Six principles, make the market recognized multi-function car power

In fact, no one thought of emergency start-up power car market in the rise, it appears to have brought a lot of riders convenience, but the emergence of a product will always be accompanied by good and bad, and a formed multi-purpose car The emergence of emergency start-up power, all need to be designed to be fully demonstrated in front of consumers. So do you want to do the market recognized multi-purpose car start power, which principles to follow?mobile power plant

The following principles must be observed when designing a multi-purpose car emergency startup power architecture:

1, cooling.

Assuming that in hot (> 30 ° C), poor airflow, or even no airflow, we should design the thermal design based on the minimum efficiency of the DC-DC converter. And we also need to provide them with good air circulation conditions to dissipate heat, so as to achieve the best cooling conditions.

2, control costs.

In the design of automotive multifunction emergency power supplies, the cost is a factor that needs to be considered important in the design process. So we can easily design and trim a traditional, unoptimized power source at a given project budget, becoming a PCB type, with options for packaging and other design constraints.

3, layout and location.

The overall performance of multi-function car emergency start power will limit the layout of PCB components, power supply design, structural design constraints, high-chip integrated power supply design constraints. Therefore, in balancing the overall system performance, mechanical limitations and costs of automotive multifunction emergency power supplies, designers need to make realistic plans based on specific project needs.

4, electromagnetic radiation.

As things change, electromagnetic radiation will gradually produce with the electric field, the frequency of its electric field and the radiation determines its radiation intensity, a working circuit will be directly interfered with by other circuits. These negative effects are non-cancellable, so OEMs have set limits on the maximum electromagnetic radiation available to ECU units, minimizing these negative effects so they can be controlled.

5, voltage VIN range.

Everyone should know that the transient range of 12V supply voltage can determine the input voltage range of power conversion ICs. Among them, the most common automotive emergency power supply voltage range is 9V to 16V. However, due to environmental factors, conditions and other aspects of the use of automotive emergency power supply, the voltage may be ± 100V, so the industry standard ISO7637-1 defines the voltage range of automotive batteries.

6, Turn-off current (ISD) and quiescent operating current (IQ).

    If the number of automotive electronic control unit in the case of a sharp rise in the total consumption of the car battery will also be a sharp increase in consumption. Therefore, OEM manufacturers generally begin to limit the IQ of each ECU so as to ensure that the quiescent operating current IQ is within a controllable range. For example, the EU set the requirement is: 100μA / ECU, so the IQ of the ECU typically less than 100μA has become the standard for most EU vehicles.

So, want to be a qualified, standard car emergency start power, as long as the above six principles, can certainly be made to get any multi-functional market emergency power supply, we have always insisted Anga these principles to the user's vital interests To make products, we Anga car emergency start power supply in the market so popular. A good business is to be careful to make products, conscience products.
