FLEXPOINT BATTERY SAFETY FAILURE INDICATOR DESIGN
One indicator of a failing battery is a buildup of pressure due to the breakdown of organic solvents. By monitoring this expansion with Flexpoint’s Battery Expansion Sensor (BXS), the battery will shut down before costly damage to equipment occurs or lives are endangered.
Integrating BXS by Flexpoint will give you and your customers an added layer of protection and peace of mind. Be safe. BXS.
Flexpoint’s patent pending BATTERY EXPANSION SENSOR or BXS, is designed to detect and stop a Lithium ion or Lithium Polymer battery from charging or discharging, preventing a thermal runway; one of the major way’s battery fires occur. Li-ion and Li-polymer batteries are used today in everything from phones to electric cars.
Li-ion and Li-polymer batteries are used today in everything from phones to electric cars. Flexpoint’s patent pending technology protects these batteries, their products and those who use them every day, measuring the expansion or swelling of the battery effectively stopping a potentially dangerous state.
Batteries become over heated, over charged, or simply fail due to old age. When this occurs, it is possible for the inner cells of the battery to outgas a flammable electrolyte mixture, causing the battery to swell. The Flexpoint Sensor addresses the swollen battery effect, as batteries are designed to contain as a failsafe the measure of out gassing. The Flexpoint Swell Sensor detects the condition, effectively shutting down the short circuit. Without this type of detection, some batteries can eventually reach temperatures over 1000º F.
Flexpoint believes this low-cost reliable solution that can handle even the harshest environments, will save lives, and prevent injury.
General Description
The Flexpoint Battery Expansion Sensor (BXS) is a carbon-based resistive sensor that can measure the expansion of Lithium Ion, Lithium Polymer, and other batteries due to accumulating gasses. Batteries tend to expand due to age, overtemperature and overcurrent. The BXS is an analog sensor but with a tiny IC can connect to the system using an I2C interface.
