Electric off-road vehicle Bollinger B1: information, data, prices

Bollinger B1 (2020)
Subscriptions & booklets

B ollinger Motors is making a name for itself with its minimalistically styled electric off-road vehicles attentive. The Detroit-based manufacturer has already presented the SUV B1 and the Pickup B2. One of the special features is a continuous through-loading option from the front to the rear of the vehicle. Now the Americans have patented a battery specially developed for commercial vehicles.

In 35 kilowatt-hour increments

The patent specification filed with the United States Patent and Trademark Office (USPTO) shows that the battery is modular and surrounded by a stable structure. The individual modules each have a capacity of 35 kilowatt hours - Bollinger would like to offer batteries with capacities of 35, 70, 105, 140 and 175 kilowatt hours at the market launch. All sizes should be suitable for both 300 and 700 volt operation. The batteries are surrounded by a so-called i-beam, which protects the energy storage device in the event of a side impact. In addition, cooling water channels run inside to keep the battery in the optimal temperature range.

The modular battery can be increased in 35 kilowatt hour capacity steps.

Future-proof software

The battery control software (BMS - Battery Management System) is also part of the patent. The BMS permanently monitors the voltage, current and temperature at several points on the battery pack and, if necessary, carries out appropriate controls. In addition, the BMS should be able to detect malfunctions and thus guarantee system security. According to Bollinger, the BMS is for anyone from the startNumber of battery modules and therefore also suitable for future, even larger batteries.

Bollinger positions its battery in the middle under the vehicle floor - the high-voltage battery should also be available to other manufacturers of commercial vehicles.

Batteries also for other manufacturers

According to the manufacturer, the Bollinger batteries are said to be suitable for heavy and heavy use because of their predicted high energy density and their promised high continuous output Medium-weight commercial vehicles, construction machinery and agricultural equipment are suitable. The production of the rechargeable batteries is to begin in 2021, which Bollinger will then also make available to third-party users.

In the spirit of the first generation of the Land Rover Defender: In Bollinger vehicles, every form follows a function (im Picture of pickup B2).

Form Follows Function Truck

Bollinger calls the B1 the 'most powerful sport utility truck of the world'. Every connection point, every seam and every surface of the electric off-road vehicle, which is strongly reminiscent of the old Land Rover Defender, is said to have been developed with a very specific purpose.

Removable windows, doors and roof elements

In fact, the B1 has a few distinctive features. It should be possible to remove all windows, doors and roof elements easily; latterare made of glass on request. The B1, which is 1.96 meters wide, 1.85 meters high and has a wheelbase of 3.02 meters, can accommodate up to four passengers. Or two passengers and up to 3,200 liters of cargo if the rear seats have disappeared and the front trunk is in use. In addition, the Bollinger has the practical property of being able to load bulky objects from the very front to the very back, i.e. over the entire length of 4.35 meters. Practical when there is no motor in the way and the seats are installed individually.

Bulky items can be loaded from the very front to the very back.

The is powered Electric SUV with two electric motors mounted on the axles, which drive all four wheels via a two-speed gearbox and classic drive shafts. The manufacturer specifies the system performance of the two engines with 623 hp, the torque should add up to 906 Newton meters. This should enable the angular B1 electric truck to sprint to 60 mph (96.6 km /h) in 4.5 seconds and, if necessary, reach a top speed of 161 km /h.

120 kWh for up to 322 kilometers

In the meantime, Bollinger has also released data on the B1 battery installed in the vehicle floor. The battery capacity should be 120 kilowatt hours, which should enable a range of 322 kilometers. The energy storage should be completely filled again after 75 minutes via CCS fast charging. The Bollinger B1 can of course also recuperate.

The chassis and body of the B1 are made entirely of aluminum. Equipped with batteries ready to drive, the B1 weighs just under 2.2 tonnes. The maximum payload should be almost 2.4, the maximum possible trailer load 3.4 tons. The off-road suitability is supported by the level, reinforced underbody, the ground clearance is specified as 38 centimeters. The ramp angles are 52 degrees at the front and 43 degrees at the rear, and Bollinger puts the angle of approach at 30 degrees. The B1 is equipped with off-road rubbers in the format 285 /70-17, the spring travel should be over 25 centimeters.

Sparse interior with analog instruments

It is questionable whether the Bollinger B1 can get really cozy. Thoughthe analog instruments convey a homely ambience, but otherwise the interior is pretty sparse. In addition, the Americans completely dispensed with insulation or cladding. The security and assistance systems department has also been vacant for the prototype; there isn't even a driver airbag. Air conditioning is standard on board, as is Bluetooth connectivity and six 110-volt connections for external devices. Heated seats are available in both rows on request.

Bollinger describes the current status of the B1 as a 'beta prototype'. Series production could begin in the not too distant future. Incidentally, there is no longer any talk of the four-meter-long, two-door short B1 version. The Michigan-based company puts the base price at $ 125,000. Interested parties can reserve the electric off-road vehicle in order to receive preferential delivery after the start of production of the B1.
