Re: [PSES] Safety for e-scooters, e-bikes

[John E Allen]

Comments from purely subjective personal experience:

*   True for their “professional” grade power tools
*   Maybe less so for their “consumer/domestic” grade products (especially 
gardening power tools where I have had several failures)? 
*   OTOH the resulting warrantee service has generally been very good.

Dan,

 

It appears to me that Bosch's products are well designed and made in general 
and agree to have high confidence in their products.

Doug/Scott,

 

My wife’s e-bike has a Bosch motor and battery and seems to be well made and 
certified so I am comfortable storing and charging it in my garage.  Included a 
picture of the label with agency marks, sorry it is a little blurry.

 

So I think there are definitely safety schemes available, but as with 
everything, quality may vary from vendor to vendor.  I would trust Bosch over a 
vendor I never heard of and the Bosch motor and battery certainly played a 
large role in picking which e-bike to purchase.

Dear Doug,

 

I learned that China prohibits carrying e-scooters and e-bikes to their houses 
and even entering the lifts of the building for storage/charging.  Since the 
battery capacity is much bigger than the li-ion battery using in normal 
portable devices, the battery and the charger must comply with rigid safety 
requirements.  Do not recommend buying unknown brand products in this type of 
goods.

 

Regards,

 

Scott

All,

 

My Friday question is about storage/charging of e-scooters and e-bikes. It 
seems that these days more and more people are using these devices and fire 
safety is a growing concern. It seems my news feed has a new instance every few 
days.  Some of these cases are very tragic outcomes, in that the owner brings 
these devices just inside the door to their apartment for overnight charging.  
Of course, if there is a lithium fire, it is rather violent and blocks the exit 
for the occupants.

 

I am not very familiar with which safety standards are available in North 
America and Europe, and do they have requirements to address such concerns in 
the user documentation?  I do know that some building owners are taking matters 
into their own hands and requiring these devices be charged outdoors; which may 
have varying success in mitigating building fires.  In any case, many e-scooter 
owners are probably not very keen on leaving their property where it can be 
easily stolen.

 

Thoughts?

That is very interesting, and there's something to be said about timing.
