Re: Advantages, OK, but...
@SPI0---There are some problems as you suggest, but take a look at the following:

and

It's a debate that's been going on for a while

NOTHING COMES AS A FREE LUNCH, CAN THIS DISCUSSION INCLUDE Ethanol ? Everything seemed to work until Ethanol for small engines, but other engines as well. Phase seperation in gasoline is the root of carbuerator gumming, but will also cause problems in EFI designs.

Re: Advantages, OK, but...
@dick_freebird: I still like technology that improves a product. But---I do not like everything the government tells us we have to do----that's why we vote. Our government system is far from perfect in America, but it is still the best in the world.

When the governments say what can and can't be on the market, this becomes fanciful at best. That's the fun bit about "compliance".  When's the last time you were offered a carburated powertrain option on a passenger car? Right. Between EPA and CAFE standards-creep the manufacturers are simply forced into complex solutions and the consumer pays the tab or goes without. Yeah, you could buy used, until that pool is depleted.

 

Now there's other fun such as how these ECUs behave once sensors go bad. Like a fouled HO2S telling the ECM it's dead lean, like they all do someday. Your poor folks who drive those scooters into the ground and throw them on the piles that line the streets of Taipei - going to shell out $100 for a new sensor when the thing starts to throw black smoke and guzzle fuel, if it's still getting them down the road? Nope. More like they'll keep riding and put out worse emissions than a carb motor ever would.

 

But we are all just pawns and logic does not apply (it's just an applied coating on a deal made by, between our betters).

Re: Advantages, OK, but...
@dick-freebird: I hear you. I understand some of the additional things that this system adds to a lawn mower that might not be earth-shaking and would be more complicated.

On the other hand, people don't have to buy a lawn mower with this technology if they feel the same way as you do. However, imagine how many lawn mowers there are in the world---one or two or 1,000 may not matter, but add them all up........maybe it makes a difference in the environment.

This product makes the biggest difference in products like motor scooters----I have been in India and Shanghai and if just half of those scooters had this product---how much difference might that make?

Advantages, OK, but...
Advantages there may be, but simplicity is not one. That little 1"-on-a-side lawnmower carb becomes a collection of sensors and actuators and of course the "brain", which freaks out when any of the assembly goes bad. Probably go from magneto to electronic ignition meanwhile, so there's another set of baggage. Your push mower now gets saddled with an alternator and battery to run all that mess, and pushing it all is on you. BOM cost, that's a huge LOSE. BOM weight, I'm sure will far exceed the fractional pound involved in a pot-metal carb and a two-horned magneto.

 

But it's not about what's good, reliable or maintainable for the consumer. It's about "compliance" and it's between the manufacturer and the feds who have them by the naughty bits, machete in hand. Consumers just get to svck it.

 

Throwing all this technology at tools that get used for a couple of hours a week is just bureaucratic abuse of the citizenry for negligible benefit to anyone or the environment. Check the energy and materials input to all of that gizmosity (yeah, yeah, fuel economy bleating when the thing burns maybe 100 gallons over its service life, and you're going to improve economy 20%) and tell me that anybody (or their life-cycle-cost-of-ownership) was or will be saved.

A battery management system (BMS), in addition to many other functions, has to closely monitor voltage, current, and the temperature of battery cells and packs. Temperature measurement is important in preserving the operational characteristics of both the cells and the BMS itself, as well as optimizing the state of health (SOH) by preventing degradation.
