Complete Coach Works (CCW), an innovator in heavy-duty electric transportation, announced that they now offer an optional 466 kWh onboard energy storage system.

CCW increased its Zero Emission Propulsion System (ZEPS) battery pack in order to increase power and range. Currently, there are more than 50 ZEPS buses deployed in service across the nation with more than three million revenue miles. These deployments have been proven to perform successfully in all types of weather conditions, according to CCW.

IndyGo and Indy Airport operate 30 ZEPS buses for its day-to-day operations. The City of McAllen Transit Department utilizes two ZEPS buses to operate out of the city’s International Transit Terminal where passengers can connect for several international, national, regional and intercity destinations.

“We were able to keep the battery pack light, which improves vehicle reliability and efficiency," said Brad Carson, CCW’s Director of Sales and Marketing. "Our company is committed to providing the transit industry with the most advanced technology and this upgrade will give agencies the extended range they need on a single charge.”

Using advanced lithium-ion batteries and liquid-cooled all-electric drive systems, the performance of ZEPS delivers a significantly longer operating range while maintaining battery life. Other features include a permanent magnet synchronous motor that provides maximum torque at the start and a smooth acceleration profile.

The ZEPS saga started as an option to provide customers a clean, cost-effective, and viable alternative to fossil fuel. Working with its sister company Transit Sales International, CCW developed its own system by taking an existing low-floor transit bus and rebuilt it as a battery-electric bus. The resulting ZEPS bus offers economical options to bus operators looking to start an electric bus operation. Operators can opt to purchase newly refurbished buses from CCW’s inventory or have their existing fleet converted to all-electric.
