Comment Re:"Advanced battery technology" is a flashlight b (Score 1) 133

I see that the Tesla battery pack weighs 1,200 pounds. Reducing weight greatly improves efficiency, handling, braking, and acceleration, meaning lighter weight is all around better. It seems a bit wasteful of weight and materials to have 7,000 metal casings around 7,000 tiny batteries, connected with thousands of connections, rather far fewer larger cells. I'm surprised they don't use perhaps 24 or 100 larger cells instead, thereby eliminating thousands of unnecessary casings and connections.

There are a number of reasons.
1. 18650 cells are the cheapest per kWh, significantly so.
2. The smaller cell size helps with thermal management. It's easier to deal with the heat from using the batteries the smaller they are. There have been problems with airlines that use larger cells with them catching fire.
3. Power capability is actually higher with smaller cells. For a car with the acceleration of a Model-S, this is important.
4. Due to the amount of R&D into the cell, which is the most common LiIon cell in the world, weight and volume wise it's at least as energy dense as anything else, extra casing or not.
5. The connections aren't actually that big of a deal, most of the batteries are simply end-to-end.

Unfortunately, it's not true they just say "no". They say "no" to big stumbling blocks, not everything. In fact, the record shows plenty of laws passed. Somewhere upwards of 95%. But on big issue items, where the two parties have fundamentally different approaches/solutions, there is nothing moved forward. As it should be.

One other datapoint... Silicon Labs has a Lightning-to-Audio converter (CP2614) available. it's $3.39 in 100K quantities. You still need an amplifier on it, as well as some power supply filtering and protection. It's still a $5-$6 electrical solution, on which a package needs to be placed, then assembly costs, etc. It's not cheap to do a Lightning-to-analog conversion adapter, not cheap at all.

Nope, built in volume (100K/yr) in a factory in Zhuhai. Using a TI amplifier ($1.20/100K pieces), AKM DAC ($1.00 for a good quality unit, 100K pricing). Regulators ($0.70 - need 3.3V and 1.8V, LDOs are cheap but not that cheap), passives (another $0.40, driven mainly by caps), connectors, mechanicals (squirt a part, shoot a little paint, you're at $0.50 in 250K pricing). It's not cheap - which is why there is a STRONG market for counterfeit IAP2 chips, and many who don't pay the appropriate licensing fees, and many who use raw plastic finish (screw flow and knit lines), improper connectors (fake Lightning connectors with questionable tolerancing), etc.

This isn't just "an adapter" - it also would need to have a full DAC and amplifier inside, as well as a power supply. So it's more than the simple connector/wiring adapters you're thinking of.

Most of this is in the MFi manufacturing (Made For iPhone) program, and you can only get details if you're an audited and accepted factory to build MFi products (I've done several MFi products in the last few years, I've been through the Apple approval grinder more than once). But Apple doesn't let you build products that play with non-iOS or even obsolete iOS devices and still get the MFi (and thus, Lightning) licensing. Does it run afoul of anti-trust laws? Only if someone was to take it to court and push it through - which would be a very long, very expensive process. And there a few manufacturers out there making MFi-like cables for Android.

You can thank Apple for that. If you want the "made for iPhone" logo on your box, then you have to include an IAP2 chip and CANNOT include functionality to support other devices (part of the deal). So a company can do a universal iPhone AND Android controller (it's trivial), but Apple will not license you the IAP2 chip, and thus you cannot claim it is "made for iPhone". It's their way - or no way.
