  • Patent number: 10236134
    Abstract: A battery thermal shield is used with a battery to reduce peak temperature exposure caused by a short of a battery from physical damage to the battery (e.g., the battery being pierced by a metal object). The thermal shield may be a highly thermal-conductive substance, such as a film, adhesive, gel, and/or other substance, that acts as an efficient heat spreader. Unlike a typical heat sink or heat fins, the thermal shield may have a low profile and be configured to spread a rapid onset of heat at a localized point or area (e.g., a location of an internal short) to a wider area to reduce a peak (maximum) temperature caused by a short of a battery. The thermal shield may be at least partially formed of graphite which may be adhered to the battery.

  • Patent number: 10205166
    Abstract: A novel hybrid lithium-ion anode material based on coaxially coated Si shells on carbon nanofibers (CNF). The unique cup-stacking graphitic microstructure makes the CNFs an effective Li+ intercalation medium. Highly reversible Li+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.

  • Patent number: 10199669
    Abstract: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.
