Bardahl Coolant E-Tech -40°C (35625)

Bardahl Coolant E-Tech -40°C is a ready-to-use heat transfer fluid and coolant based on very high-quality ethylene glycol and the latest generation of non-ionic inhibitors. XCL E-TECH isto be used in fuel cellsystems and other electric vehicles subject to high temperatures. For EV, FCEV, FHEV, HE, MHEV, PHEV, RETROFIT, and "RANGE EXTENDER”. Bardahl Coolant E-Tech -40°C provides complete protection for all parts and compartments of the electric vehicle's thermal control system, from the battery to the engine. Its additive package protects the battery cooling plates, the power electronics heat sinks and the engine.
Thanks to its very low electrical conductivity and its ability to reduce heat, it provides the fuel cell system with long-lasting, stable electrical conductivity. Bardahl Coolant E-Tech -40°C is compatible with aluminum, stainless steel, copper, thermoplastics and elastomers commonly used in cooling systems.

• EV (Electric Vehicle)/BEV (Battery Electric Vehicle) : Electric vehicle whose electric engine(s) is (are) powered by a battery.
• FCEV (Fuel Cell Electric Vehicle)/Fuel Cell Electric Vehicle : An electric vehicle that generates its electricity from a hydrogen-powered fuel cell. The electricity produced is then used to power the electric engine(s) in the same way as in a battery-powered model. A battery is still present to recover energy from the electric engine(s) during braking and deceleration, and to act as a reserve of energy immediately available if sudden, strong acceleration is required. 
• FHEV (Full Hybrid Electric Vehicle)/non-rechargeable hybrid : A vehicle whose motive power is provided by a combustion engine and an electric engine, either in combination or in turn, depending on the situation. This type of vehicle cannot therefore be combined with a manual gearbox, and the range in 100% electric mode is around three to five kilometers.
• Hybridization : The combination of several types of engine to power a vehicle. An electric vehicle with a battery and an internal combustion engine that can be connected to the wheels as required is a hybrid. On the other hand, if the combustion engine is only used to recharge the battery, with no possible link between it and the wheels, then the vehicle is a 100% electric vehicle with a combustion generator. A hybrid car may or may not be rechargeable. However, the term 'mild' hybridization is used when a small electric engine (usually a starter-alternator) provides power to the combustion engine without being able to drive the wheels directly, which is more akin to an electric 'boost' than to hybridization.
• MHEV (Mild Hybrid Electric Vehicle)/micro-hybrid : A vehicle whose motive power is provided by an internal combustion engine, backed up by a small electric engine, usually in the form of a belt-driven starter-alternator to add power and supply on-board equipment in order to reduce fuel consumption. Micro-hybridization (also known as light hybridization) can, depending on the model, automatically shift the gearbox
  into neutral and cut the combustion engine, allowing the vehicle to coast along while providing on-board electrical power. However, a micro-hybrid vehicle cannot run in 100% electric mode.
• PHEV (Plug-in Hybrid Electric Vehicle)/rechargeable hybrid : A vehicle powered by an internal combustion engine and an electric engine, either in combination or in turn, depending on the situation. Thanks to the possibility of recharging from the grid, and with a larger-capacity battery than that found on a non-rechargeable hybrid vehicle (FHEV), the range in 100% electric mode reaches several tens of kilometers.
• Retrofit : The addition of a recent technology to an object that is older than that technology, and that was not originally designed to receive it. In the automotive industry, retrofitting mainly involves adapting an electric engine to replace an internal combustion engine.
• Electric vehicle with thermal generator/Range extender
• An electric vehicle whose electric engine(s) is (are) powered by a battery, which in turn is recharged from the mains by plugging into the electrical network or, when driving, by an internal combustion engine that is not connected to the wheels. This combustion engine therefore extends the range without stopping and acts as a generator or range extender.
