‘Vigor+’ Battery Pack Is Designed as Drop-In Replacement for NiMH Units
Indiana’s EnerDel, citing a supply agreement, is stepping up its promotion of its Vigor+ brand lithium ion battery packs as a drop-in replacement for nickel metal hydride batteries on hybrid buses and other heavy duty electric drive vehicles.
The 20-kilowatt-hour, PP320-689-LP Vigor+ is described as a low-profile ESS, for energy storage system. It is designed for single-pack operation in hybrid buses, and is scalable for higher-energy applications.
The low-profile lithium ion ESS “offers an increased energy density of more than 300%, a lighter weight, and a performance, fueling and price-point advantage over most of its NiMH counterparts,” EnerDel CEO Michael Canada says in a release.
Road-testing of EnerDel’s ESS for diesel-hybrid buses began nearly one year ago, the company says, citing more than 50,000 miles of “failure-free” passenger service at a major transit authority in North America.
“Additional early production systems are successfully operating in regular passenger service in tropical climates as well, demonstrating the air-cooled thermal management design across various atmospheric profiles,” EnerDel says.

“The new low profile design is a strong option for Original Equipment Manufacturers of heavy-duty vehicles seeking air-cooled hybrid packs or scalable solutions for all-electric programs,” EnerDel transportation Tomasz Poznar says in the PP320-689-LP Vigor+ announcement.
“It is also an excellent aftermarket solution for transit authorities under pressure to replace aging NiMH batteries in order to lower maintenance costs and enhance fuel economy,” he said.
Seattle’s King County Metro is a major EnerDel NiMH battery replacement customer (F&F, April 14).
