The Chevrolet S-10 Electric was an American electric-powered vehicle built by Chevrolet. It was introduced in 1997, updated in 1998, and then discontinued. It was an OEM BEV variant of Chevrolet's S-10 pickup truck. The S-10 Electric was solely powered by electricity, and was marketed primarily to utility fleet customers.
General Motors started with a regular-cab, short-box (6-inch (15 cm) bed) S-10 pickup, with a base-level trim package plus a half-tonneau cover. In place of a typical inline four cylinder or V-6 internal combustion engine, the Electric S-10 EV was equipped with an 85-kilowatt (114 hp) three-phase, liquid-cooled AC induction motor, based on GM's EV1 electric coupe. The EV1 had a 100 kW motor; GM reduced the S-10EV's motor because of the additional weight and drag of the truck so as not to overstress the batteries.
Other than the reduced motor size, most of the EV1 power electronics were carried over directly to the S-10 EV, which mandated that the Electric S-10 use a front-wheel-drive configuration, unlike the rear-wheel-drive setup of the standard S-10, and in the competing Ford Ranger EV.
Similar to the Gen 1 EV1's, there were lead acid battery and nickel–metal hydride battery options. The 1997 Chevrolet S-10 EV used a lead acid battery pack. Manufactured by Delco Electronics, the 1,400 lb (635 kg) pack consisted of 27 batteries, with one being designated as an "auxiliary" cell. These reportedly offered 16.2 kilowatt-hours for propulsion. In 1998, an Ovonic nickel–metal hydride battery (NiMH) pack was also available; these batteries were lighter (1,043 lb (473 kg)) and had a combined 29 kilowatt-hours of storage for a longer range. NiMH also has longer life but costs more than the lead acid option. The battery pack was located between the frame rails, beneath the pickup bed. On all battery types, a passive battery monitoring and management system was used; this meant that excess energy was wasted from cells with a higher charge, while the remainder of the cells reach the same state of charge.
