Features

Power stage

• Dual-port architecture with separate control and current measurement for each port
• True short circuit breaking with ~ 1us reaction time and capacitive shortcut energy discharge circuitry
• Integrated triggerable fuse for maximizing safety in the case of transistor shoot-through
• High-precision bi-directional current measurement on both ports
• Triple battery voltage measurement (cells, pack, ports)
• Individually settable bi-directional short circuit protection for both ports (up to 850A)
• High continuous discharge current (+-250A), +-500A peak
• High continuous charge current (100A), 200A peak
• Capacitive, resistive and combined loads pre-charging with controllable current

Sleep management

• Low sleep current (<1mA)
• Ultra-low deep-sleep current (<50uA) (can be woken by charger)
• Ports can stay ON during sleep and be woken by load (~>20mA)
• Many wake sources (CAN, negative current draw, charger detected, button, KEY input, timer, etc)
• All protections stay active during sleep

Temperature management

• multiple integrated temperature sensors (balancer, switch)
• 2 temperature inputs (NTC or PTC sensors can be connected by selecting a parameter)

Cell management

• Individual undervoltage and overvoltage protection, cell health measurement
• Detection of correct connection of the cells
• Proportional control of balancing current with balancer temperature sensing
• Simultaneous balancing on all cells, balancing possible in all operational modes

Environment sensing

• Humidity and pressure measurement
• Measurement of the heatsink potential

Communication

• CAN - Galvanically separated communication
• UART - Galvanically separated communication
• USB-C - for debugging and tuning

Outputs

• Contactor drive output with PWM. The basic function is to switch off BATT + in the off state.

Inputs

• dedicated KEY input for a vehicle on/off control
• dedicated charge-detect input signal

Firmware highlights

• SOC and SOH estimation
• All kinds of overload, overvoltage, undervoltage, overtemperature, overtermperature protections
• Limiting values (Min, Max) can be set individually for all measurands; separately for derating requirement and for turning off the ports
• CAN streaming of immediate derating requirement for both current directions (for the motor controller)
• Periodic battery checks in sleep mode, automatic storage mode enter (discharge and deep sleep)
• Part of siliXcon platform, seamless cooperation with siliXcon controllers
• Self-diagnostics
• Detection of correct load and charger connection

Accessories for human interaction

• OLED display with button
• RGB LED bar
