Tailored portable solar charging solution for European customer

The European customer has failed in turning their idea into feasibility for twice because of the previous suppliers being unable to translate the customer's ideas into feasible solutions.That resulted in the controller unable to make the system work.They not only required an advanced controller for the whole system,but also required a high-energy lithium ion battery pack.They had been in trouble for a while until they found Yilai Power team,which is experienced in tailoring solutions based on customers’ requirements.

1,Project Background & Challenges

Yilai Power team carefully evaluated the customer’s ideas firstly,and sorted out three main requirements:

1>The customer wanted to charged the system with two methods,either via the dedicated solar panel (MPPT integrated) or via mains power using an adapter.

2>They also want the system to be able to communicate with the lithium batteries’ BMS,reading status of the battery meaning,such as SoC,healthy status,cycle lifes...

3>The system can stably supply power to most of the consuming devices in the market,including laptops,tablets,phones,toys,drones,electric shavers,beauty devices,massagers ,portable ice maker,portable fan,neck fan etc..

2,Our solution & Implementation

1>Define the electrical parameters,including input power from solar panels and mains power,li ion battery 18650 configuration,output connector type,communication method,display and certification requirements.

2>Tailor the controller solution by designing MPPT schematic and layout,AC-DC charging circuit,DC-DC output,MCU controller.

3>Tailor The 24v lithium ion battery BMS which features with avoiding over-charging,over-discharging,over-current and short circuit,reading status of the deep cycle li ion battery and communicating with the main controller.

4>Build mock-up sample to verify the design and do compatibility test between controller and deep cycle lithium battery BMS.

5>Optimized the design and pilot run for the first batch.

3,Customer Satisfaction

The customer had wasted more than 6months with other suppliers and got failed experiences.Yilai Power team resolved the customer’s pain points and the final product successfully passed on-site verification test, with the BMS seamlessly connecting to the solar panel, li ion battery types and controller PCBA, which deliver outstanding performance.
