Apple today filed a patent related to electric vehicle charging, another sure sign that the company is working on its own Apple Car.
The patent, published today and spotted by ComoHow, was filed by Apple in March and is titled “Modular Vehicle Charging Systems.”
The summary says:
Systems and methods for charging modular vehicles are described. For example, one method may include connecting a vehicle to a charger using a charging plug interface that includes a first pair of leads connected to AC terminals of an AC-to-DC converter on board the vehicle and a second pair of leads connected to the terminals of a vehicle battery; and charging the vehicle battery via direct current flowing in the second pair of leads simultaneously with charging the battery via alternating current flowing in the first pair of leads to power the on-board AC-to-DC converter .
This specifically relates to the on-board charger that is included in electric vehicles, necessary to reduce the amount of charging infrastructure needed outside the car. By having a good OBC, some vehicles can accept AC power directly from the mains. Faster DC charging is only available at dedicated charging stations in certain locations.
The patent says the technology at stake “can be used to provide a premium home charging experience for an electric vehicle” and could reduce charging times by including an “integrated AC-to-DC converter” and an AC-to-DC converter. from an external charger. that can be installed in the house. The patent also allows for a high-capacity battery in the external charger that can provide even faster charging when it has been “pre-charged with efficient means” such as a solar cell. He follows:
Users who want more power and faster charging times at home (eg 10-20 kW) and have a power infrastructure that includes an AC breaker panel that supports it, can also install a stand-alone charger at the home (for example, wall-mounted) that is configured to convert additional power (for example, an additional 13 kW) to charge a vehicle battery. The external charger can allow the vehicle battery to be charged by AC and DC power simultaneously. For example, the stand-alone charger can be plugged into one or more wall outlets that provide AC power (for example, 240 volts AC at 60 Hz). For example, a charging plug interface (eg, including a cable) on the external charger can route AC power to the vehicle’s integrated charger (eg, providing 7 kW of charging power), while which at the same time uses the AC to DC. External charger converter output to supply power (e.g. additional 13 kW) to the vehicle as DC through the charging socket interface. Such a configuration can provide the advantage of using the OBC (for example, a 7 kW charger) that the vehicle driver has already purchased, and reduce the size and cost of the external charger used to achieve a given charge.
You can read the full, incredibly dense patent here. The patent, filed just this year, has yet to be granted to Apple.
It’s no secret that Apple is still working on an Apple Car of some description, with leaks and rumors pointing to an expected 2025 release date. In the meantime, the closest thing we have to Apple Car is a major new update to CarPlay. who was teased. at WWDC 2022 for the best future Apple iPhones.
