Jomar Pichardo, 31, who’s responsible for keeping the city’s fleet of EMS ambulances running 24 hours a day, has saved the department more than $700,000 by engineering ways to refurbish ambulance batteries and car parts that the city would normally toss away and repurchase.

In his three years with the FDNY working at the department’s Long Island City garage, Pichardo created a battery charging station that can charge 10 batteries at once. He’s also come up with a “restoration room” where ambulance parts can be cleaned and refurbished to be used again. The restoration room has led to an estimated $645,000 in savings to the FDNY, officials said.

Pichardo is also the FDNY’s MacGyver, turning an old tank found in the back of the garage into a heated cleaning unit — another $60,000 save for the department.

“We first used a power washer, but that didn’t work very well, so we improvised,” he said. “The heated unit cleans it a lot better.”

“Protecting life and property in our city not only requires brave first responders, it also requires many dedicated and knowledgeable civilian employees like Jomar,” Nigro said.

Pichardo created the charging station after he went to the FDNY’s parts counter and learned how many ambulance batteries were being tossed.

“We would go through 20 batteries a day,” Pichardo said. “I got a couple of ideas, so I just started setting things up and expanding the methods. Now for the price of two batteries, we can charge 10 batteries.”

Pichardo also devised a way to replace computer parts on a circuit board that can be found on every ambulance.
