Unitree H2 Charger

Key Features & Specifications

The H2 charger is built to handle the significant power requirements of a full-scale humanoid robot. Unlike smaller quadruped chargers, it features a higher voltage and wattage output to ensure the 75.6V battery system is replenished efficiently.

Technical Performance

• Voltage Support: Optimized for the H2’s 75.6V (maximum) lithium-ion battery system.

• Rapid Charging: Capable of recharging the robot’s 0.972 kWh (15Ah) battery in approximately 2.5 to 3 hours, significantly faster than standard consumer-grade chargers.

• Input Compatibility: Universal input range of 100V – 240V AC, allowing for seamless use in various international regions.

Intelligent Protection System

To protect the longevity of the high-value H2 battery, the charger includes an “Eight-Fold” safety protocol:

• Overcharge & Over-discharge Protection: Prevents cell degradation from voltage spikes or drops.

• Temperature Monitoring: Automatically adjusts or halts charging if internal temperatures exceed safe limits.

• Short-Circuit & Current Protection: Guards against electrical faults during high-power transmission.

• Balanced Charging: Ensures each cell within the 15Ah pack reaches equal capacity for stable robot operation.

Industrial Design

• Portability: Despite its high output, the charger maintains a compact form factor for easy transport between labs or work sites.

• LED Indicators: Simple visual cues provide real-time status updates on charging progress and battery health.

• Smart Connectivity: Built to interface with the H2’s onboard Battery Management System (BMS) for precise data logging and health checks.

Usage Scenarios

• Research & Education: Ideal for labs requiring quick turnaround times between trial runs.

• Industrial Maintenance: Ensures the H2 can remain operational for its ~3-hour runtime throughout multiple shifts.

• Field Deployment: The wide voltage input makes it a versatile tool for demoing the H2 in various global environments.

Note: For the best battery lifespan, it is recommended to use only the official Unitree H2 Charger, as the H2’s high-voltage power system is not compatible with chargers designed for the Unitree Go2 or H1 models.
