Customer and vehicle background

A modified car that requires long-term stable power supply

This vehicle is mainly used for[Rescue operations/outdoor construction/communication support/mobile services/long-distance travel]The car is equipped with:

• [Device 1, such as lighting system]
• [Device 2, such as communication equipment]
• [Device 3, such as car refrigerator or tool equipment]
• [Device 4, such as inverters and AC loads]

These devices are mainly powered by household batteries. The vehicle is at[Specific operating conditions]Possible continuous workdurationIt is necessary to obtain stable energy replenishment during driving and parking phases.

The problems faced by customers

The original power supply method is unable to meet the demand for new equipment

Before the modification, the customer mainly encountered the following problems:

1. Insufficient speed of recharging daily batteries
   [Explain the original power supply method and its impact]

2. Lack of proper management of start-up batteries and household batteries
   [Explain whether there are issues such as over discharge, unstable current, or inability to reverse power supply]

3. Limited energy source during parking period
   [Explain whether solar energy or external batteries need to be connected]

4. Unable to visually view the running status
   [Explain what information the customer wishes to view through the screen, app, or upper computer]

5. Modification space and interfaces are limited
   [Specify requirements for installation dimensions, heat dissipation, wiring, interfaces, or protection]

It is recommended to provide a simplified problem diagram here, such as the relationship diagram of "starting battery - living battery - vehicle load".

ENERCHG Solution

Establish a dual battery energy system with EC-D122 as the core

After evaluating the vehicle voltage platform, battery type, load power, generator capacity, and installation space, the project adopts the following configuration:

The main functions implemented by the system

• **During driving: * * Use the vehicle's power generation system to replenish the battery for daily use.
• **During parking: * * Charge the living battery through solar MPPT according to the configuration.
• **When needed: * * Use household batteries to reverse charge the starting battery.
• **During operation: * * Through[APP/Screen/Host Computer]View voltage, current, temperature, and operating mode.
• **In abnormal situations: * * Help users check the system in a timely manner through device protection and status prompts.

Image suggestion: Place the system wiring diagram of the project and label it as "schematic diagram, actual wiring is subject to the corresponding model manual".

Installation and debugging process

From vehicle evaluation to system delivery

The project will be implemented according to the following steps:

1. Confirm requirements
   Collect vehicle models, battery parameters, generator capacity, load conditions, and usage scenarios.

2. Evaluation system
   Check the voltage range, charging current, cable specifications, insurance configuration, installation space, and heat dissipation conditions.

3. Complete installation
   Install EC-D122 on[Installation location]Complete the connection of the startup battery, life battery, IGN, and related circuits.

4. Parameter Settings
   according to[Battery Type/BMS Requirements]Set charging mode and related parameters.

5. Run verification
   Verify the functions of driving charging, reverse charging, solar energy input, status viewing, and protection separately.

project results

What improvements have customers achieved

After the system was put into use, the following effects were achieved:

• During the driving process, it can continuously recharge the daily battery;
• Can be used when parking[Solar Energy/External Battery]Supplementary energy;
• When assistance is needed to start the battery, reverse charging can be performed;
• Users can access it through[APP/Screen/Host Computer]View device status;
• The charging path and control method of the electrical system are clearer;
• For future additions[Equipment or Function]Reserved expansion space.
