BMW claims its New class Electric Cars — the primary of which is able to go on sale later this 12 months — might be 20 p.c extra environment friendly than its current EVs. Why is that vital? As a result of efficiency is the be all and finish all for electrical automobiles because the 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 power. Against this, a 33.7 kWh battery weighs about 357 kilos (162 kg). Meaning a gasoline-powered automotive has an enormous weight benefit over a battery-powered automotive. However right here’s the factor: A standard automotive solely converts about 20 p.c of the power 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 power saved in its battery into ahead movement (additionally some  extra and a few much less). That ranges the enjoying subject between typical automobiles and electrical automobiles significantly, despite the fact that typical automobiles nonetheless have an general benefit in upfront price. Effectivity is what ranges the enjoying subject much more.

In a press release on February 21, 2025, BMW mentioned that with its new sixth-generation eDrive expertise — often called Gen6 — is a technological quantum leap. Enhancements embody a 30 p.c quicker charging pace and a 30 p.c enhance in vary, with sure fashions reaching even increased 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 functions 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 top. For its sedans and sports activities automobiles, BMW will use 4695 cells which might be 46 mm in diameter and 95 mm in top. For SUVs and bigger automobiles, it would use 46120 cells with a top of 120 mm.

The battery pack will tackle the position of a structural element within the Neue Klasse fashions, and the brand new cylindrical cells might be built-in instantly into the battery pack, somewhat than in particular person packs which might be then assembled into battery packs. The brand new cylindrical cell could have 20 p.c higher power 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 house, and automobile to grid operation might be doable with all BMW autos that use the brand new Gen6 expertise.

“For the BMW Group, electric mobility is the future and a key area of growth. We are leading the way with this drivetrain technology. At the same time, we are deliberately taking a technology-open approach, recognizing that mobility needs vary between different regions of the world,” mentioned Dr. Joachim Put up, BMW board member chargeable for buying and the corporate’s provider community. “We want to offer our customers the best drive concept for every need. It is possible to do both — offer the best drive technology for every need and be at the forefront of electric mobility.”

An electrical automotive is greater than only a battery, in fact. Subtle electronics are wanted to handle the circulate of electrons into and out of the battery as nicely. All the electronics for the Gen6 batteries are contained in what BMW calls the Power 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 an entire collection of latest patent functions for the automobile electrical system, together with its digital fuses. Each the {hardware} and software program of the Power 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 applied independently and in actual time by way of over-the-air distant software program upgrades.

New Electrical Motor Know-how For BMW

BMW will use electrically excited synchronous (EESM) and asynchronous motor (ASM) expertise in its Gen6 platorm. In a synchronous motor, the magnetic subject within the rotor is generated by windings fed with direct present somewhat than everlasting magnets. On this means, the power of the rotor’s magnetic subject might be optimally adjusted to the prevailing load circumstances. This ends in each wonderful ranges of effectivity in most driving conditions and fixed energy output at excessive rotational speeds. The synchronous motor might 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 functions. 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, further electrical motor expertise within the type of the asynchronous motor (ASM). Right here, as a substitute of being generated by everlasting magnets (PSM) or electrical excitation (EESM), the rotor’s magnetic subject is induced by the stator. On this kind of 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 automobiles with xDrive.

In line with BMW blogthe corporate mentioned on the introduction of the Gen 6 expertise this week that its future electrical automobiles would be capable to drive at the least 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 automobiles 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 mentioned a few of its future electrical automobiles might include three or even four electric motors.

BMW has not mentioned 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 might 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 sales success with its electrical automotive choices, primarily as a result of it provide drivers the identical degree of consolation and efficiency they’re used to. Give the folks what they need and loads of it is a nicely worn gross sales technique — as a result of it really works. The underside line is all of the technical geewizardry on the earth is price nothing if folks don’t purchase your merchandise. BMW appears to know this fairly nicely.
