BMW claims its Neue Klasse electrical vehicles — the primary of which is able to go on sale later this 12 months — will likely be 20 p.c extra environment friendly than its present EVs. Why is that necessary? As a result of effectivity is the be all and finish all for electrical vehicles for the reason that energy density of batteries is far lower than the ability density of gasoline. In line with the EPA, a gallon of gasoline weighs about 6 kilos and is equal to 33.7 kWh of vitality. In contrast, a 33.7 kWh battery weighs about 357 kilos (162 kg). Which means a gasoline-powered automotive has an enormous weight benefit over a battery-powered automotive. However right here’s the factor: A traditional automotive solely converts about 20 p.c of the vitality within the gasoline it carries round into ahead movement (some extra, some much less), whereas an electrical automotive converts about 90 p.c of the vitality saved in its battery into ahead movement (additionally some  extra and a few much less). That ranges the taking part in area between typical vehicles and electrical vehicles significantly, though typical vehicles nonetheless have an total benefit in upfront price. Effectivity is what ranges the taking part in area much more.

In a press launch on February 21, 2025, BMW stated that with its new sixth-generation eDrive expertise — generally known as Gen6 — is a technological quantum leap. Enhancements embody a 30 p.c quicker charging velocity and a 30 p.c enhance in vary, with sure fashions reaching even greater figures. The Gen6 high-voltage battery idea advantages from the brand new 800-volt expertise. Gen6 will make its debut this 12 months within the Neue Klasse and subsequently be used to drive fashions throughout BMW Group’s totally electrical product vary.

The idea for the Gen6 batteries is basically new and can discover purposes in all automobile segments, as much as and together with the high-performance fashions from the BMW M division. The brand new slimmer design permits the battery to be built-in into a diffusion of various fashions, no matter automobile peak. For its sedans and sports activities vehicles, BMW will use 4695 cells which are 46 mm in diameter and 95 mm in peak. For SUVs and bigger vehicles, it can use 46120 cells with a peak of 120 mm.

The battery pack will tackle the function of a structural part within the Neue Klasse fashions, and the brand new cylindrical cells will likely be built-in instantly into the battery pack, slightly than in particular person packs which are then assembled into battery packs. The brand new cylindrical cell can have 20 p.c better vitality density than the Gen5 prismatic battery cell used beforehand. The brand new battery has additionally been designed with bi-directional charging in thoughts, which suggests automobile to load, automobile to residence, and automobile to grid operation will likely be attainable with all BMW autos that use the brand new Gen6 expertise.

“For the BMW Group, electrical mobility is the long run and a key space of progress. We’re main the best way with this drivetrain expertise. On the identical time, we’re intentionally taking a technology-open method, recognizing that mobility wants range between totally different areas of the world,” stated Dr. Joachim Put up, BMW board member liable for buying and the corporate’s provider community. “We need to supply our clients the perfect drive idea for each want. It’s attainable to do each — supply the perfect drive expertise for each want and be on the forefront of electrical mobility.”

An electrical automotive is greater than only a battery, in fact. Refined electronics are wanted to handle the movement of electrons into and out of the battery as properly. All the electronics for the Gen6 batteries are contained in what BMW calls the Vitality Grasp — a central management unit positioned on the battery that controls the high- and low-voltage energy provide and manages the info from battery. It additionally controls the ability provide for the electrical motor and automobile electrical system and ensures the secure and clever operation of the battery. BMW Group has filed a complete collection of recent patent purposes for the automobile electrical system, together with its digital fuses. Each the {hardware} and software program of the Vitality Grasp have been developed totally in-house at BMW Group, which ensures that technological developments and updates for autos that use the Gen6 expertise might be carried out independently and in actual time by way of over-the-air distant software program upgrades.

New Electrical Motor Expertise For BMW

BMW will use electrically excited synchronous (EESM) and asynchronous motor (ASM) expertise in its Gen6 platorm. In a synchronous motor, the magnetic area within the rotor is generated by windings fed with direct present slightly than everlasting magnets. On this means, the energy of the rotor’s magnetic area might be optimally adjusted to the prevailing load circumstances. This ends in each glorious ranges of effectivity in most driving conditions and fixed energy output at excessive rotational speeds. The synchronous motor will likely be positioned above the rear axle and have a compact housing incorporating the electrical drive unit, energy electronics, and transmission. Simply the design of the rotor alone resulted in ten new patent purposes. The inverter now options 800-volt expertise together with silicon carbide (SiC) semiconductors to spice up effectivity and is totally built-in into the housing of the electrical motor.

The Gen6 powertrain employs a second, extra electrical motor expertise within the type of the asynchronous motor (ASM). Right here, as an alternative of being generated by everlasting magnets (PSM) or electrical excitation (EESM), the rotor’s magnetic area is induced by the stator. On one of these motor, the rotor takes the type of a steel cage. The asynchronous motor affords the benefit of a extra compact design and superior price effectivity. The ASM motor variants will energy the entrance wheels of Neue Klasse vehicles with xDrive.

In line with BMW Weblog, the corporate stated on the introduction of the Gen 6 expertise this week that its future electrical vehicles would be capable to drive no less than 373 miles (600 kilometers) on a full cost, with some fashions able to as much as 570 miles (900 km) between chargers. As well as, the brand new 800-volt structure will allow 30 p.c quicker charging, so not solely will the vehicles be capable to drive additional, they are going to spend much less time charging when the necessity arises. Say goodbye (and good riddance) to vary nervousness! As well as, the corporate stated a few of its future electrical vehicles may include three and even 4 electrical motors.

BMW has not stated particularly which future fashions will get which mixture of motors or obtain the promised vary figures, however it’s clear the Neue Klasse autos and the Gen6 battery expertise will likely be a quantum leap ahead for the corporate and for the EV revolution. Of all of the German producers, BMW has loved essentially the most gross sales success with its electrical automotive choices, primarily as a result of it supply drivers the identical degree of consolation and efficiency they’re used to. Give the folks what they need and loads of it is a properly worn gross sales technique — as a result of it really works. The underside line is all of the technical geewizardry on the planet is value nothing if folks don’t purchase your merchandise. BMW appears to know this fairly properly.
