Batteries

 

In August 2023 the Velite 6 lost its Plus tag and saw its drive range reduced from 518 to 430 km, and its entry price from 177,900 to 112,800 yuan, to face competition.  The ternary lithium (NCM) battery was replaced by a lithium iron phosphate (LFP) battery and the capacity dropped to 50.3 kWh.

The production of the Velite 7, based on the North American Chevrolet Bolt EUV, ended late 2022, and that of the Chevrolet Bolt EUV late 2023.  An updated model will be developed in America that will be equipped with durable and relatively cheap lithium iron phosphate battery cells.  The current Bolt uses an older battery cell structure made by GM partner LG Energy Solution.  The new Bolt will use the newer Ultium architecture, as in GM's BEV3 and BT1 platforms.

 

Electric motors

 

The 85 and 110 kW motors were built by Huayu, a subsidiary of SAIC Motor, and the 85 kW variant is the same as in the Roewe Ei5 (March 2018), which model has a drive range of 420 km, as its battery capacity of 52.5 kWh is similar to that in the Velite 6 Plus (vs 35 kWh for the regular Velite 6).

A note on drive range

 

In North America, EPA (Environmental Protection Agency) test procedures are used.

In Europe, the WLTC (Worldwide Harmonized Light Vehicles Test Cycle) replaced the NEDC (New European Driving Cycle) from 1 September 2019 (and in Japan from 1 October 2018).

In China, the CLTC (China Light-duty Vehicle Test Cycle) replaced the NEDC from 1 October 2021.

In terms of the severity of test conditions, EPA ranks first, WLTC ranks second, NEDC ranks third, and CLTC ranks fourth.
