Toyota to Launch Solid-State Battery by 2027 – Here’s The Problem

Toyota has seemingly been lagging behind in the EV race but that might finally be about to change. With its in-house solid-state battery launch by 2027-28, Toyota has finally come around to mainstream electrification. Industry experts and customers were intrigued by Toyota’s decision to keep investing its time and resources in hydrogen and other alternative energy sources to power its future automobiles. While the entire industry is making a gradual shift towards EVs, Toyota was busy exploring all other possible avenues to arrive at eco-friendly mobility solutions. This doesn’t mean that it was averse to EVs. In fact, it had announced comprehensive plans to launch 30 BEVs (including Lexus cars) by the end of the decade. But in comparison to the legacy automakers and new startups, it was definitely sluggish. That is why this announcement of developing in-house next-gen batteries in association with Idemitsu was welcome news. However, there is a rather peculiar issue with that as well.

For these batteries, the EV owners will be able to charge from 10% to 80% in just 20 mins. After 2027-28, the Lithium-ion batteries will finally feature solid-state electrolytes. They will be able to offer a range of over 1,200 km with a 10-minute charging time for 10-80% SoC. Problem with Solid-State Battery from Toyota While all this sounds appropriate and promising, the Japanese automaker mentions that there will be enough solid-state batteries for a few thousand EVs even in 2027-28. As a matter of fact, by 2030 when the company plans to go into the “mass production” phase, there will only be around 10,000 batteries. Interestingly, Toyota wants to sell around 3.5 million BEVs by 2030, as per its plans. Surely, 10,000 doesn’t sound like much. Not to mention, even this will happen if the Japanese carmaker promises to keep its word. You might also like: Potential and Challenges of Electric Vehicle Battery Swapping Learn Electric Cars Says Toyota might well be late to the party, but that is not the only concerning thing. Its plans are still not convincing enough to make it one of the top players in the world in the electrification age. Our readers might already know that Toyota has held the position of the largest carmaker in the world on multiple occasions. However, transitioning into the EV age might change that. Firstly, it had been reluctant to give up on hydrogen and alternate sources of fuel and technology. Now that it has finally announced huge plans for EVs in the coming decade, its technology and commitment toward EV batteries seems lacking in terms of the volume it aims to sell. It would be interesting to see if Toyota makes any changes to the timeline or the volume before its sold-state battery launch.

Types of EV Battery Cooling Systems Liquid or Air

Which is Better EV Battery Cooling System – Liquid or Air?

13 Comments / Battery / By LEC Team

For achieving high thermal efficiency, EV batteries are needed to be kept within the optimal operating temperatures which is why the cooling systems for electric car batteries are critical. Liquid or air cooling system is the most widely used technique to keep an EV battery within the optimal thermal range. Lithium-ion batteries are influenced by temperatures a lot. In fact, that is a major drawback of these types of batteries. But these are energy dense, lightweight, relatively affordable and capable of fast charging, which is why these are mostly used in EVs today. However, an efficient thermal management system needs to be in place to keep the cells from getting too hot or cold to ensure a stable and maximum range and performance. You might also like: Top 5 Tips To Save / Earn Money From EV Charging You might also like: Mercedes Electric G-Wagon (EQG) to Get Silicon Battery Material Liquid vs Air EV Battery Cooling System Liquid EV Battery Cooling System There are two types of liquid battery cooling methods – Direct and Indirect. In a direct liquid cooling mechanism, the battery cells are in direct contact with the coolant. For this to work, the coolant needs to have low to no conductivity. However, there is still intensive R&D going on about this which is why we don’t see it in EVs at the moment. Indirect cooling is something that we have got accustomed to even in traditional internal combustion engines. It consists of thin metal pipes that are placed right next to the battery surface. The heat generated during discharging (when the car in is motion) is absorbed by the coolant (generally glycol or polyglycol) running in these metal pipes via conduction. As a result, the excess heat is taken away by the coolant and it recirculates over and over again. This is the most common method used to control the temperatures of EV batteries today. You might also like: 5 New EV Battery Technologies – Aluminium-ion to Niobium Air EV Battery Cooling System As the name suggests, air cooling systems use the principle of convection instead of conduction for heat transfer. The air circulates around the hot battery and absorbs the heat emitted by it. Needless to mention, this is quite an inefficient way to manage thermal balance. There were some earlier budget EVs that used to have this mechanism, but eventually, carmakers moved to liquid cooling systems. Other Types of Battery Cooling Systems There is also the fin cooling system that is used in many electrical appliances. You must’ve seen fans and cooling setups with thin fins. The principle used in this setup is also convection. These fins have high thermal conductivity which ensures that they absorb the heat. But installing fins inside the vehicles requires additional space and weight. Those are undesirable aspects in modern cars where packing efficiency is critical to liberating the maximum space for the passengers. Finally, there are also Phase Change Materials (PCM) which absorb heat and change from solid to liquid. As one would imagine, the reason why they are not used in vehicles is because of the change in volume. When matter changes forms, there is a change in volume as well. For instance, ice melts to form water. Ice needs compact space while the same amount of water needs more space in liquid form. This property of PCMs renders them useless for automobile applications. You might also like: Top Solid-State Battery Companies For EVs Learn Electric Cars Says In inference, due to the heat transfer capabilities of liquid cooling systems, these are much better than air cooling systems for EV battery cooling. Sure, there can be issues with the liquid cooling systems like leakage. But this system is designed in such a way that it doesn’t happen. In case it still transpires, it is ensured that the passengers remain safe. As far as corrosion is concerned, additives are added to the coolant to ensure great protection against any such issues.

