are available in my state?
Many states offer significant incentives for EV chargers. Contact a FreeWire sales representative to learn how state and federal incentives can reduce your Boost Charger procurement cost.

What electrical capacity or service is needed on site for Boost Charger?
Unlike most traditional DCFCs that would require high voltage (480 V) infrastructure, Boost Charger is compatible with standard split-phase 240 V connections, three-phase 208 V or 400 V connections. Boost Charger can be powered with lower electrical input levels if higher electrical input is unavailable. For maximum power to recharge the Boost Charger battery, the 240 V installation would use a 150 amp circuit, the 208 V would use a 100 amp circuit, and the 400 V would use a 40 amp circuit.

How much ground space is required?
Boost Charger occupies a 40″ (101 cm) x 43″ (109 cm) footprint. Additional space may be required for bollards or other protection based on site owner preference or local permitting requirements.
