|   Customer Background & Demand

The world’s leading electric vehicle and energy company is accelerating the world’s transition to sustainable energy through electric vehicles, solar panels and comprehensive renewable energy solutions for homes and businesses. It is a benchmark for global electric vehicles and energy companies.

The company’s home energy storage products can storage solar energy or charge during low peak periods of grid electricity consumption; during power outages or peak electricity consumption periods, the stored electricity can be released to power homes and new energy vehicles.

While the equipment is charging and discharging, the battery pack and inverter will generate a lot of heat. This customer chose the most efficient liquid cooling method, an intelligent and low-temperature -40°C resistant electronic cooling pump is the core component of cooling system. However, water pump leakage and electronic failure are fatal risks of liquid cooling systems.

After the customer compared many water pump suppliers from South Korea, Japan, China, etc., TOPSFLO relied on professionalism in the micro pump industry and the pursuit of extreme quality, the customized water pump solution (TL-B10 Household energy storage cooling pump) was recognized by the customer.

1. Structural sealing design: Leakage is always a common technical problem in the pump industry. For better sealing, TOPSFLO designed a multi-chamfered water inlet and outlet connection method for customers. With the support of high-precision molds, the water inlet and outlet have a high surface finish and are more tightly sealed with the liquid cooling pipe;

2. Verification of low temperature resistance -40°C: Customer’s equipment is mainly exported to Europe and the United States, and is generally installed outdoors. There are many extremely cold weather, the water pump must meet the automotive grade low temperature resistance -40°C. TOPSFLO adopts internationally renowned brand raw material, and its temperature resistance and reliability have reached the industry’s cutting-edge level. Before mass production, water pumps undergo multiple verifications such as low-temperature operation at -40°C, storage at -40°C, low-temperature start at -40°C, high and low temperature shock at -40°C & 120°C, the water pumps still not leak even under extreme environments;

3. Intelligent design: according to the battery temperature requirements, real-time signal feedback and intelligent speed regulation can maintain the stable operation of the system, prolong the life and save energy.
