Problems solved by technology
[0003] 1. Due to the large starting current of the engine, when the battery provides a large current output in an instant, the output voltage is pulled down and is lower than the minimum input voltage allowed by the power conversion module in the computer equipment, and the output voltage of the battery returns to normal after the engine starts , this situation will cause the computer equipment to be powered off and restarted, which may easily lead to loss of unsaved data, damage to electronic devices or precision devices due to voltage shocks, etc.
[0004] 2. In the working mode of using the charger in the engine to charge the battery, during the driving process of the car, acceleration, deceleration, braking and other conditions caused by changes in road conditions may easily cause peaks, surges, fluctuations, etc. in the output voltage of the charger. If the situation is serious, it will cause a great impact on the computer equipment that needs to be powered on while the car is running, and in severe cases, it will damage the computer equipment and affect the normal use of the computer equipment during the driving process.
