Abstract

Battery management systems (BMS) are crucial for satellites to maintain a reliable energy source. Today, lithium-ion batteries act as the solution to reduce the cost and weight of satellites, yet still come with safety concerns.

The combination of the high energy density of Li-ion and flammable material associated with batteries can be hazardous due to thermal runaway, overcharging, improper balancing, and the chance of experiencing a short. Currently, there are no radiation-hardened balancer/monitor ICs with the ability to sense battery state of health and state of charge.

This poster highlights a discrete, autonomous, and reliable BMS approach that provides high radiation performance, precise cell voltage monitoring, fast overcurrent protection, temperature sensing, and balancing capabilities
