Applications
When the vehicle stops briefly (such as waiting at a red light or stuck in traffic), the engine shuts off automatically. When the driver releases the brake or steps on the accelerator, the engine restarts instantly. It can reduce fuel consumption and exhaust emissions at idle speed.
· Fuel vehicle start-stop system: Replace lead-acid batteries, extend lifespan, and enhance reliability.
· Hybrid electric vehicle (HEV): In combination with an energy recovery system, it can cope with frequent charging and discharging.
· Special vehicles: such as forklifts, construction machinery, and other equipment that require instantaneous large currents.
