Up to now, we have dismantled and fully tested actual specs of 6 other boards, discovering that actual vs claimed specs is a world apart. Advertising misleading power ratings is just the tip of the iceberg. We have seen quite a few components that are subject to mechanical or electrical stress during “normal” operation that are outside of safe specs.
For example, one of the major brands we’ve tested sends 10.5 A of re-gen current directly into cells rated for 1.5A normal and 4A fast charging.
Prior experience shows the market is unreceptive or unwilling to hear such info, especially from a company who has yet to deliver its first production units.
Any suggestions on how to harness our powers for good?
On some Chinese brands, it is quite obvious that the numbers can’t be true, but some scientific measures to show how far they are away from the real world would be really nice.
I am not a specialist but isn’t the fast charging of max 4A only important when you do that continuously. I guess short bursts with higher amps (like our braking) will be no issue. I think that is the same like discharge bursts. But maybe I am also completely wrong. Couldn’t find any information somewhere because normally the manufacturer doesn’t expect that it will be used for regenerative braking.
But who knows how scientific his article is. I think we shouldn’t worry. And I feel better with a setup that allows my to brake harder in times of crisis where I don’t use the full brake power all the time instead of a brake that might protect the battery but not me.
