mislabeled BMS ! what to do?

Hi I'm repairing a bike for a friend. He has given me all of the components including this BMS which seems to be mislabeled. Normally i would expect to see connections for B- (battery -ve), C- (charger -ve) & P- (controller -ve). Sometimes there is only B- and -ve. On this board there are three sold...

Re: How much did you save driving your electric car last year?

I used to have a 55mpg diesel. If anyone here swapped a 30mpg fossil burner for their EV then they would win i think. I do 20k miles too tho.

How much did you save driving your electric car last year?

Hi i saved £1800* (2400$) last year by driving a leaf24 instead of a diesel ford focus.

Is this the highest or can anyone top that?

*My number includes: taxes, fuel, depreciation, electric but not insurance or mainance. I assumed they were the same for both cars.

Re: recharging in the field - the ultimate!

Think about it this way john. The bike i ride is illegal on UK roads and look it! I have very little free time nowadays (kids) so ild rather not waste time and energy on the stuff i don't like (roads) and instead focus on the fun stuff. I see your point and in the past i would have agreed with you. ...

Re: recharging in the field - the ultimate!

I charge my bike in the back garden in case it catchs fire. The batteries on my rucksac are in a biscuit tin and i have thick packing material to protect me. I ride motocross and have fallen off about 10 times this month. All low speed tho 'drop the bike' type stuff.
....But your right.

Re: recharging in the field - the ultimate!

To do this right you need an electric car. Because you don't need to leave the engine running and the cars battery will last for days!

recharging in the field - the ultimate!

How about this idea? You drive your car to the trails with your electric bike in it. You ride round for an hour and flattern your first battery. Then you swap over to your second battery in you back pack and ride back to your car. You then plug your first battery and charger into an inverter run off...

Re: Opportunity Charging in the UK/Belgium/Holland

So you can use the all the ev charging network if you have the right cards and aps. Tho your probably not supposed to use adaptors on outdoor chargers incase it rains.
some ev drivers might get irate and complain tho.

You can also buy j1772 adaptor sometimes on ebay for plugging older EVs into type 2 sockets. It will give you a 3 pin plug

Re: ping battery charger big bang

it could have shorted at the plug. if you are bending the wires. they can break off and short. this will short and could blow the charger.

Re: Solar Electric

i think its proof of concept. putting weight in the wheels is a bad idea imo. but you might be able to get 40W(peak) out of the wheels. practically would only be 20W or less tho. sun only shines 8 hours a day so it would take 3 days to fully charge a large battery. small 200w ebike could get charged...
