Tesla Model Y With BYD Blade Battery Demonstrates Rapid Charging Despite Small Battery Pack Size

Tesla has started deliveries of a new Model Y variant in Germany with batteries supplied by BYD. The new Model Y, despite sporting the smallest battery pack size of all Model Y variants, is nonetheless showing impressive charging speed thanks to the BYD Blade batteries' ability to maintain peak charging speeds for the majority of the charging curve.

According to news reports by Teslamag, since the beginning of this month, Tesla has reportedly started producing a new Model Y variant at Giga Berlin. The information was confirmed by local Tesla enthusiasts who took a tour of the Berlin plant.

Participants of the tour noticed a fourth Giga Press at work at the plant and got confirmation from Tesla employees that the plant has started production of a new Model Y variant. The new Model Y, like the Giga Texas Model Y All-Wheel-Drive, uses both front and rear casting, however, the Giga Berlin Model Y comes with some important differences.

The made-in-Germany Model Y is only Rear-Wheel-Drive and is the third variant of the vehicle to be built at Giga Berlin, following the Performance and Long Range variants which began production last year.

However, the biggest difference from that of the Giga Texas Model Y is that the new Model Y, according to information shared with German regulators last year, will be using batteries supplied by Tesla’s Chinese competitor BYD.

The new BYD battery Rear-Wheel-Drive Model Y has a smaller sized pack and shorter range than both the Giga Texas AWD Model Y and the Giga Shanghai Rear-Wheel-Drive Model Y. The Giga Shanghai Model Y uses 62KWh lithium-iron-phosphate (LFP) packs from CATL and has a 244-mile EPA-estimated range.

The exact battery pack size of the new Giga Berlin Model Y is not yet known however, it’s estimated to be around 56-58KWh LFP battery pack. This makes the new Giga Berlin Model Y, the variant of the all-electric crossover with the smallest battery.

According to Tesla’s online configurator, this new Model Y variant has a 273-mile WLTP estimated range. However, the WLTP range gets subtracted by around 15% to 20% when converting to the EPA range meaning the vehicle has close to 225 miles range

The new Model Y’s 225-mile range is uncharacteristic of Tesla which even back in 2008 with the original Roadster maintained an EPA-estimated range of over 240 miles. Despite the range, producing this variant is still considered a success especially considering that it has a 45,000 euro starting price which is 10,000 euros cheaper than the Model Y Long Range variant.

Considering that only some people need a 250-plus mile range EV and the ubiquity of charging infrastructure in Europe, this vehicle makes a lot of sense for certain buyers.

Adding to the importance of the Rear-Wheel- Drive Model Y, only a couple of weeks after the news of the start of production, Tesla delivered the first BYD battery-equipped Model Ys to customers in Germany.

According to data posted by the new owners on the TFF forum and seen by CSEVTech, the Rear-Wheel-Drive Model Y has some impressive charging capabilities despite its relatively small battery pack.

The new vehicle has a 170KW peak charging capacity. Although this is below other Model Y variants which have a peak charging rate as high as 250KWh, the smaller battery pack coupled with the vehicle’s capability to maintain the 170KW peak charging for a significant stretch of the charging curve, the new Rear-Wheel-Drive Model Y still comes with charging speeds.

The Vehicle can go from an 11% state of charge to 71% in only 15 minutes and is able to maintain the 170KW peak charging speed all the way until the vehicle reaches a 50% state of charge.

CSEVTech which compared the BYD-powered Model Y’s charging speed with that of the Model Y with CATL LFP battery says that the latter “has a similar initial charging performance, but the power will quickly drop afterward, and at 50% it can only maintain around 110kW.”

This suggests the BYD Blade Model Y despite its small battery pack still has some tricks up its sleeve which give it an impressive charging capability. Currently, Tesla is just starting delivery of the Rear-wheel-Drive Model Y Germany and, we’ll keep you posted once we receive more information regarding the new vehicle.
