Description
*Product Advantages:
It supports 500A continuous current output, and the peak current can reach 2000A. It is not easy to be heated and damaged. If damaged, the main control will not be affected. You only need to replace the relay to reduce maintenance costs. Current relay power consumption: 250mA.
The relay is a main circuit switch. You can choose different currents, but the maximum current does not exceed 500A. It is recommended that the working power consumption be less than 500mA. BMS only provides 12V control voltage to control the introduction of relay.
1. BMS built-in BT module can be used to view battery parameters on the phone( Android only, IOS is under development ).
*Mobile APP not available for BMS more than 32S and Master-slave design.
2. You can develop your own application system according to your own needs. We can provide BMS interface communication protocol.
3. The main protection functions of BMS are: overcharge protection, overdischarge protection, overcurrent protection, balance protection, short circuit protection, BMS low voltage sleep, NTC temperature control protection, etc.4. The application can adjust hardware and software parameters and support Li ion, LiFePO4, LTO batteries.5. It can be compatible with 3S-32S lithium battery pack. The length of the balanced cable is about 800mm. There are marks on each cable such as B-, B1+, B2+……B16+, B+. This is a very convenient design for welding cables.
6. Static balance: setting the battery voltage difference between 0.02V-0.05V, it will automatically turn on the balance function.
7. Application: large vehicle starting power, solar energy storage, engineering vehicle, low speed four wheeled vehicle, RV or any other device you want to place.
8. The protection parameter settings and modified:
Charge and discharge high temperature and low temperature, battery pack overvoltage and undervoltage, unit cell overvoltage and undervoltage, short circuit and differential pressure value, balance voltage can be modified. It can also reset and restore factory settings.
Warm tips:
* BMS can handle at most 240S battery pack with master-slave design. Battery above 32S is recommend to consider this master-slave design.Kindly contact us for more info.
*We can also provide Charger that CAN communicate with BMS for charging,For more info. kindly contact us directly.
This is our real project for 110S 352V Solar Energy Storage
This client just want save money choose two package , one is 55S, but it is not good for package or any repair . So if you need high voltage bms system . Just contact us .
If one battery is packed in 16S, and 10 pack in total, it’s 160S 512V battery pack.
Therefore, you need 10 pcs slave bms board and other accessories.
If it’s 64S system,consider two 32S batteries pack in series, the selling price is the same as the 36S. So just select the 36S slave board will be fine.
Details of Relay smart BMS:
Suggestion
Below 200A choose 2 Relay is enough
above 200A choose 3pcs relay
if used on like Heavy Truck start up. choose 4pcs relay
Sku details:
3-4S BMS : include 1*3-4S BMS with harness + 1*Hall
6-8S BMS : include 1*6-8S BMS with harness + 1*Hall
10-24S BMS : include 1*10-24S BMS with harness + 1*Hall
25-32S BMS : include 1*25-32S BMS with harness + 1*Hall
For high discharge current (250A and above), and string 25S and above , we recommend using pre-resistance and pre-charging relay to work together
If used on same port(charging and discharging share the same port), we recommend using Anti-reverse diode to work together.
