The official  introduces the new Mercedes-Benz  A-Class E-CELL as its second electric car built in series-production conditions, with following the B-Class F-CELL fuel-cell car,Following the B-Class F-CELL fuel-cell car, The five-seater with battery-powered electric drive meets all the requirements for a family car for everyday use.

The electric drive of the Mercedes-Benz A-Class E-CELL is a permanent-field synchronous unit developing a peak output of 70 kW (95 hp), a continuous power rating of 50 kW (68 hp) and a high maximum torque of 290 Nm, as expected for an electric drive, available right from the first revolution. This makes the A-Class E-CELL an outstandingly assured and dynamic performer on the road, taking just 5.5 seconds to accelerate from zero to 60 km/h. A kick-down function is used to deliver maximum acceleration, according to the current charge level and battery temperature. Maximum speed is electronically set at 150 km/h.

The energy storage units are two high-performance lithium-ion batteries based on high-voltage technology. The advantages of lithium-ion batteries include their compact dimensions and significantly higher efficiency in comparison with nickel-metal-hydride (NiMH) batteries. They offer 30 percent more energy density than NiMH technology, and 50 percent more power density. Other benefits include high charging efficiency and a long service life. The combined energy capacity of the two lithium-ion batteries is a total of 36 kWh. With fully charged batteries, the Mercedes A-Class E-CELL has a range of over 200 kilometres (NEDC).

The batteries of the Mercedes-Benz A-Class E-CELL can be either replenished at public charging points or plugged into an ordinary household power socket. A range of charging options are available, including single-phase 230-volt sockets, three-phase sockets in a household wall-box, and public recharging points. Using a single-phase 230-volt network, it takes around eight hours’ charging time to accumulate the energy required for a range of 100 km (NEDC). This time is reduced to just three hours in the case of charging from a wall-box or at a roadside recharging point.

The new A-Class E-CELL also has plenty to offer in terms of Mercedes-quality equipment. Standard highlights in the premium quality “AVANTGARDE” version of this innovative electric car include bi-xenon headlamps, COMAND APS, an active park assist for automatic parking and the THERMOTRONIC automatic climate control system. A special additional function is the ability to preset the interior climate during charging, i.e. raising or lowering the compartment temperature according to the weather conditions. The car also has a comprehensive range of safety features, including rear window bags and sidebags, and sophisticated seating and lighting packages.

Mercedes-Benz applies the same high safety standards in the A-Class E-CELL as in all its other series-produced vehicles. The electric drive system has demonstrated readiness for series production in extensive practical testing programs. Key components have also been proven in Mercedes-Benz fuel-cell vehicles, for example, allowing Mercedes engineers to draw on the experience gained from more than 4.5 million test kilometres in everyday use. The integrated safety concept reflects the specific characteristics of the vehicle’s innovative drive system. The lithium-ion batteries and high-voltage system of the A-Class E-CELL are protected with a comprehensive safety concept.
