It is definitely the right time to be deeply involved in battery technology, as it moves to the forefront of many industries including automobiles, stationary storage, aerospace, telecom, and consumer electronics. As battery technology advances, it is also causing an increase in the competition in the market and you’ll need a plan to set yourself apart. In this video, Akshay talks about how battery technology...Continue Reading
Decoupling capacitors are commonly found in circuits and can cause unintended issues if the design is not thought through fully. Let’s first understand what decoupling capacitors are. There are usually 0.1uF, and sometimes 2.2nF capacitors that are placed between the supply rails and ground to help prevent the transmission of noise through the power lines in...Continue Reading
I teach an online course on battery management and was looking for an inexpensive off-the-shelf product to see what could be learned from it. Here’s one that I found on Ebay that claims to be a BMS for up to four series cells. Why should you spend the next 5 minutes reading this article? You’ll takeaway two...Continue Reading
The concept of Kelvin sensing is explained below and why it is useful in battery voltage sensing. A current carrying conductor drops voltage across it, and in battery packs this current can be really high at times, which means that the voltage dropped will also be higher. The voltage sensing circuitry is usually far away...Continue Reading
In 1969, Nippon Calculating Machine Corporation approached Intel to design 12 custom chips for its new Busicom 141-PF printing calculator. Intel engineers suggested a family of just four chips, including one that could be programmed for use in a variety of products, setting in motion an engineering feat that dramatically altered the course of electronics....Continue Reading
Some ADCs in the market allow you to read differential voltage. How is this different from single ended voltage? Single ended voltage is the potential difference between a node and ground. Differential voltage is the potential difference between two nodes. A use case of measuring differential voltage is to measure the current flowing in a...Continue Reading
Dyson plans to enter electric cars business :Best known for slick-looking vacuum cleaners and hand dryers, James Dyson has already stated his intentions to tackle a completely different machine — the electric car. Dyson is planning a trio of new EVs for the next decade that will also adopt a solid-state battery pack, , embarking...Continue Reading
Low Speed two wheelers: Customers buying low speed Electric two wheelers (both with lead and Lithium batteries) are a happier lot as the initial price of these vehicles after subsidy become attractive (Rs.27000 to Rs.50000) and the running cost are also just 70 paise (incl battery replacement and charging cost) against Rs 1.30 /km of...Continue Reading
For the last 1.5 years, the customers in some of the EV segments like E- Scooters are being offered EVs at two price points corresponding to the level of technology, speed and power. However only 2% customer have really shifted to higher speed products. The major barrier being the prices and the diminishing TCO advantages...Continue Reading
