<h2 class="section-title">Issue</h2>
<div class="section-description padding-bottom">Stopping and restarting a vehicle constitute mini-cycles of charging/discharging at very high currents. Although these mini-cycles allow a gain in range, they reduce battery life
significantly. This is especially true for vehicles that have to stop frequently in urban conditions, which are forced to replace their batteries frequently.<br><br>Battery life is a key economic and ecological factor for urban
mobility, which for now remains a sore point for the industry. <br><br></div>

<h2 class="section-title">Solution</h2>
<div class="section-description padding-bottom">Our solution integrates buffer supercapacitors between regenerative braking and the battery, to reduce or eliminate the number of mini-cycles of charging/discharging. The electronics provide
a gradual transition from load on the capacitors to load on the battery. <br><br>This enables: <br> - Efficiency gains, as the buffer returns 97% of stored energy as against 82% for a lithium
battery<br> - Durability gains, as a result of the protection provided by the buffer<br> - Reduced running costs (around 25 to 40 cents/km for an electric bus)<br> <br>In urban
conditions, battery life is doubled or even tripled for vehicles having to stop frequently. <br><br></div>

English French SYSTEM FOR DOUBLING THE LIFE OF ELECTRIC BATTERIES The solution incorporates a supercapacitor as a buffer between the regenerative braking and the battery. This prevents mini-cycles of high current battery charging/discharging. This doubles battery life in urban conditions, while increasing overall regeneration efficiency. ISSUE Stopping and restarting a vehicle constitute mini-cycles of charging/discharging at very high currents. Although these mini-cycles allow a gain in range, they reduce battery life significantly. This is especially true for vehicles that have to stop frequently in urban conditions, which are forced to replace their batteries frequently. Battery life is a key economic and ecological factor for urban mobility, which for now remains a sore point for the industry. YOUR ADVICE Do you agree with the observation that battery life limitation is a problem? Strongly disagree Disagree Agree Strongly agree Add a comment Is it critical? Not critical Somewhat critical Moderately critical Highly critical Add a comment What solutions do you know/use to address battery life issues? SOLUTION Our solution integrates buffer supercapacitors between regenerative braking and the battery, to reduce or eliminate the number of mini-cycles of charging/discharging. The electronics provide a gradual transition from load on the capacitors to load on the battery. This enables: - Efficiency gains, as the buffer returns 97% of stored energy as against 82% for a lithium battery - Durability gains, as a result of the protection provided by the buffer - Reduced running costs (around 25 to 40 cents/km for an electric bus) In urban conditions, battery life is doubled or even tripled for vehicles having to stop frequently. YOUR ADVICE Does this solution seem relevant to you to meet the challenges associated with urban mobility? Not relevant Somewhat relevant Moderately relevant Highly relevant Add a comment What are the strengths of this solution? 1Extended battery life before charging is needed 12345 2Extended battery life 12345 3Efficiency gains 12345 4Others (please specify in the comment section) 12345 Add a comment What are the weaknesses of this solution?
