Like the GLB, the EQB is based on the floor plate of the Mercedes-Benz compact car, which includes the A-Class and CLA, but is not. That’s because it’s 10 inches longer, and even different because of the battery built into the floor. The battery is housed in a frame made of extruded sections that act as underground transverse members.
The EQB lithium-ion battery consists of five units, with a maximum voltage of 420V and a rated power capacity of 66.5 kWh with a rated capacity of approximately 190 hectares. An aluminum casing protects, in addition to the bodywork itself, the 469-pound battery, which is also equipped with liquid cooling. Mercedes has a warranty of 8 years and 160,000 km.
Unfortunately, the car receives a maximum of 11 kilowatts of alternating current (AC) charge, so it would take six hours from a public charging station or home-installed wall charger to fully charge the car from 10 percent. More than 30 hours of normal outlet. It is capable of 100 kW of direct current charging, so 32 minutes is enough for a 10-80% charge using a CCS conductor.
Mercedes offers a number of features in addition to general charging, including purchasing electricity from renewable energies, reduced use of Ionity chargers, and access to hundreds of thousands of poles with a single payment app.
The EQB is currently available in Europe in two versions, the 300 with 168 kW (228 hp) and the 350 with 215 kW (292 hp). The maximum torque of the first is 390 Nm, while the last version provides 520 Nm. Both have front and rear engines, that is, they are four-wheel drive and have the same WLTP range of 395-419 km. Dual-wheel drive and longer-range versions will also come later.
The drive chain uses an asynchronous synchronous motor on the front shaft and a fixed excitation motor at the rear. At the front, the electric motor forms a unit with a differential, a fixed-speed transmission (unlike EQS, there is only acceleration in reverse), a cooling system and power electronics.
Essentially, the rear engine cranks the vehicle to reduce fuel consumption, with the front engine engaged if necessary. The torque distribution is electronically controlled and can even simulate a central differential lock. When idling, both engines switch to starting the generator and co-charging the battery. The weaker version accelerates from a standing state to 100 km / h in 8 seconds, and the more powerful version in 6.2 seconds. Their maximum speed is 160 km / h.
The EQB has suspension with steel springs as standard, and MacPherson has four swingarm solutions in the rear. It can also be equipped with an adaptive damping system at an additional cost.
A number of driving assistance systems can assist the EQB driver, including Active Lane Keeping Assist and Active Brake Assist, which are standard. But it can also include the cornering maneuver function, the emergency lane function, the exit warning function, the pedestrian detection warning, the turn steering assist and the blind spot display.
