- 48V15A 13S Master & Slave BMS
- 【Brief】：
Model No: ZBH48V20ATCU-XDS.F (Slaves) / ZBH48V20ATCU-XDS.Z (Master)
Battery packed series: 13S
Battery type: Li-ion Battery Cell
Rating voltage: 48V
Max discharging current: 45A
Max charging current: 25A
Characters
1) Safety
This BMS is dual switch design. When one group of battery is loading, another group should be in shut down mode.
2) Emergency
Both battery packed have individaul switch. Once a group of battery break down another group should be replaced immdeiatey
3) Durable:
Two group of battery should be interchange automatically through the BMS controlled. Once the main unit is in low power status,
the successive power is provided by another unit
- 【Series】：Tailor Series
Introduction
This series concerned signal BMS system controlled dual battery packed. Due to the scooter adopted two battery packed, the running time should be longer than the normal one. Through the dedicated fast charger, it allow the charging time shortly. This BMS widely used in the far distance electric scooter
Application Scope
Electric Scooter/ Electric Tricycle
Features
1) The BMS designed based on 13 series which is the standard of electric scooter standard
2) UART interface can read the battery state and modified the BMS frameware
3) Two battery packed can be interchange the power automatically
4) Temperature sensor monitoring
5) Accurate SOC information
Coulomb electricity calculation, provide the accurate figure about the battery SOC
6) Support Mosfet failure detection function
7) Fully protection function
Once the main unit is in low power status, the successive power is provided by another unit
