ABLIC Develops Battery Protection ICs for Multi-cell Packs

Written by Stephen Vicinanza

ABLIC develops battery protection ICs for multi-cell packs. ABLICS battery protection ICs are a way to protect batteries from harm, such as overcurrent, over-discharging, and overcharging. ABLIC has been developing this technology for 30 years, since 1993.

The ABLIC battery protection ICs are focused squarely on automotive applications. The company is deeply involved in creating products that can help protect electric vehicles (EVs) as autonomous driving becomes more and more of a mainstream mode of transport. The demand for batteries as the power source for these autonomous and in-vehicle systems is growing.

The ABLIC automotive protective ICs are focused on protection within the battery management systems (BMSs) of automobiles. There are many uses for ABLICs battery protection ICs, for a major portion of the battery industry. There are applications that the company has said could be used for their ICs, such as cordless power tools, laptops, e-bikes, e-scooters, UPS as well as the automotive BMS.

In these use cases, the company sees the IC functionality to cover several functional areas.

  • Cascade function
  • Cell balancing
  • Wake-up
  • Temperature protection
  • Power saving
  • Output voltage limit

In specific areas of application, the IC types can be utilized effectively for different development types and product types.
