Rechargeable battery for IoT energy harvesting

The model RHB-1530 is an integrated pulse capacitor and rechargeable lithium battery that provides large pulse discharge capability under extreme temperature from -40°C to 85°C. With a low trickle charge current requirement and a high energy capacity, says the company, the RHB-1530 is ideal for use in energy harvesting devices for wireless IoT applications, where the unique power signatures of wireless sensors put a strain on regular batteries.

With the increase in intelligent sensing, sensors can capture and analyze machine signatures, monitor for alarms and environment, be network aware, and transmit to customers networks. This results in power requirements ranging from small current drains (<1 mA) when monitoring to large pulses (150 mA to 250 mA for Wi-Fi) when transmitting, dropping battery output voltages to unusable levels in undetermined times and considerably shortening standard battery life cycles.

“Technologies to extend the life of IoT devices without yearly battery replacements has been a focus of our R&D at Xidas over the last few years,” says Sourabh Dhillon Director of Business Development. “Working in partnership with the National Science Foundation (NSF), we are introducing our first four (4) products this month.”

“We were surprised with the amount of work engineers needed to do just in battery selection with regards to satisfying the unique behavior of wireless devices, particularly when it comes to integrating energy harvesting sources,” says Dhillon. “The RHB-1530 becomes the perfect energy storage companion for solar, vibration, thermal, RF or other energy harvesters used in IoT solutions.”

Measuring 30.0 (H) x 15.1 (D) mm and weighing 10.0 g, the RHB-1530 has a working voltage of 3.6 V to 4.0 V and a capacity of 240 mAh. The battery is designed for a 10 year life, says the company, and has enough capacity to run typical IoT devices for a week in case of harvested energy downtime, allowing enough time for customers to resolve i.e., malfunctioning machinery.

Pricing is $12 each (10-999 qty).
