The separate parts of smart BMS
What smart/soft function does it have?
There are severl options for the smart BMS,which you can have different function from it.Deligreen's smart BMS has CAN/UART/FAN,and LCD control.It denpends on what protocal of your battery is.We will supply the relevant cables for the connection,UART,USB.CAN.
Every smart BMS has a bluetooth module along with the shippment,as well the USB-UART cable.
The other parts to be given according to the type you place.
The BMS output different signal according to the connector of your battery,UART,485 or CAN protocal.The easiest way to monitor the battery is connecting by bluetooth,watching on your phone.
Why deligreen BMS?
Deligreen was founded in 2010 and we have sold BMS for more than 10 years.BMS is one of our best sellers.The customers from more than 90 countries in the world have been using Deligreen's BMS,our BMSes are protecting tremendous amount of batteries in the world.It's worthy the every dollar/cent you spend on our BMS.;)
Battery Management Systems are the brains/CPU behind battery packs. They manage the output, charging,discharging and provide notifications on the status of thebattery pack. They also protect the batteries from damage.
Lithium ion is a kind of active metal,compared to lead acid battery,lithium ion is more active,which casuses over charge,over discharge problem.It needs a protection.BMS is the one that protect your battery from be damaged.
Now you are replacing the lead acid battery with lithium battery,it's worthy spending little money on protection of your batteries,which can save much money.
What is battery management system BMS?
Where to buy battery management system?
Pls go to the bottom of this page,and send us your requirement,we will contact you by email or whatsapp to recommend the BMS you need.We can ship to you freight charge included.
How does battery management system work?
The battery management system monitors battery conditions and takes actions to extend battery life. If excessive battery drain is detected, the system temporarily disables some electrical systems to protect the battery.
How to choose the BMS that I need?
You need to make sure of following
1. battery type
2. charge current
3. discharge current
4. battery pack(series,parallel)
5. Peak discharge current
Q:Which current of the PCB should i choose?
A:Take 13S 48V pack as an example: Which PCB you should choose depends on the power of your motor or the current limitation of your controller. Below 350W ,you can choose 16A.Below 500W, you can choose 18A, Below 800W, you can choose 35A,Below 1KW, you can choose 60A. Above 1200W, the same. If you are not sure, please contact us freely.
Q:What battery types do your BMS work with?
A:Our BMS can work for lithium phospate battery(Lifepo4)and NCM battery,lithium ion battery,ple let us know what your battery type before placing order.
Q:What BMS range can you supply?
A:Deligreen is a professional BMS supllier with abundant BMS range.Series from 3S-32S,Current from 10A-500A,if you need more series,pls contact us.
Q:Can I watch the battery status from my mobile phone?
A:Yes,this is waht a samrt BMS do,you can watch the status of your batteries in your APP throush bluetooth connected between phone and the BMS.
