Coulomb Solutions Inc. Launches 40kW On-Board Charger and EVSE for Commercial Vehicles

Posted

Coulomb Solutions Inc. (CSI) has commenced production of its latest innovation in commercial electric vehicle (EV) charging technology: the 40kW On-Board Charger and Electric Vehicle Supply Equipment (EVSE) Combo. First introduced at the Advanced Clean Transportation Expo (ACT Expo) in Las Vegas last May, this new charging solution addresses critical infrastructure challenges faced by fleet and bus operators. The system enables vehicles to be charged overnight using existing infrastructure, eliminating the need for immediate electrical service upgrades or the installation of costly DC fast chargers.

Key Features and Benefits

The 40kW AC EVSE and On-Board Charger Combo by CSI is designed with versatility in mind. It is compatible with a wide range of standard and existing outlets, including those typically used for welders, appliances, and vehicle lifts. The system supports inputs of 208V, 220V, and 240V single-phase power, delivering a full power output of 40kW. This robust setup uses a North American Charging Standard (NACS) connector and is capable of fully charging a 600-kWh Class 8 heavy-duty battery electric commercial vehicle overnight.

This solution is particularly advantageous in regions like California, where the demand for Level 3 DC fast chargers is high, often resulting in extended wait times and significant costs for installation. With CSI's 40kW EVSE and On-Board Charger Combo, fleets operating within a 300-mile range can achieve full overnight charging using standard outlets, offering a practical and cost-effective alternative to DC fast charging infrastructure.
