DC EV Charger Feature Differences

Power Output and Charging Speed

DC EV chargers, also known as DC fast chargers, can provide much higher power output and faster charging speeds compared to Level 1 or Level 2 AC chargers. DC fast chargers with power levels from 20kW up to 350kW are available. The maximum power dictates charging speed – a 50kW charger can add about 100 miles of range to an EV in 30 minutes. For businesses looking to maximize charging turnover, higher powered 150-350kW systems allow an EV battery to reach 80% in 15-30 minutes.

Connector Types

DC fast charging requires specialized connectors like CHAdeMO, CCS, GB/T, or Tesla. CHAdeMO and CCS are the most common internationally. CHAdeMO plugs directly into compatible Japanese and Korean EVs like Nissan Leaf. The Combined Charging System (CCS) connector has become standard for European, American, and an increasing number of Asian EVs. For compatibility with the widest range of EV makes, DC EV chargers with both CHAdeMO and CCS are recommended.

Flexible Deployment

DC fast chargers are available as both floor-mounted towers and wall-mounted compact units. Floor-mounted systems have a small footprint and can be installed in parking lots and along highways. Wall-mounted compact chargers can attach to AC charging stations and buildings in space constrained areas. Portable ruggedized wheeled cart models also enable flexible placement for temporary high capacity charging at events.

Demand Charges Mitigation

The 50kW+ capacity of DC fast chargers can significantly increase demand charges from high instantaneous power draw. Smart DC chargers have integrated energy storage buffers that can shave peak loads. This helps businesses and charging networks limit demand charges that would otherwise drastically cut into profits. We offer optional 200kWh-1MWh battery buffers.

Advanced Load Management

Our DC chargers have integrated networking and smart charging functionality. This enables remote control and scheduling of charging based on time-of-day utility rates. It also allows charging output to automatically adjust dynamically based on available supply capacity to avoid overloaded circuits.

Supply Infrastructure Requirements

The high power output of DC fast chargers necessitates robust supporting electrical infrastructure. The 50-350kW unit may require new medium voltage utility service and transformers. We offer full-service consultation to analyze your site capacity, plan electrical upgrades, coordinate with utilities, manage construction, and integrate storage buffers to cost-effectively deploy DC fast charging.

Extreme Environment Protection

Our fast chargers utilize industrial-grade components and rugged enclosures to withstand extreme environments with -30 to 50°C temperature rating and IP65 ingress protection. Options like snow melt mats, hydraulic auto-raising cables, and heated connectors prevent winter weather disruption. The advanced liquid cooling system enables reliable operation even in scorching climates.

Remote Monitoring and Diagnostics

All our DC EV chargers come with gateways to our cloud-based monitoring platform that tracks live charging status, usage, diagnostics etc. If issues arise, the remote connectivity enables our technical staff to quickly diagnose problems and deploy over-the-air updates for increased uptime. The open APIs also allow integration with third-party management software.

Warranties and Service

We provide minimum 3 year comprehensive warranties standard with options for extended 5 year coverage. For non-hardware issues, remote diagnostics and OTA updates resolve the majority of problems within hours without needing on-site repair. For hardware replacement/repair, we have local technicians nationally to respond quickly under warranty or paid service contracts.
