Li-Ion Battery Monitoring and Control Module for Spacecraft

Description

The new Li-ion battery monitoring and control module is designed to neutralize the voltage unbalance of battery cells and to collect and compile telemetric data on key parameters of the battery.

Specifications

• Feed DC voltage range: 23 to 34 V.
• Voltage measurement and binary coding on 23 batteries.
• Range of voltage values: -1.5 to 4.5 V.
• Working voltage range: 2.7 to 4.2 V.
• Absolute error of working range measurement: ±10 mV.
• Input resistance of voltage measuring circuits: at least 100 kOhm across entire operating temperature range.
• Temperature measurement error: ±1̊C.
• Battery balancing current: 0.2—0.4 A.

Advantages

1. The module makes it possible to achieve the optimal operating properties and maximum life of the Li-ion battery.
2. High reliability due to implementation of the backup principle.
3. Can be used outside of a pressurized container.
4. Service life: 15 years.

Application

Li-ion and other types of batteries.