They offer 2 years and 3 years of complimentary DC charging (certain kWh per month) respectively. Charging During Off-Peak Hours Yet another common way to save a lot of money while charging your electric car is the time when you charge it. You must know that charging at home using an AC charger is anyway cheaper than charging at a DC power station. However, if you charge at home during non-peak hours, generally from 8 PM to 6 AM, you might be able to charge at an even lower price. So, plan your charging cycles accordingly. You might also like: Top Solid-State Battery Companies For EVs Solar Energy to Power Your Home / EV There are many parts of the world, where solar is gaining momentum. People are installing solar panels in their homes to power their entire household. Needless to mention, this is particularly beneficial in those parts that are mostly sunny. Hence, if you install solar panels at your home and charge the EV using that source, the charging costs are bound to be extremely low. Selling Power to the Grid Another increasing trend around which startups are evolving is selling the surplus power back to the grid. We have already discussed how you should ideally charge your EVs during off-peak hours. During these times, you are paying the least amount of money to buy power. However, when you are not using your EV, you could sell it back to the grid at a time when the electricity rates are much higher, i.e., during peak hours. In this way, a symbiotic association could take place where you are using the grid to get power and also selling power to the grid to generate some profit. EV Charger Tax Credit & EV-Specific Electricity Rates Now, these are slightly nuanced measures that might be limited to only a couple of countries at the moment. But we are sure that more governments around the world could adopt it. The US government offers up to $1,000 in tax credit if you wish to install a charging station at your home. That is a necessity for EV owners and you could save some bucks in the form of tax credit. Similarly, the UK-based OVO Energy is a company that gives specific discounts for users to charge their EVs. The prices are exclusively designed for electric car charging allowing you to save some money. You might also like: How to Maximize EV Driving Range – Tips & Strategies Learn Electric Cars Says Despite the exponential growth of the EV industry in the last couple of years, we are still at a nascent stage of this promising EV revolution.

We are certain that such measures will become more common in more nations as we go forward. This is a great window to switch from traditional ICE-powered cars to EVs. Also, we understand that these practices might not work in every country at the moment. But the aim of this blog post is to make you aware of the kinds of possibilities that exist. This would also prompt you to keep an eye out for any such new method you might come across that will help you save or earn money using your electric car.

