Propulsion By Batteries/Cells TRIZ Cases

Through holes in the insulating film relieve cell expansion at connecting-sheet protrusions, preventing tears and short-circuit risk.

Location-based charging guidance uses user travel patterns and battery usage to limit rapid charging, reduce battery wear, and ease EV range anxiety.

A laterally guided tracking device keeps the current collector aligned with overhead slotted conductors, extending EV range with safer contact.

Regenerative braking and vehicle-to-vehicle charging requests let an EV recharge while driving, reducing charging stops and arrival delays.

Integrated electrical tracks in a composite battery compartment cover replace separate cables, simplifying cell connection and insulation handling.

Vehicle pitch triggers an enhanced fuel cell purge routine on downhill grades to clear water, prevent freeze blockage, and limit hydrogen use.

An integrated label-handle lets the battery module be gripped for replacement while reducing case volume and eliminating separate handle fabrication.

Motor-generator dolly wheels recover braking energy and add torque assist, improving fuel economy and trailer maneuverability.

A heat-shrink elastic band seals the battery pack enclosure seam, accommodating tolerance stack-up while minimizing packaging space.

Using steel and aluminum frame units together cuts battery case weight and cost while preserving rigidity and impact protection.

Latch-on clamp elements replace screws to seal traction battery housing shells evenly, simplifying service and reducing leak and chip risks.

A linear-adjustable holder mount lets the battery sit close to the drive unit, fit different battery sizes, and avoid frame mounting interference.

Rotational coupling shifts terminal contact sideways, reducing insertion collisions and load damage while improving battery pack connection durability.

Predictive road-load and battery-capacity control sets a sustainable vehicle speed to avoid sudden power drops on climbs or in heat.

Charging during towing uses the motor as a generator and vehicle communication to raise battery charge without delaying travel.

A valve and winding mechanism stores fuel cell condensate, then releases it at a chosen location to avoid floor contamination and slip hazards.

Integrated plate cavities cool thermal-event gases and trap hot particles inside the battery housing, improving EV pack safety without extra weight.

Regenerative powered wheels turn a passive converter dolly into a steerable trailer shunter with remote or autonomous positioning.

Riveting the nut plate to the busbar tab resists assembly forces, preserves hole alignment, and avoids resistance, heat, and false torque readings.
