Features
- The app supports 14 languages and displays detailed battery voltage, temperature, current, and capacity data, along with configuration settings.
- Protection against overcharge, overdischarge, high and low temperatures, overcurrent, and short circuits.
- Protection activates when a configured threshold is exceeded. Voltage, current, and temperature each support two levels of protection settings.
- Manual and automatic sleep modes.
- Activates on first power-up. After entering sleep mode, it can be activated by charging or connecting a load.
- Supports use with an inverter, without communication between the devices.
Applications
- Electric two-wheelers, three-wheelers, and scooters.
- Small electric tools, including garden tools.
- Light-duty energy storage, including portable outdoor power systems.
Core Technology
- Master-Slave Cascaded Architecture
A master controller with multiple slave modules provides segmented management and scalable expansion for large high-voltage battery systems.
- High-Voltage Platform up to 1000V
Designed to meet the requirements of large-scale energy storage and high-voltage power battery systems.
- Modular Distributed Management
Each slave module independently manages its battery section for easier system expansion and fault localization.
- Independent Pre-Charge Control
A dedicated pre-charge relay and resistor reduce inrush current during high-voltage system startup.
- Real-Time Pre-Charge Detection
Pre-charge status is determined by load-side voltage changes rather than relying only on a fixed time delay.
- Dual-Side Voltage Detection
Battery total voltage and load-side voltage are monitored simultaneously for improved system status detection.
- Centralized High-Voltage Circuit Control
The master controller centrally manages pre-charge, charge and discharge relays together with overall system operating logic.
- Time-Division Balancing and Sampling
Balancing and voltage sampling operate separately to reduce measurement interference caused by balancing current.
- Hardware-Software Coordinated Protection
Software protection logic works together with high-voltage relay control to enhance system-level protection.
- Highly Configurable High-Voltage System
Series count, voltage, current, relays, shunts and pre-charge configurations can be tailored to specific project requirements.
