Deploying WAV Energy Mobile Chargers

ACOMPANY is preparing to launch a micro-transit service in 4 weeks using a fleet of 14 electric buses, each equipped with 90 kWh battery packs. However, the company faces a critical infrastructure bottleneck: only two 90 kWh chargers are currently available, and the local utility has quoted a $2 million upgrade fee with a 2-year lead time to expand power capacity. Each additional charger would cost $80,000.

To meet the launch timeline and avoid costly delays, ACOMPANY must find a scalable, cost-effective charging solution that works within it’s existing power constraints. WAV Energy proposes a fleet of 4 Mobile EV Chargers, each equipped with a 184 kWh battery pack, as the ideal solution.

• Charging Capacity: Only 2 chargers are available for 14 buses
• Utility Constraints: $2M infrastructure upgrade + 2-year delay
• Operational Challenge: Nighttime bus repositioning for charging is inefficient
• Launch Deadline: 4 weeks

Deploy 4 Mobile EV Chargers from WAV Energy, each with a 184 kWh battery pack, to supplement the existing charging infrastructure.

1. Daytime Charging: Mobile Chargers are recharged using the existing two Level 3 chargers.
2. Nighttime Deployment: Once charged, Mobile Chargers are moved to bus parking locations.
3. Bus Charging: Buses are charged in place, minimizing repositioning and labor.
4. Cycle Repeat: After buses depart for service, Mobile Chargers return for recharging.

Benefit and Impact

Meets Launch Timeline 

Enables full fleet readiness in 4 weeks

Avoids $2M Infrastructure Cost 

Saves millions in capital expenditure

Minimizes Bus Movement

Reduces labor, wear-and-tear, and operational complexity

Flexible & Scalable

Can be redeployed or expanded as fleet grows

Low Investment

< $500,000 for 4 units vs. multi-million infrastructure

Grid-Friendly

Uses existing chargers, avoids peak demand spikes

Financial  and Time Comparison

Utility Upgrade + Chargers - $2,000,000 + $560,000 ~2 years

WAV Mobile Chargers (4 units) - <$500,000 <4 weeks

This solution aligns with ACOMPANY’s goals:

• Rapid deployment for service launch
• Sustainable operations using battery-powered mobile infrastructure
• Cost-effective scalability for future fleet expansion
