When purchasing our company's onboard vehicle jammer device, we often ask the following question when confirming the technical specifications of the onboard vehicle jammer: by modifying the vehicle and installing the vehicle jammer in the rear trunk area of the vehicle, but without installing a generator, we use a large capacity battery installed in the vehicle to power the vehicle jammer, Would you like us to confirm if this power supply method is feasible.

When developing a vehicle modification plan, the onboard vehicle jammer  needs to consider the power supply method. As a recommended solution for interference equipment manufacturers, it is recommended to choose an onboard generator that matches the power consumption of the vehicle jammer. The single method of relying solely on batteries to power the vehicle jammer is not recommended if there are no special factors involved.

The commonly used high-power car mounted digital frequency interference devices nowadays, if they are in the full frequency range, are usually equipped with 18-24 interference modules. The power consumption of the entire equipment will reach 4KW to 6KW. The value of this power consumption is quite high, which is equivalent to providing 4-6 kWh of electricity per hour. If this type of power consumption is completely powered by batteries, considering the continuous power supply time of the battery to the digital frequency interference instrument, it should meet the requirement of stable operation for more than 2-3 hours. Even if a 48V battery pack is used, the total capacity still needs to be around 300Ah. For battery professionals, stacking such battery packs together can be quite frightening in terms of volume and weight.

If the battery pack calculated based on the above data is installed inside the vehicle, even if the volume factor is not considered, the weight inside the vehicle is a significant issue. Moreover, such a large capacity battery pack also poses certain safety risks.

The battery supplies power to the digital frequency interference instrument, and a DC to AC inverter needs to be added in the middle, which is not a good choice for inverters that can meet this ultra-high power.