How to Maximize EV Driving Range – Tips & Strategies

10 Comments / Featured / By LEC Team

Electric cars look to be the norm going forward which is why it makes sense to acquaint ourselves with their behaviours and idiosyncrasies. Arguably the most common question among future EV owners is how to maximize EV driving range. As more vehicles get electrified, this is a valid question. Extending the distance an EV can travel on a single charge is critical for mass adoption and to appease range anxiety. In this blog, we shall explore several tips and strategies to improve electric driving range. This would range from optimizing driving habits and maximizing battery efficiency to utilizing charging infrastructure effectively. You might also like: Wireless Charging For EVs Could Be Revolutionary Technology How to Maximize EV Range? Regenerative Braking Firstly, let us commence by discussing a built-in feature that most EVs inherently possess – Regenerative Braking. During acceleration, the electric motor takes power from the battery to power the wheels. However, during braking, the kinetic and heat energy can be used in the reverse direction to get stored back into the battery. When the driver lifts his/her foot off the gas pedal, this reverse circulation of energy can bring the car to a complete stop. This is called energy recuperation or regenerative braking. This is a great feature that could be used on downhill slopes to get some juice back into the battery. Reducing Energy Consumption in the Cabin You might know that it is nigh impossible to get the exact driving range that is claimed by the company as per the WLTP or any other standardized test cycle. This is because the range depends on various factors including driving mannerisms and the use of energy-sucking components like HVAC, heated and ventilated seats, auxiliary audio systems, etc. Now we understand that you can’t switch off the AC when it’s scorching hot, but in the case of an emergency, you must know that turning all these functions off can help maximize the range. You might also like: Are Stricter Emission Norms Right to Push Mass EV Adoption? Battery Management and Maintenance An eminent aspect of electric cars is their battery management system. In fact, carmakers are burning a lot of cash in the development of the BMS for EVs. This takes into account how well the cooling system is, how will the battery perform outside the ideal temperature range, how often does a battery need maintenance, etc. Regularly monitoring the battery’s state of charge (SoC) and avoiding extremely high or low levels can help prolong battery life. Sticking to manufacturer-recommended maintenance schedules, including software updates and battery health checks, helps maintain optimal performance. Using Charging Infrastructure Prudently You would think what role can the charging infrastructure play in maximizing range, right? Well, it is well-known that prolonged fast charging of any Li-ion battery can reduce its life. Sure, it doesn’t degrade the battery too much too rapidly. But if you are planning to own an EV for 8-10 years or even beyond that, making a conscious decision of using DC rapid charging minimally can make a lot of difference. For this, proper planning is needed. You must develop the habit of charging your EV at your home or work using an AC charger. Restrict the usage of DC rapid charging for long journeys on highways. Driving Mannerisms Finally, the most effective way to maximize the driving range of an EV depends on the way you drive it. Now, this is true even to sequester the maximum fuel economy from your ICE-powered vehicle and this law holds true even in the EV world. As opposed to ICE cars, EVs are more suited for city driving and not high-speed scenarios on highways. Higher energy gets consumed in the latter case. Traditional cars are more efficient on the highways but consume a lot of fuel in bumper-to-bumper traffic. To squeeze the maximum range though, simple habits like using the throttle and brake pedal gently and not flooring it is the way to go.

As the name reflects, the electrolyte solution that is found between the cathode and anode of an electric car battery (or any other Li-ion battery used in other electronic gadgets) is in solid/gel form. In Li-ion batteries, this is in a liquid state which is what causes fire. But with solid-state technology, this electrolyte is in solid or gel form. Hence, the size and weight of the battery are reduced leading to increased range and faster charging times. However, more research is needed to produce these on a large scale. Lithium Sulfur Batteries Lithium Sulfur (Li-S) batteries use sulfur instead of complex, toxic, fast-diminishing and difficult-to-source elements like Cobalt or Nickel in their construction. This makes the batteries slightly lighter increasing their energy density which could be as high as around 500 Wh/kg compared to around 300 Wh/kg for regular Li-ion batteries. These can have around 1,500 charging cycles. However, the issues with these include polysulfide “shuttle” resulting in leakage of cathode material.

In this construction, Aluminium ions are used as charge carriers between the cathode and anode. Aluminium can exchange 3 electrons per ion which makes its energy density around 50 times higher than Li. Having 3 electrons has its advantages and disadvantages. The latter include relatively short shelf life and issues with heat, rate of charge, overall electrical behaviour and energy capacity. Niobium Batteries Finally, there are the exciting Niobium batteries that take 1 minute to recharge due to their layered molecular structure. Cambridge-based Nyobolt is working on this unique technology that uses Niobium anode reducing the charging time drastically. Even under severe temperatures, these batteries are less prone to catching fire. Their temperature gradient is just 8 degrees Celsius compared to around 27 degrees Celsius for regular batteries. While there has been significant development in the first two technologies with BYD and CATL having commenced the production of Sodium-ion batteries in mass-market EVs, the others still are in various stages of development and testing. It would be interesting to see which out of these (if any) dominates the space by the end of this decade. Also, chances are that these might co-exist or new technologies might also crop up.
