IT Home (IT之家) June 24 news, according to foreign media Autocar reported today (24th), energy giant Shell announced the Triple10 Challenge concept for pure electric small cars, hoping to achieve generational improvements in charging speed, energy efficiency, and vehicle weight reduction.

According to IT Home (IT之家), "Triple10" represents three goals.

• Using common 175kW fast charging piles, complete rapid replenishment in 10 minutes;

• Drive 10 kilometers per kWh;

• Control the total life cycle carbon dioxide emissions of the vehicle to 10 tons.

Shell hopes to prove through the Triple10 Challenge that new technologies can make pure electric vehicles for the mass market more attractive. Shell also uses this to showcase special working fluids and lubrication products for pure electric vehicles., striving to increase procurement from major automakers.

Shell has jointly developed with Northamptonshire engineering company RML an immersion liquid-cooled battery. The battery contains two sets of cylindrical cells, all immersed in a non-conductive insulating fluid developed by Shell, which directly carries away heat. Traditional pure electric vehicle batteries usually have cooling pipes arranged above the battery module, and the coolant does not directly contact the cells.

Shell says immersion cooling can significantly improve thermal management efficiency, keeping the battery at its optimal operating temperature most of the time.

Toby Rockstroh, Shell's Energy Application Test Manager, pointed out that many electric vehicle models have peak charging power exceeding 300kW, but limited by cooling capacity, it can usually only be maintained briefly.."When the battery cell temperature approaches 60 degrees Celsius, the thermal management system will actively reduce the current, causing the charging power to drop. Overheating of the battery cells can also accelerate performance degradation. Our system does not have this problem because thermal limitations are eliminated."

In addition, stronger cooling capacity can improve kinetic energy recovery efficiency.

The battery of the Triple10 Challenge has a usable capacity of 32 kWh. Shell claims that the battery can continuously withstand 175 kW throughout the charging processand can charge from 10% to 80% in just 10 minutes.

Shell believes that immersed liquid cooling can create a virtuous cycle in vehicle design. With improved cooling efficiency, vehicle energy consumption decreases, thereby increasing actual range; shorter charging times also alleviate consumers' range anxiety. As a result, smaller-capacity batteries become more acceptable to the market, and vehicle weight and cost can be further reduced.

Due to the lower operating temperature of the battery,The three electric systems can also share the same set of radiators, eliminating the need for a separate cooling device for the battery, thereby reducing the number of components, weight, cost, and system complexity.

The Triple10 Challenge also extensively uses recycled and natural materials. The chassis is made of recycled aluminum, and the carbon dioxide emissions during production are reportedly only 10% of that of primary aluminum.The roof and wheels use recycled carbon fiber, while the interior fabric uses flax fiber.

Lars Nielsen, Global Business Development Manager of Shell Lubricants, believes that the technical route of the Triple10 Challenge is more suitable for urban pure electric small cars. Consumers who purchase long-range large SUVs usually live in residential areas with fixed charging conditions, and can recharge at night through wall-mounted charging piles, with low reliance on public fast charging.
