Energy harvesting compatible evaluation module kit
Maxell has collaborated on the development of a low current consumption∗1 evaluation module kit compatible with energy harvesting techniques such as solar electric generation, using a voltage-boosting DC-DC converter IC equipped with a ceramic packaged all-solid-state battery, LAPIS Technology Co., Ltd.'s (hereafter described as LAPIS Technology) charge control IC for energy harvesting, and ROHM Co., Ltd.'s (hereafter described as ROHM) Nano Energy™ ultra-low current consumption technology.
With this, the charging solution of the all-solid-state battery, which is compatible with power generation from sunlight and indoor lighting, can be easily examined. As it does not require a power supply, it is expected to be applicable in a wide range of fields from industrial applications to consumer products, such as monitoring devices for equipment and infrastructure, display devices, and wearable devices.
The low current consumption energy harvesting-compatible evaluation module kit combines LAPIS Technology's ML9077 charge control IC for energy harvesting, the BD8B133NVX voltage-boosting DC-DC converter IC equipped with, ROHM's Nano Energy™ ultra-low current consumption technology, and Maxell's PSB401010H and PSB401515H (currently under development)∗2 ceramic packaged all-solid-state batteries.

Maxell's all-solid-state battery, which features wide operating temperature range∗3, and has a long lifetime∗4 and a high safety level∗5, is attracting attention as a next-generation rechargeable battery. By facilitating evaluation at companies that examine adoption of all-solid-state batteries and energy harvesting-compatible power supplies, Maxell hopes they will be rapidly introduced in a wide variety of applications, helping to solve social issues.
- Low current consumption: The quiescent current (at non-switching) of the voltage boosting DC-DC converter IC (BD8B133NVX) is 180nA (Typ.). For details, please refer to the Nano Energy™ ultra-low current consumption technology product page.
- Nominal capacities of PSB401010H and PSB401515H (currently under development) are 8mAh and 16mAh respectively.
- Wide operating temperature range: Can be discharged at an environment temperature range from -50 to +125 deg. C under Maxell's test conditions.
- Long lifetime: Maxell's lifetime prediction result depending on various evaluations and analysis.
- High safety level: No firing or smoking in various safety tests conducted by Maxell, such as +200 deg. C heating, nail penetration, and external short circuiting.
