High and low voltage household energy storage lithium battery-Fully automatic thermal management series

2024-11-27

The ETBTMS series of household lithium batteries adopts a fully automatic thermal management system, CTP module-free technology, high-efficiency heat pump heating technology, and an aluminum alloy body design to expand the operating temperature range of the battery, increase the consistency between battery cells, and provide a more flexible appearance design, thereby achieving a new generation of household energy storage lithium batteries that are safer, more exquisite, and have an ultra-long service life.

Fully automatic thermal management system

EITAI independently developed lithium battery thermal management system (BTMS) is a lithium battery temperature control technology system that mainly uses circulating liquid as a medium for heat exchange.

1. ETBTMS has dual functions of heating at low temperature and cooling at high temperature. The working environment of the battery can be -20~55℃ .Accurate automatic control of the lithium battery inside the best working temperature of 10~35℃ .

2. The temperature difference between the cells is accurately controlled within 2℃.

3. Advanced heat pump technology, heating efficiency is 3 times that of traditional PTC electric heating film.

4. Independent research and development of silicone foam insulation technology, reduce the internal empty space, high temperature control efficiency, good effect, reduce loss, safe and efficient.

CTP Technology

The CTP technology (Cell To Pack) of EITAI household energy storage lithium battery directly integrates the cells into the battery pack, minus the module link, forming a module-free form to improve the overall energy density, and the battery thickness is only 18CM, compared with the home storage high-voltage stacked lithium battery products on the market, the volume and failure rate are significantly reduced, and the safety is greatly improved. There are no wiring harnesses and connector connections between modules, the structure is simpler, the installation is extremely convenient, and it also reduces the cost. Battery pack weight.

New Product Show

EITAI liquid-cooled batteries are available in high and low voltage options, and can be matched with mainstream brand inverters, and can operate normally in cold snowy days and high temperatures.
