Revolutionary Device Cuts Charging Time, Extends EV Range
In independent testing, the Dectravalve demonstrated its ability to reduce the charging time from 30 minutes to approximately 10 minutes.
- A groundbreaking heat control system is set to significantly reduce charging durations, enhance driving range, and decrease battery wear in electric vehicles.
- It is known as the Dectravalve and can be installed on any battery, regardless of its chemical composition.
- The gadget can independently cool or warm up to four separate battery areas without any mixing and with a single entry point.
Maintaining the battery of an electric vehiclethe appropriate temperature range is crucial. This is why nearly all new electric vehicles come equipped with a heating and cooling system that allows the battery to be charged quickly and safely, while also maximizing its range regardless of the weather conditions.
Nevertheless, developing an effective thermal management system is neither simple nor inexpensive. Typically, an electric vehicle battery includes a cooling plate positioned above or beneath the battery modules. This approach works for most scenarios, but it can result in certain cells becoming excessively hot if they are located too far from the cooling source. Should one cell overheat, it can cause the entire battery pack to limit its power intake or output.
Currently, there is a company that claims it can address this issue for a fraction of the cost of creating an entirely new battery pack. It is known as the Dectravalve, developed by the United Kingdom-based company Hydrohertz.
The company states that the compact device's primary advantage is its capability to provide "exceptionally accurate" heating, cooling, or energy recovery for an electric vehicle battery. It features a single coolant inlet and can manage up to four zones separately without requiring multiple actuator valves or complicated piping. Hydroherz asserts that the Dectravalve can focus and separate heating or cooling to particular areas without any cross-flow, which can greatly enhance the efficiency of contemporary high-voltage batteries.
To back up their claims, the startup had their device tested independently by the Warwick Manufacturing Group (WMG). A 100-kilowatt-hour lithium iron phosphate (LFP) EV battery equipped with the Dectravalve underwent fast-charging, and the outcomes were remarkable. The hottest cell in the pack remained below 112.1 degrees Fahrenheit (44.5 degrees Celsius), with a temperature variation across the pack of only 4.68°F (2.6°C).
In contrast, standard electric vehicle batteries can reach temperatures up to 132.8°F (56°C) under extreme conditions, but this usually triggers power reduction to prevent cell damage. In practical situations, this leads to extended charging times.
Hydrohertz asserts that its device can address this issue without requiring a complete redesign of the pack. In tests, the Dectravalve demonstrated that charging times can be reduced by as much as 68%, meaning charging sessions could last around 10 minutes instead of 30.
Maintaining an electric vehicle battery at an optimal temperature, regardless of external weather conditions, can enhance driving range, according to a UK-based company that reports an increase of up to 10%. Additionally, this approach extends battery life by reducing stress on individual cells over time, leading to slower degradation than with traditional thermal management systems.
With Dectravalve, there is no 'shared circuit' that could lead to broader thermal contamination due to an overheated cell group," said Martyn Talbot, chief technical officer at Hydrohertz. "This prevents a thermal 'domino effect' where hotspots spread rapidly, and also guarantees that each part of the battery gets precisely the cooling it requires. The outcome is a clean, regulated thermal environment throughout the pack, with no trade-offs or cross-contamination.
Talbot, possessing almost two decades of practical industry experience as an electrical and mechanical engineer, collaborates with Paul Arkesden, who has recently been named chief executive officer. Arkesden previously served as Senior Vice President of Engineering at Singer Vehicle Design and Head of Engineering at McLaren Automotive, where he oversaw the development of the P1 hypercar's powertrain.
It all seems quite intriguing, but it depends on car manufacturers' readiness to implement such a device. It's not straightforward, but it is possible. Just consider Yasa–its axial flux motors were so impressive that Mercedes-Benzsnatched the startup and transformed it into a fully owned subsidiary.
