Our Remsa technical engineers tell you all about it<\/strong>.<\/p>\nAt first glance you might think it has no effect, but the impact of the way these vehicles operate on our braking system is considerable. Let\u2019s see why.<\/p>\n
REGENERATIVE BRAKING<\/h2>\n
Electric or hybrid cars have a regenerative braking system, a technology that optimises the energy efficiency of vehicles by converting some of the kinetic energy into electrical energy during braking.<\/p>\n
While traditional mechanical brakes dissipate this kinetic energy in the form of heat, it is possible to try to recover this heat to warm the interior of the vehicle, but this is not very common.<\/p>\n
In this way, vehicles with regenerative braking are more efficient by optimising energy consumption: up to 30% of the energy required by the vehicle can be supplied thanks to regeneration, making electric and hybrid vehicles a possible solution to the stricter environmental measures being adopted by regions such as North America, Europe and Japan with regard to combustion emissions into the atmosphere.<\/p>\n
THE PROBLEMS WITH REGENERATIVE BRAKING<\/h2>\n
So far it seems that regenerative braking seems to be all about the benefits, but is it?<\/p>\n
Well, no, regenerative braking is not all benefits, energy recovery has its limits, which are reached either when the batteries have no more electrical energy storage capacity (they are fully charged) or when the required braking power is too high for regenerative braking. In addition, the braking capacity of mechanical braking is greater than that of regenerative braking.<\/p>\n
Therefore, regenerative and mechanical braking are used in tandem. Although electric and hybrid vehicles generally use regenerative braking, which requires less use of the mechanical brake, its presence is necessary for safety reasons, including emergency braking, which requires high power and speed.<\/p>\n
In addition, at very low speeds the regenerative brake cannot generate sufficient resistance and is unable to bring the vehicle to a complete stop and the mechanical brake kicks in.<\/p>\n
The transition from regenerative to mechanical braking is key to the design of these vehicles as it must be imperceptible to the driver, who should at no point intervene in which of the two braking systems is being used. The braking of these systems is different and a poor design could result in a stumble at the transition point.<\/p>\n
EFFECTS ON THE MECHANICAL BRAKING SYSTEM<\/h2>\n
In principle, we could think that since the mechanical braking system is generally not used in normal city driving, the wear on the brake pads and discs is less and they are therefore more durable, which is \u201ctrue\u201d in that it implies that the mechanical braking system spends long periods of time without being used, causing the system formed by the brake discs and pads to rust or corrode due to exposure to environmental conditions.<\/p>\n
The following picture shows the effect of a corrosion test on the brake disc:<\/p>\n
This oxidation drastically reduces braking performance, which is a critical problem. If a vehicle affected by this phenomenon has to perform an emergency braking manoeuvre, the braking system may fail and cause an accident.<\/p>\n
CONTINGENCY MEASURES<\/h3>\n
To prevent this from happening, it is essential that electric vehicles undergo regular inspections to check the mechanical braking system. Electric vehicles require less maintenance, which means fewer trips to the workshop and much more time before someone with sufficient knowledge of the subject checks our brakes to see if they are in good condition.<\/p>\n
The reason why hybrid and electric vehicles require less and easier maintenance is because they have fewer elements subject to wear and tear, and the absence of most mechanical components means that they do not require maintenance of fluids, filters etc. On the other hand, electric motors have far fewer parts, which also means less maintenance.<\/p>\n
This measure seems to some brake pad and disc manufacturers to be insufficient, and in order to avoid the aforementioned oxidation phenomenon, the possibility of introducing an expiry date on brake pads is being studied, with the aim of preventing oxidation of these components and ensuring that they are serviced more frequently. We also recommend checking the brake fluid in the same way as for combustion vehicles.<\/p>\n
In addition, the trend towards longer vehicle life has stabilised in recent years.<\/p>\n

Hoch<\/em><\/p>\nThis implies higher requirements for corrosion protection and increased wear resistance of components, while increasing the need for ZnNi sealants and duplex coatings (electrolytic coatings with topcoat) on brake pads.<\/p>\n
BRAKE PADS FOR ELECTRIC AND HYBRID VEHICLES<\/h3>\n
The friction material used for these vehicles has been specifically tested on hybrid and electric vehicles to ensure the best performance also in this case.<\/p>\n
Both research centres and leading friction companies are currently working to define specific test protocols that best simulate these specific operating conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
