Hina Battery presents sodium-ion battery for commercial vehicles
At a dedicated event, Hina presented its ‘Hina Battery · Haixing’ solution, which will consist of four products at the start – two of which are aimed at local transport and two at the logistics sector, as reported by CN EV Post.
All products use battery cells with an energy density of over 165 Wh/kg and, according to the company, can be fully charged in 20 to 25 minutes. Hina states that even with constant fast charging, the battery life can be more than 8,000 cycles.
This is likely to be related to very little heating during fast charging. Hina Batteries claims that the temperature in the battery pack should rise by less than ten degrees Celsius during fast charging. That suggests that the cells have a low internal resistance. If the cells do not get too hot when the charging power is high, the stress on the cell chemistry is also reduced, which in turn leads to a longer service life. The battery is also said not to be very sensitive to temperatures when the vehicle is in operation: Hina says that it has a stable discharge performance in a window of -40 to +45 degrees Celsius.
Compared to existing conventional battery solutions for commercial vehicles – i.e. lithium-ion-based – Hina’s CEO Li Shujun said Hina’s sodium-ion battery solution can provide higher performance at significantly lower cost.
Hina Batteries was founded in 2017 and specialises in sodium-ion batteries. So far, the Na-ion cells are mainly used in electric two-wheelers and stationary energy storage, but they are also already being used in the first electric cars: in 2023, a test vehicle developed by Hina and Sehol (a JAC and Volkswagen brand) with a sodium-ion battery was presented. In January 2024, the first JAC production model Yiwei 3 with such a battery was delivered by Hina.
